The Forney® 160 STx is a dual-voltage stick and DC TIG welder that pairs serious 160 amp performance with a next-generation, large bright display and simple one-knob control. Run it on 120V household power for lighter jobs, or step up to 240V to weld thicker material up to 3/8 in. in a single pass, with adjustable arc force and 6010‑capable output that lets you tackle demanding open‑root work. Backed by a 3-year warranty and Forney® Industries’ 90+ years of welding experience, this dual-voltage stick and TIG welder is built for contractors, farmers, and serious DIYers who need a portable machine that still feels like a pro-grade stick welder.
  • Expert-Tech® support gives you a direct line to Forney’s technical team for setup, troubleshooting, and parts; all from real welders based in Colorado, USA
  • 3-year warranty delivers long-term assurance so you can rely on the 160 STx for ongoing repair, maintenance, and fabrication work
  • Bright passive LCD with large readout delivers a next-generation panel that makes it easy to see your amperage and settings in dim shops or bright outdoor light
  • 6010-capable stick output delivers the digging arc and high open-circuit voltage needed to run E6010 electrodes for open-root passes and work on dirty or rusty materials
  • Adjustable arc force control delivers the ability to fine-tune the arc to match different rods and techniques
  • Dual input voltage (120V / 240V) delivers flexibility so you can plug into household power for small jobs or step up to 240V in the shop or field for full 160 amp output
  • Compact, lightweight inverter with handle and carry strap delivers portability so you can carry the welder, wrap the leads, and bring it directly to the work
  • Lift start TIG capability (DC TIG) delivers more precise heat control on thin metal so you can produce cleaner, more controlled weld beads when appearance matters
  • Generator-capable design delivers remote welding capability so you can run from a 4,000 W (120V) or 10,000 W (240V) generator with no low-idle
  • CSA certified to meet strict safety and performance standards ensuring reliability and your safety in any work environment
  • One-knob interface with Expert-Set Hot Start delivers easy amperage control and reliable arc starts
