Like the rest of us, he's on a tight budget.<br />
All the bargains were getting snapped up before he could get a look in.<br />
Then one day they re clearing out some storage that's been sitting a while and on a pallet sits a unimig 175 solid state mig/ stick welder.<br />
Wire feed no longer regulating. One fixed low speed all the time.<br />
Some sweet talking later and the mig is his.<br />

Initial hopes were that the pot for the wire feed is failed but it tested fine.<br />
The wire feed is regulated by this card.<br />

Priced a replacement at $220.<br />
<br />
Plan B.<br />
<br />
I got a PWM dc motor speed card for something a while back and decided to set up an alternative power supply and regulator for the wire feed. Bypassing the wire feed circuit while retaining the other functions of the card.<br />
A 4A 24Vdc (I would have preferred 36Vdc) was sourced and its mounting location determined. there isn't a lot of space so i had to mount it in the wire feed side.<br />
<br />

The PM was also squeezed into a tight location. The plate it mounts to was originally inverted and covers other pots and switches.<br />

<br />
<br />
The torch trigger now activates a relay supplied by the 24Vdc. The relay triggers the original torch input on one set of contacts while the other are supplied from the output of the PWM card. This allows the wire feed to operate independent to the original fault but also keeps the gas and welding current control as original.<br />

<br />
A friend of mine owns one and as I was bored and he wasn't using it he brought it over for some lookin.<br />
<br />
There are a few documented mods that they are treated to as can be found on mig-welding.co.uk forum <a href="http://www.mig-welding.co.uk/forum/index.php" target="_blank">mig-welding.co.uk/forum</a><br />
<br />
To Robs mig i added a 1.5A 24dc power supply as a dedicated wire feed. this would stop the feed stepping up with the welding voltage and varying under load. <br />
<br />
<br />

<tr><td class="tr-caption" style="text-align: center;">lifted from mig-welding.co.uk</td></tr>
</tbody></table>
<br />
<br />
Also a relay to trigger it was connected to operate simultaneously with the welding current transformer. This is also arranged in such a way to short out the motor to stop it dead, over-running being oner of the little migs issues.I zip tied it to the heat sink on the card.<br />

Robs SIP has a metal feeder liner not the plastic one so that doesnt need upgrading. I would like to change the gas hose to accept a normal gas regulator and brace the wire feed rollers together as they do spread slightly when tensioning but Rob wants his mig back!<br />
<br />
until the next one<br />

Blackened and horrible. But it still works so why fix it?<br />
Volt drop, that's why. The damage on the contact points are creating a high resistance and dropping your voltage at the weld.<br />
Welding is a Low-Voltage exercise anyway so dropping a couple of volts will affect your weld quality.<br />
<br />
Usually not a big deal with MMA (stick) but fluctuating voltages will cause issues with your Mig welding especially. Ever had you welder not weld the same even though the settings and material are the same?<br />
<br />
The effort spent cleaning the work piece is wasted if the clamp is this dirty.<br />
<br /><div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjEdlybwaSeqyNzhWvzby3MvK4oh2VaLYIPvYyRgtXS21SncGBj_DT1MJ3mNvHUlNA6uOrpVc3HnyM8mZejVf9UC18qbsE0Dg8CDttPbZOIWKaqhy5oGQmoOzBjn7nWbCWa4FHk9oU1HlTd/s1600/100_9357.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="300" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjEdlybwaSeqyNzhWvzby3MvK4oh2VaLYIPvYyRgtXS21SncGBj_DT1MJ3mNvHUlNA6uOrpVc3HnyM8mZejVf9UC18qbsE0Dg8CDttPbZOIWKaqhy5oGQmoOzBjn7nWbCWa4FHk9oU1HlTd/s400/100_9357.JPG" width="400" /></a></div>
<br />
In this case also the lug connection on the clamp end is slightly loose and corroding as is the cable.<br />
The Dinse plug on the end is very worn and will also result in the voltage drop mentioned earlier.<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgCo23W4LMUksARzzTOWM812aC3-ZRtaaLVmYFkWg7h6m0fHcoQ4FKz023mSgGUcCgain8hQd46GoVNPYDZ-mgOM2wlgXEySTE2Md7o3wRg-zypkR-4THD0sFFubaIXSYO02DQioXZF9JKM/s1600/100_9353.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="320" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgCo23W4LMUksARzzTOWM812aC3-ZRtaaLVmYFkWg7h6m0fHcoQ4FKz023mSgGUcCgain8hQd46GoVNPYDZ-mgOM2wlgXEySTE2Md7o3wRg-zypkR-4THD0sFFubaIXSYO02DQioXZF9JKM/s320/100_9353.JPG" width="240" /></a></div>
<br />
<br />
<br />
This is now 3 points on one lead that have a drop. It ads up and can affect your finished weld. Its also likely that the torch end has enough problems to overcome without the earth adding to them.<br />
<br />
In short, keep your connections tight and your contacts clean.<br />
<br />

