The new Transmig™ 500HD gives you access to serious welding power across MIG, STICK, TIG DC-Lift, and powerful Arc Gouging, all backed by an 80% duty cycle at 500A for those long, uninterrupted weld runs in high-demand industrial environments.

To take it a step further, the Transmig 500HD seamlessly connects with the Transfeed 4R HD Wirefeeder (included in the plant package), offering a 4 Roll Geared Wire Drive system that handles 200mm and 300mm wire spools with absolute precision.

Need it mobile? No worries — with 10m interconnection leads, built-in 2-point lifting lugs, and a robust HD trolley, the Transmig 500HD is ready to move wherever the work takes you.

HEAVY DUTY. BRUTE POWER. ZERO HASSLE 

The Transmig 500HD has gouging capabilities with up to 9.5mm carbon rods, giving you the flexibility to prep and repair on the fly. Its arc stability and control are just as sharp with Hot Start, Arc Force, Adjustable Burnback and Crater Fill on MIG, giving you fine-tuned arc response across any process.

It is your ultimate solution for heavy fabrication, workshop production, mining, structural welding and repair work. Air or water cooled, it won’t miss a beat.

With an 80% duty cycle at 500A, you’ll get extended performance under pressure, and thanks to the built-in Voltage Reduction Device (VRD) , you can switch back to STICK welding with added operator safety. Run it with the included Tweco TW4 HD MIG Gun for precision work and added versatility.
