I just have a 110V miller mig welder. I use .030 wire, old box says 70S-6. No clue what that means. But if I type that into the web there is multiple brands of it on Amazon. I'm sure all from China. Is wire all the same? My box is from Linde, Prostar brand but even in their fine print made in Canada using foreign parts.
I'm not a great welder by any means. Good on a good day.
Heres what I've learned over the years to add to the other great recommendations:
1. Don't buy a big spool if you aren't welding very often. I have so2 or 3# specialty rolls in the cart, a 10# roll is enough for quite a while.
2. Reason for the roll size: unless you're humidity conditions are perfect, you can get rust on the wire. You don't want rust on the wire, it'll ruin your day.
3. I equated foreign wire with rusty wire, only because I had a terrible time with it. Our local supplier bought a lot of wire cheap, and was selling it cheap. Compared to Lincoln, esab, or Hobart for example. I couldn't make the welder work, thought it was me. Buddy stopped in one night who welds a lot. He'd bought like 5 or 6 rolls from the same place I did. Only he discovered the rusty wire right away. It wasn't a good day for the supplier when he took it back. He got all his welding supplies and gas from them, and offered to go elsewhere if he ever had to deal with that problem again. Anyway, I've never had issues with the 3 wires I mentioned.
4. I like the little foam cleaner thingies you clamp on the wire between the roll and the feed rollers. I think they help keep the rollers and liner cleaner and working better.
