Miller Multimatic 255 MIG TIG Stick Welder – 20-350A Amp Range, P/N 951767

Depositing spatter-free pulsed MIG and precision TIG beads, the Miller Multimatic 255 MIG TIG Stick welder (P/N 951767) delivers a complete 350-amp multi-process workshop station with EZ-Latch running gear. Fabrication facilities lose billable days purchasing separate TIG torches, remote foot controls, MIG guns, and running carts to assemble complete multi-metal cells. This complete package bundles the 350-amp powerhead with an EZ-Latch running cart, an MDX-250 MIG gun, a high-flex TIG torch, an industrial foot pedal remote, and dual gas regulators.

Dual gas connections allow operators to keep pure argon for TIG and mixed gas for MIG plumbed to the machine simultaneously, eliminating gas bottle changeover delays. Auto-Set Elite technology configures optimal arc voltage and wire feed speed across various material thicknesses, while pulsed MIG programs deposit flat weld beads on vertical-up joints without puddle sagging. The tool-free EZ-Latch cart unlatches in seconds, allowing crews to lift the 84-pound power source into truck beds for remote field service.

Key Engineering Features of Miller Multimatic 255 (P/N 951767)

- Complete TIG and MIG Multi-Process System: Bundles Multimatic 255, EZ-Latch cart, foot pedal, TIG torch, and MDX-250 gun.
- 20-350A Commercial Output Window: Handles light gauge sheet metal up to 1/2-inch structural plate in a single pass.
- Dual Gas Flowmeter Connections: Connects argon and mixed shielding gas bottles simultaneously, eliminating bottle changeover downtime.
- Foot Pedal Remote Amperage Control: Delivers stepless heat adjustment to control puddle freeze and prevent crater cracking.
- Tool-Free EZ-Latch Running Gear: Latches and unlatches the powerhead from the cart base in seconds for mobile field transport.
- Integrated Pulsed MIG Technology: Produces clean, spatter-free weld beads on carbon steel, stainless, and aluminum.

Shop Floor Durability & Deposition Rates

Built for structural manufacturing and pipe fabrication, this complete multi-process station delivers maximum metal deposition with low cleanup labor.

- Complete system integration eliminates equipment sourcing delays, allowing production lines to start welding on arrival.
- Foot pedal remote control lets you adjust heat dynamically while welding out-of-position roll cage joints and exhaust collectors.
- Pulsed MIG waveforms produce flat weld beads with zero spatter, slashing post-weld grinding and chipping hammer hours.

Plate Thickness Clearance & Field Portability

Weighing 84 pounds dry with a cart base length of 40 inches, this multi-process workstation fuses 1/2-inch steel plate in a single pass and rolls between fabrication bays on heavy rubber tires.

Warranty Coverage & Field Maintenance

- Miller Electric backs the Multimatic 255 powerhead and EZ-Latch cart with a 3-Year True Blue warranty.
- The MDX-250 MIG gun, TIG torch, and foot remote assembly receive 1-Year manufacturer warranty protection.

Clean drive roll grooves weekly with a wire brush, blow dry compressed air through the gun liner during wire spool changes, and inspect copper contact tips daily for keyhole erosion.