The tube arrived in the post today. Plugged it into the base and........... it works.<br />
<br />
Was hoping for something more exciting I suppose. Just bought a $300 amp for $60.<br />
<br />
The volume potentiometer is bad though and a few others too so I'll replace them in time.<br />
<br />
A pic of the two tubes. The pink Lines mark points in the Glass where a blackening is on the old but not the new. They are both 12ax7 tubes. <br />

A previous repair job has been done. The components (high wattage resisters) all seem fine, this may not be my issue but definately has me scratching my head on how to get around this.<br />
<br />
Have dug up, on the <a href="http://www.drtube.com/marshall.htm" target="_blank">Dr Tube</a> website, the schematics for a JCM800 series 50watt amp running a 12inch speaker.<br />
Thats my new worst case scenario plan Triker Chewiehttp://www.blogger.com/profile/06471979794450206695noreply@blogger.com0tag:blogger.com,1999:blog-7824637913659100349.post-25261188832870388562013-02-06T22:33:00.000+08:002013-02-12T12:54:48.343+08:00Marshall Valvestate 8080And now for something completely different.<br />
Having recently sold my huge guitar amp i needed a smaller alternative.<br />
Having basically wasted a pile of money on the huge amp in the first place, the subsequent sale left me needing something cheap.<br />
Up popped this nifty 80watt combo for low-low dollars.<br />
One catch.<br />
It doesn't work.<br />
<br />
<br />
YAY. Two needs filled.<br />
Didn't even waste time chatting too much with the guy, just dropped him 2 lobsters (Aussie slang) and dragged it home.<br />
Plugged it in and sure nuff, don't work. Some weak output and crackling when the master vol is turned. <br />
At this stage I've ordered a replacement preamp tube. It only has one so i figure for $20 its a worthwhile spare anyhow.<br />
Also downloaded and printed the schematic from <a href="http://www.drtube.com/marshall.htm" target="_blank">Dr Tube</a> so safety net in place!<br />
<br />
A welcome change from the Mig welders as all they have needed was reassembly and parts replacement. This is my first foray into Amplifiers and hopefully I don't Fuck it up completely.<br />

It's a vertical/horizontal unit and it does what I need it to do.<br />

One thing I always hated was the Phillips screws that held in the table. Never could get a screwdriver in straight enough to put enough torque on them. The table wobbled and the heads stripped after only a few uses. <br />

Much tighter, more stable and I'm actually happy to use the existing table when I need that kind of thing.<br />
<br />
Just shows how a small mod can make a huge difference to a machine!<br />
<br />
<br />
Another thing I did to this bansaw was to connect a socket to the output so I could run a vacuum cleaner while its running and stop it when it stops.<br />
I use it to cut wood and plastic at times and the constant running Vac was annoying.<br />

When i picked it up, the guy said he never had it plugged in(!) but was told it wouldn't adjust wire speed.<br />
I plugged it in and indeed any speed you wanted so long as it was full speed.<br />
A little metering and the potentiometer was the culprit.<br />
Bought 2 replacements for $10 and now it is regulating wonderfully.<br />
<br />
Then it soured. The gas line to the handpiece has perished and the control cable has broken as well.<br />
The unit is a push pull type with a feeder built into the handpiece.<br />
I need to find some options on the hose type.probably just blg some air line from work.<br />
<br />
I do have a spare tweco gun and wirefeeder but i like the push pull thing.

had a bloke arrange to meet me yesterday arvo to buy one of my welders.<br />
spent a couple of hours getting a space and a bit of steel ready so he could try it out<br />
the time came- no show.<br />
waited, cursing, for him to at least call.<br />
NOTHING<br />
is it so hard to ring and let me know?<br />
this isnt the first time its happened. must be three or four wankers who have wasted my time and several of my friends have had similar experiances. it isnt that bloody har dto send a text, is it?<br />
jokes on them. i work nights and someting round 2 am on a wednesday i'll make my call- from a blocked number of course<br />

My budd Tom picked up his mig the otherday so I'm down to 6 migs<br />
2 fully functional- awaiting sale<br />
1 being repaired- keeping this one<br />
1 awaiting repairs- for sale<br />
1 missing a lot of parts, switches etc. will have to see how we go<br />
and 1 hasnt made it all the way into the workshop.<br />
these should all keep me out of trouble for a while. hopefully i can get you fellers some blog fodder!<br />

Basically I am sad enough to fix things at work and at home<br />
While stripping and repairing the mass-o-migs I have, I found this.<br />
<div class="separator" style="clear: both; text-align: center;">

