WeldingMart has been an authorized Lincoln Electric dealer since 2003, shipping genuine factory-certified welding equipment from our warehouse in Wisconsin to professionals and fabricators across the United States. Our staff includes certified welding professionals who can assist with process selection, consumable compatibility, and application-specific parameter recommendations — call or chat before you buy to ensure you're ordering the right machine for your application.
This machine supports MIG (GMAW), Flux-Cored (FCAW). All listed processes are selectable from the front panel. Refer to the Owner's Manual for recommended parameters for each process.
The machine operates on 208V, 230V, 460V, multi-voltage input power. It includes automatic voltage detection — no switch or re-link required. Consult a licensed electrician for proper circuit and disconnect sizing.
This welder operates on single-phase power. Single-phase machines connect to standard commercial or industrial single-phase service.
Duty cycle is the percentage of a 10-minute period the welder can operate at its rated amperage without overheating. This machine is rated 40% @ 250A. Exceeding the duty cycle triggers thermal protection; allow the unit to cool before resuming welding.
This machine is compatible with wire diameters of 0.025", 3/64". Solid and flux-cored wire are both supported with appropriate drive roll changes. Refer to the drive roll specification chart in the Owner's Manual.
Rated for welding material from 24 ga, 22-18 ga, 1/8", 3/16", 1/4". Thicker sections may require multiple passes or preheat depending on base metal and joint design. Refer to Lincoln Electric's recommended parameter charts for specific amperage and wire speed settings.
The package includes the welding machine, MIG gun, work clamp and cable, drive rolls, and operator's manual. Specific kit contents are listed in the What's in the Box section above. Shielding gas cylinder and wire spool are not included — sold separately.
