SEE IT IN ACTION -- Fast MIG Real Test
The ARCPEX MIG200 DP LCD is a professional-grade 200A Dual Pulse MIG welder engineered for welders who demand TIG-quality aluminum results at MIG speed. Featuring exclusive Fast MIG, Cold MIG, UP MIG modes, an Industrial Dual Drive 4-Roller wire feed system, Smart PFC power technology, and a full-color LCD display -- this is the most capable MIG welder in the ARCPEX lineup.
DUAL PULSE -- TIG-Quality Aluminum at MIG Speed
Achieve flawless fish-scale beads on aluminum, stainless, and thin steel. 6 dedicated aluminum modes (DC Syn, Pulse, Dual Pulse, Man MIG, CO2 GAS, Gasless). Spool Gun compatible via 12-pin aviation connector (sold separately).
COLD MIG -- The Thin Metal Specialist
Designed to minimize heat input on 0.8mm-1.2mm aluminum and auto body panels. Achieve professional TIG-quality aesthetics with the ease and speed of MIG welding, while helping prevent burn-through on heat-sensitive materials.
UP MIG -- Flawless Vertical Welds
Specialized pulse frequency stabilizes the molten pool during vertical-up welding. Achieve consistent penetration and stacked-dime aesthetics on vertical joints. Perfect for structural repairs and heavy-duty fabrication.
FAST MIG -- Maximum Shop Efficiency
Optimized arc energy for rapid wire melting and higher deposition rates. Designed for long beads and high-volume fabrication. Full 200A output on 220V for heavy aluminum and steel -- or run on 110V household power for light work.
4-ROLLER DUAL-DRIVE -- No More Wire Jams
Our heavy-duty 4-Roller Dual-Drive system grips soft aluminum wire from four sides to promote smooth, consistent delivery through standard torches. This enhanced stability allows you to weld aluminum reliably without the constant struggle of wire jams, reducing the immediate need for expensive spool guns.
PRO-SMART LCD -- 6 Languages & 10-Job Memory
High-contrast LCD screen provides clear data visibility even with your welding helmet down. Supports 6 major languages (English, Spanish, German, French, Polish, and Portuguese). 10-Group Job Memory recalls your settings in seconds.
100% PURE COPPER CABLES -- Not Aluminum-Core
10FT ground clamp and electrode holder with solid pure copper cores -- maximum conductivity, heat resistance, and longevity. Most competitors use aluminum-core cables that degrade faster and run hotter. These durable cables withstand repeated dragging and bending without cracking or failing.
INDUSTRIAL DUAL-FAN COOLING -- Built to Run All Day
Two independent smart fans create a high-pressure airpath across the entire motherboard. Smart Sleeping Mode activates fans only when needed -- keeping metallic dust out and maintaining a 60% duty cycle @ 200A for an extended component service life.
SMART PFC -- No Tripped Breakers. No Flickering Lights.
Advanced PFC (Power Factor Correction) promotes stable, efficient operation on both 110V and 220V. Designed for rock-solid arc performance even on unstable power grids or long extension cords -- suitable for home shops and remote job sites.
