wide etching on aluminum

[johnson697]

Yes it did ball up,and yes i do have the ex.Had my amps around 180,but not sure how much i was actually using while i was welding but i would guess around 110 to 130 amps because i was only using a little over half of my pedal while i was welding .Had a guy i work with tell me to take off the gas lens and use a standard lens ,gonna try that tommorrow.

The gas lens has nothing to do with etching.

anyone welding for 12 years and claiming to have welded some of the fuel tanks shown in the photos would know that.

i am using both lanthanated 1.5% and also thoriated ,but try to stay with the lanthanated for my aluminum ,and i dont ball my tungsten up.

Thoriated won't ball either, if it's less than 40%, which is where it should be located at anyway.
