What welding processes does the Lincoln POWER MIG® 260 MIG Welder support?

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.

What input voltage is required?

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.

Is this a single-phase or three-phase machine?

This welder operates on single-phase power. Single-phase machines connect to standard commercial or industrial single-phase service.

What does duty cycle mean, and what is this machine's duty cycle?

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.

What wire diameters are compatible?

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.

What material thicknesses can this welder handle?

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.

What is included with the purchase?

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.

Is this machine covered by a manufacturer warranty?

Yes. Lincoln Electric welders purchased through WeldingMart as an authorized distributor are covered by the manufacturer's standard warranty. Warranty terms vary by model — refer to the documentation included with the unit or contact WeldingMart for warranty details specific to this product.

What is WeldingMart's return policy?
