Forney® 125 FCx

The Forney® 125 FCx is a 120V TruSet™ flux core welder that makes dialing in the right settings as easy as turning a knob and striking an arc. TruSet™ presets, a bright passive LCD display, and simple two-knob controls help you get welding quickly, while the 125 amp inverter output handles 24 ga through 3/16 in mild steel in a single pass. Backed by a 3-year warranty and Forney® Industries’ 90+ years of welding experience, this TruSet flux core welder is built for DIYers who want a portable, gasless machine that is still easy to grow with.

Key features & benefits:

• TruSet™ flux core presets deliver fast setup with ideal voltage and wire feed combinations so you can get a usable arc quickly instead of guessing at settings.
• Expert tech and American support delivers confidence so you can call Forney’s U.S.-based service team for help with setup, troubleshooting, and parts when you need it.
• 3-year warranty delivers long-term assurance so you can invest in a machine that is designed to stay in your lineup for years of projects.
• Bright passive LCD display with large readout delivers next-generation panel visibility so you can clearly see settings in dim garages or bright daylight.
• 120V input power delivers plug-and-play operation so you can weld anywhere you have a standard household outlet or compatible generator.
• Gasless flux core welder (FCAW) delivers welds without shielding gas so you can work outdoors or on the farm with fewer setup steps and no bottles to haul.
• Compact inverter design with integrated 8 ft torch and ground delivers a small, portable package so you can carry the welder and wrap the leads directly on the built-in handle between welds.
• 125 amp output with 30% duty cycle at 90 A delivers enough power and arc time so you can weld from 24 ga sheet up to 3/16 in mild steel in a single pass on typical home and repair projects.
• Generator-capable (4,000 W minimum) delivers flexibility so you can weld where there is no permanent power using a properly sized 4,000 W generator with no low-idle and 5% THD max.
• Tweco®-style consumables with toolless 1/4-turn despooler deliver easy access to industry-standard tips and nozzles and quick wire changes so you can spend more time welding and less time re-threading.

In real-world use, the Forney® 125 FCx plugs into a standard 120V outlet yet still delivers up to 125 amps of output—enough to weld common mild steel from thin 24 ga up to 3/16 in plate for brackets, frames, and repairs. The 30% duty cycle at 90 amps gives you several minutes of weld time in each 10-minute cycle before the machine needs to cool, which aligns well with typical DIY stitch-weld and short-bead workflows. TruSet™ presets and the bright display reduce guesswork, helping newer welders get workable settings faster while still allowing manual fine-tuning as skills progress. The compact inverter, integrated 8 ft leads, handle, and carry strap make it easy to grab the machine, wrap the cables, and move anywhere you have power or a compatible generator.

Ideal for:

• Home and garage projects like building carts, benches, brackets, and small frames from 24 ga–3/16 in mild steel.
• Farm and property repairs on gates, small implements, and equipment where a portable 120V flux core welder for farm repairs is more convenient than moving material.
• Maintenance and repair work in driveways, sheds, and outbuildings where gas bottles and 240V power are not practical.
• New welders who want TruSet™-guided setup and a bright display to shorten the learning curve on flux core welding.
