What causes black soot when trying to set up a spool gun?

I accidentally left my argon valve open and lost what was left in the tank. Does anyone make an electric shutoff? Thinking maybe hooking it up to the light switch or a timer.

I agree with this. There is no dishonesty is just giving the respected two weeks notice. It is not your problem if there are hard feelings.

Please post pics when completed.

I have a bunch of loose tungsten and need a tube of some sort to store them in......anyone have a suggestion?

Do you have to use pure tungsten on a transformer rig welder or can you use something else?

I have a Thermal Arc 186 Tin welder. For those of you that have the same or similar welder what setting do you use on the balance setting?

I need to buy some 2% 3/32 tungsten. Any recommendations.......any I should stay away from?

Two years ago I got a killer deal on a Husqvarna all wheel drive mower. Unfortunately this mower had no side discharge. I got tired of the mulching option clogging up and I hate bagging. I cut a square hole in the side of the mower leaving about a inch along the bottom if the mower deck to retain so...

If you are using a scratch start tig setup......no pedal.....no downslope. What is the proper way to end out a weld and avoid craters and such.

How do you find the appropriate amperage for tig welding stainless steel? It is so easy to get too hot......the weld turns black.......eventually rust will appear.

A little more specificity is in order. I am looking for alternatives to a wire wheel on a bench grinder.....but something that still goes on a bench grinder.

What are the alternatives to a wire wheel on a bench grinder? I have seen some form of Scotchbrite and flapwheels. I am looking for something that will last and won't break the bank.

I have several sections of railroad track I don't see myself using. They are free for the taking. I am not shipping these. I live in Pittsburgh Pa. PM me if interested.

Can bronze be welded? If so.....what do you use?

Can the same diamond wheel be used for sharpening tungsten used on aluminum and carbon/stainless steel?

Do you weld for long periods of time? If not seems like a minor concern as long as the tank is not leaking.

At work we have a welding table that all the mill scale over the years has all been removed. The reflection does not allow the sensitivity to be turned up in an auto dark helmet. Other than turning down the sensitivity is there anything than can be done to cut down on the reflection?

Inverter.

I am looking at some 2% Lanthanated tungsten. I see prices really vary. Are some better than others given all are 2% Lanthanated?

Ok......you can use a welder to thaw frozen pipes. What size machine so you need? AC or DC? What is the proper hookup and machine start sequence?

What exactly is a wild leg?

Would it be possible to just run a new dedicated line?

I read this thread 3 time till it hit me. You bought a Lincoln Squarewave 200 tig welder and after a few days of use it goes bad, ok it happens. You take it back and they sell you their demo unit and you take it back to the shop and hook it up to the same plug and blow it up. That tells me you have...

All my vice grips are Irwin brand. Good quality.......not a problem.

I have several tig welders all but one are inverters. I am sold on on inverters. But.......having seen what you went through I don't blame you for going the transformer route. You need to satisfy yourself and no one else.
