Hey thanks do when helium pushes the ball tpo 20cfh in an argon flow meter its actually 60+ CFM of helium. now i know why the right mix of helium was just gettinhg the ball to lift half way to 5 cfm in the argon flow meter. Thank for the pics man!!!

Nice, glad to here you solved yout issue, So the gas lense does make a huge difference in welding apearence?

Ok no leaks.. i tried pure Helium at 10 cfh and couldnt get the arc started. so i increased the argon untill i was able to weld a decent bead.im guessing the reading on the flow meter im using for helium is throwing me off. So i just tune by weld appearence and argon flow. now what percent ratio wou...

ok so i need to go through all the fittings and put hose clamps instead of zip ties, and make sure the collet body is nice and tight. oh, im also welding outdoors by the way. I appreciate all of you guys helping me out here...

So the bead should be clean with helium in AC? Well on the hose barbs i have tir wraps not clamps, but i put water in each one and no bubbles, maybe a leak on the torch?

well you can just grind the contanibated section without breaking it, it works for me

just helium my weld looks black and filler ball up, welding helium

Hey ive got ur answer, the problem is that your welding just the pipe alone, last week i did a stainless job on thin piping and i was practicing on a thin piece of pipe like you, and the welds were gey also, i went crazy! when you add filler just trying to lay a beed on the pipe surface, 9 out of 10...

First of all, im new at this forum, my name is David and im from Miami FL. Nice to meet all you guys. Now, what the hell am i doing wrong? i have the "y" set up with 1 cylinder of Ar and 1 cylinder of He, Check valves, two Argon Regulators and a Miller diversion 180 on AC setting. When i t...
