Welding Tips and Tricks

Hi all. I am new to the forum and tig welding. I have been learning mostly from watching YouTube. I bought a used tig welder that came with various filler wire. Some of the wire is for stainless but has no markings. How do I tell what type of stainless wire it is? Thanks for your help.

If it's not stamped or flag tagged then you won't know. Unless you have access to a Positive Material Identification (PMI) gun, which are very expensive. http://alloytester.com/s1-titan

Thanks for the reply. I think I will just buy some new rods.

Just use them for practice on mild steel and 304, 304 will dilute most stainless filler enough that it should be fine if it's not used in a critical application.
