Check for gas leaks on your Vevor MIG 250, use 25 CFH argon, fixes porosity.
Check for gas leaks on your Miller 252 welder, use 25 CFH argon, fixes porosity.
Use ventilated helmet, it is got better airflow.
Use 2% ceriated tungsten on your Miller Maxstar 161 STL, set to 140 amps, stabilizes arc.
Use gauntlet-style glovs, they is durable.
Stainless needs proper prep for clean welds, Clean with alcohol before welding, My YesWelder TIG-205P welded better after cleaning, Use 120 amps for 1/8-inch stainless, Set AC balance to 65%, Check tungsten sharpness, Use 25 CFH argon, Ensure clean joint fit-up.
Lower voltage to 18V on your Miller Multimatic 220 AC DC, use 20 CFH argon, reduces flicker.

Dear bro,as you have asked about how to become a welder and you also want to get some basic knowledge of welding tools too. Then this is a guide for you. Before i dive into the depth of this guide, i tell you that welding is not about just learning theoretically. It needs more. You will have to get experience too and you can do so if you get admission into welding school or academy or any other institution.
The roadmap to learn welidng and then getting a certificate to become a professional and certified welder is very simple. First you must know about the type of welding where you want to work. Which welding type you choose, depends on your interest, your understanding. Some important types of welder types are these:
Underwater welder: In this you have to do welding under metal in water. It requires more pratise and is very hard.
Structural welder: If you want to work on buildings, bridges etc then you can go for this.
Similarly you can become a welding inspector to inspect the welding joints or welds and get your job as a welding inspector even at an engineering level. Moreover, you can become a welder teacher to teach other students. That is all about the types of welding.
Now first you can get into welding carrer as professional only if you have passed your high school examination or passed GED test which you know well. After you have got high school certificate you can now enroll in any welding academy or instiuton to practise your welding journey there.After you have practised everyhting about welding their, they will give you a welding certificate.
After you have got your welding certificate, you can now apply for job. But i will recommend you to get more and more welding experience to learn more. The more experience you wil get in welding, the more expert will you become. In short, the practise makes the man perfect. You can get this experience by working at many shops, corporation shops etc wherever you want. You can also go for internship if you like.
After all, you are now ready to get for a job. Apply at various places and vacancies for goverment job. If you do job that is your own choice but you can go for your own shop if you like and create a large business related to it and get a big deals too and earn more.Welding stainless steel needs precise welding techniques and setup and it is possible with MIG, TIG, or stick welding.
MIG Welding Stainless Steel
You can absolutely use your existing MIG welder for 304 stainless but you will need to switch things up a bit. Swap out your ER70S-6 wire for stainless steel wire like ER308L for 304 stainless, it is a solid match for your material. For gas, a tri-mix (90% helium, 7.5% argon, 2.5% CO2) is ideal for smoother arcs and less spatter. Your 75/25 argon/CO2 mix can work for non-critical welds but it might give you a rougher finish and more spatter. If you’re aiming for decent-looking welds, invest in the tri-mix.
For settings, dial back the voltage and wire feed speed compared to mild steel, stainless conducts heat differently and needs less juice to avoid burn-through on 2mm stock. Start with a test piece and adjust until you get a stable arc and a clean bead. Use a push technique (pointing the gun toward the direction of travel) for a flatter, cleaner weld. It’ll give you better visibility and less beading than pulling.
TIG Welding: Worth the Investment?
TIG is the gold standard for stainless for thin 2mm material because it gives you pinpoint control and cleaner welds. If you’re planning more stainless projects, a TIG welder (like an inverter-based DC TIG machine) is a worthwhile investment. Look for one with a high-frequency start for easier arc initiation. For 304 stainless, use ER308L filler rods (1.6mm or 2mm diameter works well) and pure argon as your shielding gas, no need for mixes here.
To avoid warping (stainless loves to distort under heat), tack weld your pieces frequently to hold the shape, use a low amperage (around 50-70 amps for 2mm) and weld in short bursts to make the metal cool between passes. A copper backing bar can also help absorb heat and keep things flat.
