Thorworx MIG-200 4-in-1 Multi-Process Inverter Welder (Dual-Voltage 120/240V)

The THORWORX MIG-200 is a professional-grade 4-in-1 multi-process welder engineered for power, precision, and all-day durability. Built around Fairchild IGBTs from ON Semiconductor and paired with dual 105°C industrial capacitors, the MIG-200 delivers a stable, consistent arc at full rated output across gas MIG on structural steel, flux-core wire, stick on heavy plate, and lift TIG on thinner material. Dual-Voltage (110V/220V) input means it works in your garage or on a job site, with no compromises.

The ThorSync™ Synergic Control system automatically matches voltage to wire speed. Set your wire feed rate and the machine does the rest. From heavy steel to delicate stainless, the THORWORX MIG-200 is "Forged for Power, Built to Last."

Key Features and Benefits

• 4-in-1 Multi-Process Capability: Supports Gas MIG (GMAW), Flux Core (FCAW), Stick (MMA), and Lift TIG welding in a single machine. Welds steel and stainless steel out of the box; aluminum-ready with an optional spool gun (sold separately).
• ThorSync™ Synergic Control: Set your wire speed and the machine automatically matches voltage for clean, dialed-in welds with no trial-and-error.
• Dual-Voltage Input: Operates on both 110V and 220V (50/60 Hz) for maximum portability. Recommended 35A breaker on 110V, 25A on 220V.
• Steps Mode (2T/4T Toggle): 2T mode (hold trigger to weld, release to stop) for short tacks and precision work; 4T mode (press once to lock the arc on) for long, uninterrupted runs.
• Adjustable Gas Flow: Pre-flow purges air from the torch before the arc strikes; post-flow shields the weld pool as it cools. Both are independently adjustable for cleaner results.
• Pulse Mode: Reduces heat input to weld thin sheet metal without burnthrough or warping, giving you fine control over heat-sensitive materials.
• Upgraded Internals: Fairchild IGBTs from ON Semiconductor, dual 105°C capacitors, and oversized aluminum heat sinks engineered for sustained heavy-duty shop use. Built-in protections cover over-current, over-voltage, over-load, and overheating, with automatic voltage fluctuation compensation and VRD for added operator safety.
• Heavy Gauge. Heavy Duty: 35mm² full copper welding cables minimize resistance and maximize current delivery. 24KD MIG torch with Teflon liner rated above the machine's full output. 400A copper-and-brass ground clamp with grooved jaw. 300A copper electrode holder. Accepts both 1 kg (4-inch) and 5 kg (8-inch) wire spools.
• cETL Listed: Certified to Canadian electrical safety standards per IEC 60974-1, with a rated 60% duty cycle at 200A.
• Canadian Brand. Canadian Support: Thorworx Industries is based in Niagara Falls, Ontario. We specified every component inside this machine and stand behind it with a 2-year warranty and 3 years of after-sale support from your purchase date. Real people, based in Canada, who answer the phone and respond within 24 hours.
