Titanium Question

[Craigs]

I used the search option before posting this.

For your common alloys I typically use 1 amp per .001" of base material. Is this true also of Titanium?
I have read alot about argon flow and how too much can contaminate the weld by drawing in impurities and oxygen. Is there a general rule of thumb to follow for selecting the correct flow rating?

Also, does anyone have any good images of homemade trailing shields? Before I spend $700.00 to $800.00 on one i'd like to try one out to see the full benefits.

Thanks in advance for any help and advise,

Please don't tell me you'd use 125 amps to weld on .125 stainless steel.

Look real good at some of the store bought trailing rigs and use there basic ideas as your own. I've seen some nice ones made from very thin ss sheet metal stuffed with steel or copper wool.

Yeah I should probably have mentioned that I use this theory for CM and mild steel.
I also forgot to mention that I am using a gas lens

I've also seen some trailing rigs with porous copper in them. Yes a gas lense is a must with Ti.

huge gas lens and cup as well as a trailing purge and back purge, or an argon chamber.

can someone help with the amperage question?

[Showdog75]

Ti amperage wise will weld more like stainless. Start on the colder side of amperage setting and work your way up to what you need. You can burn up[ruin] Ti just like you can stainless. Btw what are you welding thats Ti ?
