stainless

[catdr]

I jumped into welding about two months ago and bought a syncrowave 250, and started practicing, my alu welding has progressed awsome, in fact i just did a soda can this morning. unfortunately stainless isnt going so well. pool builds fine then arc starts spitting a little, if i add filler it spits horrible! welds look overheated/charred im not using much current just enough to build the pool and maintain it. What am i doing wrong????

what are your settings and the thickness of the SS ??
i want to say its a lack of gas isue. back gassing is a must with thin stuff. i usualy up my flow a bit and increase my post flow for SS and use a bit larger cup ( usualy a gas saver with the clear cup) i get good coverage that way. a gas lens would also be good, but you should be able to do it fine with a standerd TIG setup. i'm still fairly new at TIG but thease things have worked well for me.

overheating? wrong rod?

Well lets try the basics...Is the tungsten prepared correctly,and not contaminated?
Is the s.s clean?

well at least i can stick to one tungsten, its always 2% lanthanated.
