MIG welding question

3/8" single pass running full tilt.

1/4" single pass continuous.

Ernie, thanks, you know everything, I appreciate your input. Would anything change if this welder could do, say, 48 volts at 200A? I am sorry if this question is wrong (if no one MIG welds at 48 volts)

what welder you looking at and what are you going to weld

48 volts is extremely high for wire feed. The only machines I have seen that can achieve that are big 500 amp power supplies for submerged arc welding (aka; sub-arc).

Thanks Ernie. 3/8" single pass at 36v is plenty for me. I suppose that I could do multiple passes in a very unlikely case if I need to ever weld more than that.

I got myself a Digimig wirefeed a little while ago to try with my new welding power supply (the old CyberTIG that I had that I modified to do CC and CV), I am reading its manual right now. Hence my question about mig welding. Have you ever seen Digimig wirefeeds? They are supposed to have a lot of bells and whistles.

What would be the most sensible MIG wire to try wirefeed welding first? Preferably fluxcore, as I do not have gas yet.

thanks

Never heard of one before.

The most common self-shielded flux-core is E71T-8. Lots of companies make wires that fit that spec, but the best I have personally used in ESAB Coreshield 8.

BTW "MIG" denotes a gas shielded solid wire like ER70S-6.
