Melting Tungsten - New to TIG welding
 

Hello,

Trying my hand at TIG welding, and keep melting the Tungsten. Setup is
Dynasty 200DX with Coolmate, Water Cooled Torch, tried different
diameter electrodes, welding mild steel, setup according to manual
along with rod diameter selection, DCEN seting. The electrode always
melts before I can form a large enough pool to form the weld. Any
thoughts what I can be doing wrong?

Thanks,

Luds

Do you have the polarity backwards ?

Something is WAY wrong! Now, the very TIP of the electrode is supposed
to melt, just a little, when you are at the upper end of the current
range for that size. What electrodes are you using? Pure Tungsten
(EWP)? Those are only good for serious pros who are required to use
them in aerospace work. Get some Zirconiated electrodes for Aluminum,
and Thoriated or Lanthanated for mild steels. That makes a HUGE
difference.

Are you absolutely sure you have water flowing through the torch?
Are you absolutely sure the current control is working?
You should be using 100% Argon, and probably flowing 5-10 Cu Ft/Hr
for modest sized electrodes.

Do you have the polarity backwards ?
Martin

That would be my guess, too.

Harold

did you turn on the gas? do you have enough gas flow?

Check your gas. My supplier gave me a tank of 20% CO2/80% Argon. I had
blue fits trying to weld AL until I discovered the goof. It works fine
on steels.

What size electrode? What kind of electrode (pure tungsten, 2%
zirconiated, etc.) What current? What shielding gas? What flow rate?
What size filler rod? How thick is the metal you are welding?

I found that out..the same way I found out how to melt an
endmill....sigh

Chuckle!

An admission that you, like the rest of us, are perfectly normal? g
Don't ask.

Of course Harold. I dont walk on water, and I put my pants on one leg
at a time. I even manage to get the fly in the front most of the
time...

Front? The fly goes in front? ;-)
