I have not used any SS arc rod, So i cant give you any personal real-world experience
help with it other than, Most Arc rod on the insert or on the front of the carton will give you a min an max heat range according to the diameter rod you are using.

Lincoln Excalibur 308/308L electrodes spec either DC+ or AC.

A quick look at one ESAB and one Hobart said the same.

I'm just a hobbyist when it comes to welding.

1/16" 316L - 16 rod
304 SS 5/8" tubing, 0.063 wall
About 50 amps DC+ with my HF toaster inverter welder.

Being thin I ran it cold and fast. regardless the rod burned faster than I expected did not see much, burned too fast.
I"m guessing AC would burn a little slower.

For me,
In the past SS rods melt fairly fast and fluidly compared to steel, may need to run them 5-10 amps lower than steel.

What are you welding?
What is the alloy of stainless?

Generally SMAW (stick) welding of stainless is done DC+ (Reverse Polarity),
but it is dependent on the rod you have purchased some will work DC+/-
and AC.

If you are welding something thin you might want to purchase some DC-
(straight polarity) to minimize heat input into the base.

I'm thinking about making a Habachi grill and figured I would use stainless for the top part where you would put the food. I was watching some videos recently. I have a Lincoln ac welder. Thanks

I have welded stainless steel salt spreader bodies up with an AC lincoln stick welder. They were generic rods that the shop manager had picked up so I can't help you with what to use, but it ran pretty easy. The puddle was a little runny, and the tendency to warp is a lot stronger so keep that in mind while you are working.


As an alternative, you can buy replacement grill grates at lowes and other box stores. I have used cast iron grill grates for a couple projects and they really don't get rusty if you rub a little oil on them and keep a lid over them. They don't have to be dry as long as they aren't in direct rain where it will wash the grease off.

Get yourself some AC rod, and practice on some scrap. You should be good to go.
