⚡️ 300A RAW POWER, UNSTOPPABLE PERFORMANCE
Meet the MMA-350 Stick Welding Machine—engineered to dominate the toughest jobs. With a monster 300A output and 60% duty cycle at 40°C, this beast delivers non-stop welding even under extreme conditions. Weld steel, stainless, alloy plates, or low-hydrogen 7018 rods like a pro, with electrode compatibility up to 6.0mm thick rods for deep-penetration magic. No more downtime—just pure, relentless power.
🛡️ ADVANCED IGBT TECH: SMARTER, SAFER, STRONGER
Powered by dual IGBT modules and military-grade circuitry, the MMA-350 Stick Welding Machine transforms unstable grids into rock-solid DC arcs. While auto-shield against overheat/overload keeps you safe in shipyards, pipelines, or confined tanks. Plus, Hot Start & Anti-Stick functions ignite arcs instantly and prevent rod jams—every single time.
🌍 UNIVERSAL VOLTAGE WARRIOR: PLUG IN ANYWHERE, WELD EVERYTHING
No site is off-limits! The MMA-350 Stick Welding Machine conquers 3-phase 380V inputs ±15% fluctuation tolerance—perfect for generators or sketchy job-site grids. Its 12.2KVA max load capacity feeds hungry electrodes without flinching.
🚀 PORTABLE INDUSTRIAL HERCULES: LIGHTWEIGHT, HEAVY-DUTY
At just 15.0 kg, this compact titan fits in your truck bed yet out-welds clunky dinosaurs. IP21S-rated toughness laughs off dust, sparks, and downpours. Need 100m cable runs? Its 65V open-circuit voltage pushes current farther without sag. Ideal for mobile repair crews, offshore rigs, or farm fixes.
Features：
-Industrial grade dual IGBT module adopted
-High quality: Industrial grade design, with impulse current suppression technology, bias correction technology, anti-single tube thermal shock technology, make the welding machine more steady and reliable.

Vinova Testimonials
I've used all types, brands, mig, tig, spool guns, arc, and for the money this little guy surprised me, outperformed my expectations, hopefully it lasts, welded for 2 hours straight today right out the box. Only downfall is the fixed whip and lack of ability to run gas. But for a portable 110 mig on a 100 ft extension cord it delivered
Jetsk Jon
This mig welder works great for what it is. It's a light duty welder, and they make no claims for it being anything else, but it's absolutely perfect for most home and hobbyist use.
Jesse C. Benton
I ran weld’s within its duty cycle and it performed perfectly. I’m truly impressed by the little button that adjusts the wire feed automatically. As far as performance, weak. If’n it can put out 80 amps I’d be impressed and if cranked up? Well it just kicks off. Maybe my units defective, idk. Nice even arc below 3/4 power though.
