Found itI would also use a bigger ceramic, and have less stickout, and around 8 or 10 seconds of post flow. and around 8 to 10 lpm gas flow, check that at the torch with a peashooter.
I just managed to split my tungsten down the middle for about 4" how is that possible
It happens to some tungstens when they've overheated and heavily contaminated. e.g. white hot 2.4 tungsten at 200 amps - if you badly dip it, it will suck up a load of alloy, if you keep going at all it can crack, and the longer you keep going, the bigger the crack. Sometimes its a small dip that you just keep going on.I just managed to split my tungsten down the middle for about 4" how is that possible
2.4 mill gold also tried blue grey and red
150 amps max 30% balance
70 Herts
Pure argon

the dial / scale on R Tech machines reads the other wayarc balance needs to be between 70-80
try arcing up on a piece of cooper arc balanxe turned right down, it will smooth and round the tip off just nice
Good you got to the problem I run a #5 cup on just about everything very little stick out I only go to a bigger cup when I get near the 200amp markFound it
Seal on back cap
Put a new bigger ceramic on as well
10 LPM always do
Different animal now
I wish I had stopped and sorted it out instead of pressing on
First alloy job for a while .
Steel must be more forgiving
