SIP migmate mods

The SIP migmate series of welders are/were an affordable mig but they suffered from a terrible wire feed.

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.


lifted from mig-welding.co.uk


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.

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

  1. Can you still control the wire feed speed with the dial on the front of the welder wit this mod?

    I also have a SIP 130 with poor wire feed, and will be doing this mod soon!