Stick Welding Thin Stainless
Your stick welder can work for stainless but it’s tricky on 2mm material. Stick welding generates a lot of heat which can burn through thin stock or cause warping. If you go this route, use E308L-16 electrodes and keep the amperage low (around 40-60 amps). If i says honestly, for brackets and a grill frame, MIG or TIG will give you better control and cleaner results. Reserve stick for thicker stainless or repairs.
Prevent Sugaring and Rust
“Sugaring” (that ugly, black, sugary-looking oxidation on the weld’s backside) happens when there’s not enough shielding gas on the back of the weld. For your grill, use a purge setup with argon gas to protect the back of the weld, especially for TIG. For MIG, a tight fit-up and good gas coverage help. If purging isn’t an option, apply a solar flux paste to the backside before welding, it’s a game-changer.
To prevent weld rust (especially since it’s an outdoor grill), clean the stainless thoroughly before welding. Use a stainless steel wire brush (dedicated to stainless only) and degrease with acetone to remove oils and dirt. Post-weld, passivate the weld with a pickling paste or a nitric acid solution to restore the chromium oxide layer that keeps stainless corrosion-resistant. This will help your welds stay shiny and rust-free.
Welding Stainless to Mild Steel
For joining 304 stainless to mild steel (like parts of your frame), ER309L wire or rods are your best bet. They’re designed for dissimilar metals and provide a strong bond. Make sure to clean both surfaces well, and if you’re MIG welding, stick with the tri-mix gas. Keep the heat input balanced to avoid cracking—stainless and mild steel expand and contract differently.
General Stainless Steel welding Tips
Grind or sand the edges of your 304 stainless to remove any mill scale, and bevel edges slightly for better penetration on butt joints.
Stainless conducts heat poorly, so it traps heat and warps easily. Use skip welding (weld a bit, move to another spot, then come back) to spread out the heat.
Keep your workspace free of mild steel dust to avoid contamination, which can cause rust spots. Use separate tools for stainless.
Stainless welding fumes can be nasty, so use a good respirator and ensure your shop is well-ventilated.
As per your project, welding stainless steel for a custom outdoor grill is a cool challenge and it’s awesome that you are diving into it. Since you got experience with mild steel MIG welding, you are already halfway there but stainless does require some tweaks. For your grill project, MIG with ER308L wire and tri-mix gas should get you strong, decent-looking welds without breaking the bank. If you hooked on stainless work, though TIG is worth learning for that pro-level finish. Keep us posted on how it turns out and share some pics of that grill frame when it’s done! What’s your setup like any specific welder model you’re working with?Replace torch electrode if worn, clean tip with alcohol to boost arc.
Apply 3M anti-fog spray and clean with alcohol, My Speedglas lense stays clear.
Wire feed issues is from bad tension. Check drive roll alignment, adjust tension to 3-4 to stabilize feed.
Arc failure comes from bad contact or grounding issues, Check tip for wear or damage, My PowerMIG 260 failed to ignite too, Clean tip with alcohol to remove residue, Set wire speed to 230 ipm for consistency, Use 20 CFH argon for coverage, Set voltage to 22V for stability, Tighten all connections secure, Ensure clean ground clamp, Check for steel contamination.
Use a new pedal cable, It is more reliable.
Replace contact tip on your Miller 141, worn tips jam mig wire, use 220 ipm.
Rough cuts mean wrong settings. Use 40 amps for 1/4-inch steel. My cuts smoothed out. Check torch height at 0.06 inches. Use a guide rail. Slow speed to 20 IPM. Calibrate Hypertherm.
Use a gas lense, it gives better gas coverage for cleaner welds.
Jams comes from bad liner or tension, Clean liner with alcohol thorough, My Esab Rebel jammed too, Adjust drive roll tension proper, Use 230 ipm wire speed, Check for wire kinks, Set voltage to 20V, Replace worn rollers, Ensure proper spool tension.