<br />
<br />
The pitting was caused by the nuts being loose on the stud. The nuts were holding the lug supplying current to the mig gun.<br />
A bad joint here has caused arcing and damage to the threads.<br />
<br />
Best result of this is a loss of weld quality. Worst case- fire<br />
<br />
I have been sanding all contacts smooth and tightening them to effing tight.<br />
These connections are usually in a location that the user can get to and check.<br />
A little care and they will last a lot longer. I can't help but wonder if this was part of the reason these welders were offloaded in the first place.<br />
by the end of today one more will be functioning. Resurrected <br />

my old Safmig 180 has a minor issue that needs sorting before i sell it.<br />
the hobart seems to need a new pot then it's cooking.<br />
ive got 4 porta mig 300's that are a little sorry. will be a real hunt to fix them up<br />
and a mig-o-mag 300A in unknown condition.<br />
things have been slow as far as Blog fodder but these migs need fixin and sellin so i'd better yank my finger right out<br />

They didn't work and were heading to the bin.<br />
<br />
The drill press also had a broken casting where the work table clamps to the mast but that will be repaired for a different blog. The drill press was old and unloved and the company had bought a new one. The cost to get the bench grinder repaired professionally was 95% of its replacement cost. Love our throw-away society. <br />
<br />
Both had the same electrical problem. Flick the switch and..... a hum a wobble but they spin up to full whack when spun by hand. <br />
They both needed the Capacitor changed. The price of a new cap is maybe 10% of a new motor so even if the motor is knackered still, its worth trying the cap. <br />

Most bench grinders are of similar construction. All the electrics are in the base with the switch. Be sure its unplugged, mains voltages can kill. Lay it on its back. With the base off it may look a little like this.<br />

The white cylinder is the capacitor. It may be grey black or blue but they are all cylindrical. With luck it will still be legible. A lot of the time it will have burst with the top or bottom expanded out the end. If you've been ignoring it for a while it may be burned to a crisp.<br />

The grinder had the rating quite clearly on the side so i replaced it with like but the drill had been used for years with the cap out so it was crispy.<br />
Capacitors must be correctly Sized for the motor. Also the may be cap start/run or just cap start. <br />
Grinders are always cap start/run and the caps must be rated correctly for that duty.<br />
<br />
My drill is cap start only. I determined this buy powering up the motor, spinning the chuck by hand to start is and then turning off the power. There was an audible "click" from the motor, that's the centrifugal switch operating. This means that you motor switches in and out the cap as required. no click may mean the switch is knackered but most likely is Cap start/run.<br />
As i had no rating to guide me i used the following table to find the appropriate size for the motor.<br />
<br />

<br />
<br />
Don't fret if you cant get the exact replacement rating, as close as possible is ok. The cap on a pillar drill is usually in a housing on the side of the drill. Again, mine was missing but here's an example from my smaller press.<br />

Once you've installed the new cap, put it all together and fire it up. Be careful though.remember not to spin the chuck anymore!!!!!Triker Chewiehttp://www.blogger.com/profile/06471979794450206695noreply@blogger.com3tag:blogger.com,1999:blog-7824637913659100349.post-62021080973622089892012-05-01T05:09:00.002+08:002012-05-01T05:09:44.142+08:00Just a brief one today.

Previous owner said it simply "stopped" and needed a new "card."<br />

This is the burned component that fell off the card.<br />

I googled about and found the AUD90 (!!!!!) replacement card. when i stood back up i had a re-google and saw that the burned component was the only part that ever failed. It was very consistently asked about on welding forums.It is a wire-wound resister, they fail quite commonly in a lot of DC-DC power supplies <br />
I used a Jewellers eyepiece to read the rating (3.3ohms and 7watts)and was ecstatic to find that the component was locally available for AUD1.80. A nice little saving.<br />

I actually got a 10watt as it takes more heat. The repaired card (below) was whacked into the mig and now sweeps through its range and at all power settings.<br />

A little note, even the higher wattage resister is getting too hot to touch while welding, it obviously is heavily loaded so I can see why the original would burn with prolonged welding. Allowing it to cool between short welds would be prudent.<br />
Most of the smaller "hobby" migs are very similar inside. The resister is a different rating from make to make but the principals are the same.<br />
Hope this helps somebody, in all I've got about an hours repair time in it and a couple of hours search time. Thanks to Lilly, my assistant<br />

That's the name given to my backyard workshop where i do my thing.<br />
Inspired by the plethora of blogs and websites made by amateurs and professionals, Ii have decided to share the things i have learnt and hopefully help others like i have been helped.<br />
I am an Australian and hope that any international visitors to my Blog will understand that laws and practises vary from country to country.<br />
I am an Electrician by Trade and have experience in both maintenance and installation work, domestic, commercial and industrial.<br />
Most of what i post will be me fixing things that others have deemed too far gone. Usually when an appliance or tool has stopped working it is considered (often correctly) that it is too expensive to have it professionally repaired. i have been lucky to have received a few quality tools that have stopped working and were on there way to the bin.<br />
I'll update this blog from time to time with tool repairs or upgrades and also a few automotive projects that i am involved in.<br />
Hope you enjoy my ranting and attempts and infotainment!<br />
