    Purging the TIG torch

    I was trying to do a little TIG today. Turned gas on, pressed the button to get flow and set the regulator. I think it's set for about 2 seconds of pre-flow. When I first hit the peddle, the tungsten turned black and blew a piece of the thin steel away. Kinda like when one forgets to turn on the gas, but not as bad. I touched up the tungsten, ran a little more argon and all was well, except for my TIG welding - but that's another issue.

    I rarely use the TIG welder. I think the last time was March. When sitting this long, should I purge the torch first? Thanks for any insights.

    before I start welding (still in practicing) ill hit the foot pedal once or twice to purge the line of air to get argon to the tig torch before actually welding...

    Re: Purging the TIG torch

    I always run argon through it before starting to weld. Even if the machine doesn't have a pre flow adjustment at all you can just turn the post flow up a bit and bump the pedal once or twice. Im pretty lucky in that Everlast machines have a "gas" button that allows you to run the gas for however long while you set the flowmeter and that will purge the line.

    ALSO, when doing just normal welding, I always have my preflow set to 1 - 1.2 seconds. Seems like when doing this i get a real crispy pop like start every time because it gets the entire weld area shielded with argon. Try it, you will like it i promise.

    Guys, thanks for the tips. I'll be sure and purge the torch, especially after it sits idle for 6 months.
