So it's hard to tell where I started because I was all over the place trying different things so I'm sorry for it being confusing. I started out not using any filler rod and then moved on up after I felt I could move the pool around. This is all using a LE TIG 175 with 100% Argon at about 13cfm and started with roughly 45amps and eventually moved up to around 65-68amps all on 1/8" steel body panel. Any advice is welcomed and thanks in advance.
Reply:Apms are too low for 1/8" steel. Set the machine for around 125 amps if you have a pedal, and roughly 90-100 amps without one.The blobby bead looking weld on the left looks like you were melting the filler with the arc. You want to melt the filler with the puddle..No government ever voluntarily reduces itself in size. Government programs, once launched, never disappear.

Reply:Yeah I kept having the filler end stick to the weld and was moving the arc on it to melt it off. I'm guessing that was happening because the amps were too low also?

Reply:Yes that's very typical of what happens when you are not using enough amps..No government ever voluntarily reduces itself in size. Government programs, once launched, never disappear.

Reply:Sorry I didn't state that earlier. I am using 3/32 filler and same for 2% Tungsten. Going to practice more today. Thanks for the tips.
Reply:IMO, the filler rod is too thick. It's only 1/32" thinner than the material. What this results in, is that it ends up sucking much head out of a puddle that was already very cold to begin with. Try 1/16" filler rod. You'll find it "sticks" less to the puddle/base material than 3/32" and will be much easier to feed. 1st on WeldingWeb to have a scrolling sig!

Reply:Careful, it will all happen faster when you get the amps right. Learn to back off the pedal to keep your heat even. Attached ImagesSqWave 200Millermatic 190Airco 200 ACHypertherm PM45Boice-Crane Band SawVictor O/A

Reply:@ MacsGTO - set factors for 1/8" material,* 100A for stainless steel* 125A for mild steel* 150A for Aluminum As DSW stated, too cold = no good. Need enuff HEAT to form/maintain the puddle, as it's the puddle, not the electrode, that you want to melt the filler. Key point. No expert here....personal experiences based on formal training and many:many practice sessions. Even though you are rip'n autogenous (ie. not using filler matl), the above baseline amperage settings still apply. Modulate your amperage according to how the fluid puddle is behaving.Watch the puddle and modify your behavior (ie. amperage to torch) accordingly. Also, think straight and linear for now. Run the beads in a horizontal line w/ intent. Do not be in a rush to "finish". Zen Ops.Best fortune with your TIG journey....Last edited by ManoKai; 04-10-2013 at 10:36 PM."Discovery is to see what everybody else has seen, and to think what nobody else has thought" - Albert Szent-Gyorgyi
