as long as your power lead or torch is not leaking, you are fine as frog hair.

been there, done that, got the hat.

Bet that didn't take long...
Seconds. It did not smell good, either.

Looks like that got hot in a hurry Otto! :shock: Luckily my machine was set for about half of that!

3 sec at 200A AC without water was enuogh to melt the water hose. Power hose made it so it was just to cut off an inch and it was fit for fight again :roll:

All I know is that I wouldn't want to to anything to ruin a water cooled torch. I learned on a 17 and then went to a water cooled for a few months at a local tech school (not a ton of hours but enough). I came back now and burn my hand everyday running from 120-180 amps almost non-stop. I have to stop after a half an hour so I don't burn my hands all the time.
A student now but really want to weld everyday. Want to learn everything about everything. Want to become a knower of all and master of none.

Yah, I hear ya! When I bought my first Tig welder I bought a air cooled torch to save on $ and they do get hot!!

how that turns out....

Craig, 1 word buddy WIRELESS...lol I love my wireless pedal as I find myself trapping the damn cord at times on the wired pedal we have on the main shop welders as I move it around the table. Getting it under a stool leg is popular for me too...lol
I weld stainless, stainless and more stainless...Food Industry, sanitary process piping, vessels, whatever is needed, I like to make stuff.

Unless your machine has no way to change foot pedals with that style connection and only accepts Ethernet cable ends and doesn't allow you to easily replace torches or stick weld (Miller diversion 180 he says while coughing)

Pete, I should have mentioned it was AC welding, so tons of heat in the torch, lead, and coolant already. The steam looked like smoke (and there was smoke from the burned hose), and someone ran up and killed the disconnect at my power outlet PDQ. I was doing a long 1/2" aluminum 4G from a creeper, and rolled a wheel over the supply line, and "poof", all gone.

I was doing 1/4 or 3/16" 3003 diamond plate once, blasting my welder for hooooooours. Had to keep on stopping because the torch got too hot. Ended up grabbing a bucket of cold water and I would dip the torch it in, worked just about once :lol:

Must be kind of hard on those alumina cups, I'd think... :shock:

Yeah, didn't work out too well, contaminated the living hell out of my hoses too. Split the taperered part of the cup right in half.
