electrode size, type
travel speed
preheat
problems to look for
polarity
amperage

Not sure what an A36 44W is? If it is a normal carbon manganese steel welded to a 304/316 type austenitic, then you will need an over-alloyed consumable to allow for dilution, such as 309.

Stainless steel is a poor conductor of heat, therefore less amps is normally required. Protection of the root either by material or gas backing is recommended, unless the process contains a flux (such as Stick Welding)

There is a good article on the welding metallurgy of Austenitic stainless steel in

Another site you may find useful is the 'WELD POOL' not sure of its address but there is a link to it form gowelding..

Another source of good advice is your consumable supply/manufacturer.

If you require further assistance I would suggest you supply more details.
