Hi, just bought a 2nd hand sip 170 mig welder. I obviously assumed wrongly (based on the current new selling price of around £450) that this was a decent welder, but having read through these forums that was obviously a mistake :-(
I'm not sure how old it is, but in its favour it does have a euro torch.
The main issue I see is the wire feed control, and I'm just trying to get my head around the best modification (of the many posted) to use.
Mechanically I will make the brace to stop the wire feed rollers pushing apart on the plastic spindle.
Electrically I'm not keen initially on adding a seperate power supply to run the motor (at the moment at least), so looking at the 2 options to stabilise the voltage - one being in this thread http://www.mig-welding.co.uk/forum/showthread.php?t=17892 (using capacitors and relay) and the other being in this thread http://www.mig-welding.co.uk/forum/showthread.php?t=9206&page=3 (using a mosfet and capacitor).
Any opinons as to which is the best solution ?
