MMA-315 — 100% Duty Cycle Stick Welder for Non-Stop Industrial Welding
When the job demands continuous welding without interruption, the MMA-315 Digital IGBT Stick Welder from Doughty is the machine you reach for. 100% duty cycle at 260A, auto-switching dual voltage, and a compact 9.2kg body that goes wherever the work takes you.
Why the MMA-315 Stands Out:
- 100% Duty Cycle @ 260A — Run 4.0mm electrodes 24 hours straight without stopping; ideal for pipeline, structural steel, and farm equipment
- Auto Dual Voltage 220V/380V — Automatically detects and adapts to workshop or industrial power; no manual switching needed
- Hot Start — Instant arc ignition on 6010/6011 cellulose rods with zero sticking
- Adjustable Arc Force — Fine-tune penetration for 6013 (soft) or 7018 (aggressive) rods
- 5.0mm Electrode Capacity — Deep fusion on carbon steel, stainless, cast iron, and more
- Digital Display — Rotate to set current; auto-suggests optimal electrode diameter
- IGBT Inverter Technology — Anti-thermal shock design for rock-solid reliability in marathon sessions
- Full Safety Protection — Overload, overheat, overcurrent protection; IP21S rated
- Ultra-Portable at 9.2kg — Lighter than a car battery; fits in tight spaces and remote job sites

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

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.
