Try it a little different...

Try a lift arc method. Just touch the tungsten to the piece, pause and lift. A little practice and you'll get the hang of it. There's not as big a chance of contamination and more precise.

Glad it's working

You stand a better chance of contaminating the stainless. A trick I use is to lay your gun on the edge of your cup at quite an angle. Take your filler rod and lay it on the material and roll it to start the arc. Make sure you have the filler touching the material or you can get a jolt though...

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

Great to hear it...

Best of luck to you. Be sure to come back on and let us know how it goes. And pictures are always nice.

The raw answer to your question

Hi everyone!
I have a bobcat 225 welding machine,does anyone know if you can convert it
into welding tig with it
I already have e-mail miller co. twice and they haven't respond.
I do not want to have to buy a tig welding machine. $$$$
I also have a 251 mig,if i could convert it, which ever of them one or the
other.
P.S.Your comments will be appreciated

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!!!

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.)

Thanks alot for the info

[theweldor]

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.

for stainless

what do i ask for,the leads or a conversion box at my welding supply store?
I just want to tig weld stainless steel 1/8 thicke at the most.

[theweldor]

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.
