TIG-250DP — Precision Pulse TIG Welding with 3-in-1 Versatility
When precision matters — on thin stainless steel, dissimilar metals, or critical joints — the TIG-250DP 250A Pulse DC TIG Welder from Doughty gives you the control you need. Advanced IGBT inverter technology, adjustable pulse frequency from 0.5Hz to 100Hz, and a pedal remote for real-time current adjustment make this the go-to machine for professional TIG welders who demand consistent, clean results.
Why the TIG-250DP Delivers Professional Results:
- 3-in-1 Multi-Process — DC TIG, Pulse TIG, and Stick (MMA) welding in one machine
- Pulse TIG Capability — Adjustable pulse frequency 0.5–100Hz; cleaner, stronger welds on thin materials and dissimilar metals
- HF High-Frequency Start — Effortless arc ignition without touching the workpiece
- Pedal Remote Control — Real-time current adjustment from over 10 meters away for precise heat control
- 250A Output, Welds Up to 8mm — Handles everything from delicate thin-sheet repairs to heavier fabrication
- 60% Duty Cycle @ 250A / 100% @ 194A — Continuous professional welding without overheating
- Advanced IGBT Inverter — Faster response, reduced energy consumption, superior arc stability
- Adjustable Up/Down Slope & Post-Flow — Fine-tune arc start and crater fill for perfect weld quality
Ideal Applications:
Stainless steel fabrication, automotive repair, kitchen equipment, hardware manufacturing, power construction, building fabrication, and any precision welding project where arc control is critical.

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.
