I have an old ESAB LAG315 MIG/MAG welder from the 80's. I was wondering if it is possible to use spray transfer on it. I'm using 1,0mm wire (~0,04") and argon with 18% co2. What kind of setting should I use?

Also I've been wondering about the relationship between voltage and current. Why do some newer machines adjust current and older machines adjust ampreage? On my machine, I guess, the voltage will increase when I turn up the current?

Thanks!!

Can your machine get into the high twenties for volts? I've read where guys say you can get into spray faster with 98% argon, and 2% oxygen.

This is .035” Lincoln's L-56 wire with C-10 gas.

There is no way to tell how many volts it's putting out! It only has current switches on the front panel and a separate wire feeder unit. No digital meters on my welder . If it's necessary to know the voltage, maybe I could measure it on a separate device between + and -? That way I could learn how to adjust the voltage?

That's a beautiful bead!!

That works, just have someone read the meter while you are welding so you can keep a consistent bead and reduce the minor fluctuations that show on the meter.

Or just video the meter and play it back when finished.

Crank it up into the higher settings and then adjust the wire feed to suit, until you get a sound like cloth tearing.
