Hi
I recently bought a sip mini 130 synergic after having an old sip migmate 130 for about 30+ years. On a recent weld job on my car I seem to be blowing a lot of holes in the weld, I can see the current is obviously too high, you can see the edges I'm trying to join retreat away from each other, I've had cut the repair hole quite far back from the rusty bit to make sure I'm not welding weakened metal, some bits are ok but some of the metal, even the good stuff is paper thin.
I think the thing I'm struggling a bit with is the synergy control. The book says start with it in the middle i.e. 0% and current at 1, which is a ball hair off the bottom of the dial. I never really understood this synergy control and really preferred my old mig, which had the range of manual power settings.
At the setting I described it seemed like the feed speed was too quick sometimes then when you try to adapt it slows down and then you slow down and then burn a hole through. I tried my best to weld away from the weld to minimise heat build up but it still doing this burn through.
Any thoughts on settings or how to try and lower the current flow? I was toying with the idea of getting a welder with a lower current like the autostar but not sure if it might be something else I can try.
I'm using 0.8 flux and MIG welding and using 0.9 zinc coated steel for repairs. I read that 0.6mm wire is perhaps better for that thickness?
Thanks
Andy
