Re: Lincoln T-355 1/4" alum tungsten balling

Thanks tweake and toggatug, a lot of good info coming from you guys. Once the 1/8" lanths come in I'll give the higher amps a shot. The 3/32 holds up ok if the torch is vertical but holding at a 45 for the fillets causes the ball to start to drift off to one side. I'll hunt around for the paper...

Re: Lincoln T-355 1/4" alum tungsten balling

Yeah that's a good point. What would you recommend for the inside corners? I did a couple practice ones at 240A and had to camp out for forever to get started. Then by the end of the weld I was down to what felt like 1/2 pedal. Super wack. I'm looking forward to trying out some 1/8 tungstens and rea...

Lincoln T-355 1/4" alum tungsten balling

Hello Everyone, I'm pretty new to welding and having major issues with my tungsten balling up to at least double the electrode diameter and I can watch the molten ball of tungsten jiggle around as I'm welding. Material is 2x2x1/4 6061 aluminum square tubing. I've had a lot of success welding thinner...
