MIG-500 Industrial MIG Welder 500A 4-in-1 Dual IGBT Module | Doughty

MIG-500 — Industrial-Grade Power for the Most Demanding Welding Jobs

When the job calls for welding 50mm steel plate in a shipyard, a steel construction site, or a high-output fabrication shop, you need a machine that won't flinch. The MIG-500 Industrial MIG Welder from Doughty is built for exactly that — dual IGBT modules, 500A output, and a 4-in-1 process capability that handles whatever you throw at it.

Why the MIG-500 is the Industrial Standard:

• Dual IGBT Module Design — 40% enhanced arc stability with 30% reduced energy consumption vs. single-module machines
• 4-in-1 Multi-Process — Gas MIG/MAG, Gasless Flux-Core MIG, and Stick (MMA) welding in one unit
• 500A Maximum Output — Penetrates up to 50mm steel; handles the heaviest structural and industrial work
• 60% Duty Cycle @ 500A / 100% @ 387A — Built for continuous, high-volume production welding
• Independent 20kg Wire Feeder — Detachable, ergonomic feeder with 4-roller dual-drive for fatigue-free operation on large jobs
• Wide Wire Compatibility — Accepts 1.0–1.6mm wire: ER70S solid wire, E71TGS flux core, ER308L stainless steel wire
• 2T/4T Trigger Mode — Switch between modes to match your welding style and reduce operator fatigue
• Gas Check Function — Instantly verify gas flow and torch operation before starting

Ideal Applications:

Shipyards, steel construction, heavy fabrication shops, automotive manufacturing, and any industrial environment where high-amperage, continuous-duty welding is required.
