    • Welding Stainless Steel: Expert MIG, TIG & Stick Tips I researched on how to weld stainless steel as i am welding stainless steel for a project and could use some advice from the pros here. i welded mild steel before with my MIG setup (using 75/25 argon/CO2 and ER70S-6 wire) but stainless seems like a whole different beast. i am also working with 304 stainless about 2mm thick for a small fabrication job, think brackets and a frame for a custom outdoor grill. According to my research and experts’ opinions, tig seems to be the go-to for clean welds on stainless but i also saw folks mention mig and even stick welding. Here’s where i am at: MIG Welding: Can I use my existing MIG welder for stainless? According to the experts i need stainless wire (like 308L or 309L) and a tri-mix gas (helium/argon/CO2) instead of my usual 75/25 mix. Is that true or can I get away with C25 for non-critical welds? What settings should i tweak for stainless? TIG Welding: i am tempted to try TIG for better control but I don’t have a TIG welder yet. Is it worth investing in one for this? What kind of filler rods and gas (pure argon?) should i look for? Also, any tips on avoiding warping since stainless seems prone to it? Stick Welding: i got an old stick welder lying around. can i make it work with stainless rods (like 308L)? or is this a bad idea for thin material? General Tips: What’s the deal with “sugaring” and how do I prevent it? Also, i saw a video that the stainless can rust at the weld if not done right, how do I avoid that? Any prep or cleanup tricks to make the welds look shiny and professional? i am not aiming for food-grade perfection here just strong, decent-looking welds that do not fall apart or rust too quickly. experts here got experience welding stainless to mild steel (for some parts of the frame), I’d love to hear about that too, do I need special rods like 309L? Would appreciate any stainless steel welding tips, recommendations or even machine suggestions if I need to upgrade thnaks in advance for the help
