Hello,
I have to do a certification test on 1/4 and 3/8 aluminum. But I'm having trouble getting penetration in the corner of my fillet. I'm using a miller square wave 250 at 200amp with blueshield 2 gas. And I've going between a 3/32 and a 1/8 tungsten. I tried upping the amps ,but then I blow apart the tungsten or the cup. Top and bottom are good penetration , its the damn corner. just not enough. This the first time in years I've tried to do this and its pissing me off I can't get it.
Please help.
I didn't find the right solution from the internet.
