FINALLY got my Everlast PowerPro 205 hooked up in my neighbor's basement, trying to weld his grill frame back together.
I'm having serious problems keeping the electrode from "disintegrating" back up the cup, and even broke one. I tried to just push through it to get some boogers down at least, but it's even melting to the cup.
Both with the gas lens that came with the torch, and a 3/32" I got in a kit, usually with the #4 cup (I broke the #7 lol). 3/32" and 1/16" tungstens both 2% lanthanated
And using 70S-2 filler (the right one for mild steel?) both 1/16" and 3/32"
Part of it I think was the shitty rusty mild steel from the old frame, I cleaned it pretty good on the outside but there's rust on the inside too, so I think when I get decent penetration I may be ruining the weld from that. But that still doesn't explain why the tungsten is getting fucked up. I'm pretty sure I used 2% lanthanated in my class and it never did anything like that.
This is at 50-70amps, barely enough heat to melt the 1/16" filler and I was putting holes in the metal.
It also looks like I don't have enough gas, but I was doing 3 seconds pre and post flow and using a LOT, like 50cfh. I thought I read like 15-20 would be enough (and probably would be if I was doing this right). But I never had to set up the gas in my class, it was all ready I just had to adjust the amperage and go.
But I never did anything this ugly in my class either:
What do you guys think?
