    You can use a tig on that machine. It will have a few limitations, maybe not quite as sweet as a high tech tig machine. I have ran them on many of my portables before.

    You will need a tig torch and cable with a gas valve built in the torch itself. There are several different styles. Some have a sliding valve some have a screw type valve similar to a torch valve. You will have what is called scratch tig as you will have to touch the material to start the arc. A little practice and it works rather well.You will need to run DCEN stainless and steel.

    if you are going to run a dry rig for any length of time, i found it's good to use a torch that will handle the amperage with no problem. i use a 250 weld craft flex head for 3/8 & up. i run inconel so, i use a higher amperage anyway. (i've melted a few necks.)

    In fact you don't need to do anything to your Bobcat to tig weld with it. You just need a tig rig to hook up to it. That would include the items listed above.

    I started tigging about a month or so ago with my gas-powered Miller. I bought a Tweco tig torch off of ebay, had a blown Victor flowmeter given to me and had it repaired, picked up a bottle of argon and protected my cables with a marvelous cover from http://stores.ebay.com/MJ-HOTcreations (thanks James and Mary). Total cost: $150. The stars really aligned for me on this one!

    Happy tigging!!!

    Default finally

    Hey everybody.
    I already got the tig hoses and argon.
    I finally started practicing .It came with three sizes of tungstens and cups.
    I practice with each of them until i got the hang on them.
    The only thing i didn't like is that i have to scratch it to get it start .
    I was useing 10 gauge stainless steel.I was cutting strips and fuseing them
    together and it works awesome.

    P.S. At first i was using a strip of copper to scratch,but then i got a little
    tire.Then i started scratching on the stainless steel.
    Will it contaminate the tungsten
