A friend of mine owns one and as I was bored and he wasn't using it he brought it over for some lookin.
There are a few documented mods that they are treated to as can be found on mig-welding.co.uk forum mig-welding.co.uk/forum
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.

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.

after
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!
until the next one
