Yet another stainless question

by Chuck Meyer

Ive already picked up a lot of good information from your site
but i still have two dilemmas... one is a paste flux adequate for shielding the back of a 300 series repair ??

or should shield gas also
be applied. and hf or dc power be used?



Argon gas shielding is the way to go on stainless.
solar flux paste is a mess.

DC electrode negative is the ticket.

you dont absolutely need hf high frequency start, but it helps.

high freq is great to have , but if you already have a tig machine with lift arc or scratch start, you can probably get by. unless its really thin stainless sheet.
