AHP says they are sending me a pre-paid shipping label but that was first thing friday and i havent heard back on it yet. Hopefully they will let me know what they find.

Re: Erratic arc

I know I am new, but this sounds just like what I did last weekend when I installed the stubby gas lens kit. When you installed the collet in the collet body did you put the slit end in first? I put mine in with the slits up toward the cap and it did the same thing. Arc would jump all over the plac...

Re: Erratic arc

Update for anyone who might be interested... no obstruction was found in the gas lines or regulator. The argon solenoid isnt a type that looks easily rebuildable so i didnt take it apart with the machine being so new. The screen on the inlet of the solenoid is clear though. The argon tube inside the...

Re: Erratic arc

I think it's safe to say in this discussion that gas is the culprit... I myself doubt the insulator makes any difference at all, and having too much gas flow is a good thought but I doubt that too as it would have to be an awful lot of gas to blow itself out that consistently I would think (?). But...

Re: Erratic arc

If the problem only started with fitting a gas lens can we see a picture of how you have it fitted ? unless you managed to find the elusive 1piece teflon insulator you fit the one in the gas lens kit WITH the original otherwise there will be a gap where it meets the torch body & atmosphere will...

I have put a sharpened 3/32 stainless rod in place of tungsten once, it just made a mess of everything. Go figure.
Just to be safe i did double check and ive got the blue stripe on the end still.

Re: Erratic arc

Thanks for all the ideas so far guys. I remived the torch body from the line and i can easily blow through the torch body and the torch hose with my mouth. The flared connection where the torch nut threads onto the hose looks perfect. I dont have any friends who mess with tig at all so im alone on t...

Re: Erratic arc

it looks and sounds like you're set on AC instead of DC. If it makes a bunch of crackling noise, it's probably on AC... You shouldn't hear anything if you're set to DC. Maybe your welder is wired up wrong, try switching to AC and see what happens. how's your ground clamp? put the clamp directly on ...

Re: Erratic arc

While I do identify myself as a mechanic and I'm always tempted to put stuff on threads I have not dne anything like that here. I'll take the torch apart more tonight to see what else I can look at. I'll also try a new standard colllet and body when I get them. The only flow meter I have is on the b...

Re: Erratic arc

I dont have a new collett and body to try right now but ill pick some up. I have tried using the damaged ones i have with the exact same result. I was at 20cfh and turned it up to 30 to see what would happen but i didnt notice any difference. I did check that i was still on dc becasue how its affect...

Ive got an ahp alphatig, using the footpedal. Things were progressing along to my satisfaction just welding mil...
