Repair / Re: Mig welder wire feeder controller board not working
« Last post by .RC. on Today at 03:21:13 am »Yeah, basic, non critical MIG welding on mild steel is pretty forgiving. I never really understood why some people end up with no penetration on their bird-poop welds....
I actually found it hard to do a bird poo weld with a mig. What it is easy to do it do a visually fantastic looking weld that has zero fusion to one side. I have also found cold mig welds on commercially made stuff.
Mig welders because they are more complex to get the settings right, with volts and wire feed and gas type or gasless or dual shield has opened a whole new level of crap welds. At least a stick weld looks crap if it is crap and starting out stick welding I did a lot of crap welds.
The old days your 15a socket melting (yes I melted a few of them) AC transformer stick welder had one knob to adjust (well some were flash and had 2 OCV settings), and everyone was running 6013 rods. Life was simple.
Of course one quirk for Australia that has gone full short bus on regulations. Dodgy Darryl at his home with his $150 mig welder and a roll of flux core and ten minutes welding experience can weld up a trailer to tow behind his car and get it registered no problems at all.
