Trying to weld, I’m terrible!

If you switch to 0.23 wire, you will have to switch to 0.23 tips and a 0.23 liner.

On my Millermatic 211, .023 just requires roller and tip change. Liner stays the same for .023 and .035.

My floor welds are Fugly as heck....good thing there's carpet covering them lol.

practise on scrap metal till you get better at it...

Yep the fumes are a bish, maybe the argon to possibly displacing the oxygen I needed to breathe. Yesterday I welded some old cast aluminum valve covers that a customer mutilated, I felt bold and told him I could do it.
4032 plate welded to cast, the welded the die cast breathers....it turned into a nightmare, I did get it done but I think I had some exposure to bad fumes, I went to bed early and got up late with a hell of a headache.

Maybe like if welding galvanized, drink some milk!???? Dunno!

Same on my Hobart, or I’m doing it wrong. Makes sense though since Hobart is owned by Miller and I think the tips are same.

Practice on scrap, a lot of practice. You may have better luck with the tip at a 45 degree angle to the floor to keep the heat from getting to hot in the sheet metal.

YES! Practice, practice, practice. It will come. Practicing on scrap allows playing with settings too.

The local welding store, where I get my gas, said I needed to change my liner. Maybe I'll call Miller. Thanks!

Correction.....Mine is a Millermatic 210 (if that matters)

I routinely switch between wire gauges while using the same liner. Mig wire has a helix designed into it so it is always in contact with the liner as it advances.......At least that's what I was taught at Mig school.

Breathing in Zink fumes will F you up.
I remember way back ,I used to smoke cigarettes, and after welding on galvanized steel, light up a cigarette and it tastes real sweet. Real close to Zink poisoning.

Couldn't hit the agree button hard enough. Back in tech school, we were putting in a new 600 amp distribution panel in the diesel shop at school and I was asked to weld the support crap into the galvanized box. Even after grinding aggressively to get through the coatings, that was the nastiest job I ever did. No respirator or anything like that back then of course. I would hold my breath, weld as long as I could and then jump out into fresh air. Stupid **** we did when we were nineteen.

As long as the liner is big enough to pass the wire your ok. The liner doesn't conduct the weld current to the wire the tip does. We rent out welding units all the time with 5/64 liners with customers running .045 wire without issue.
