OEM power / load resistor removed from a working Lincoln Wire-Matic 255 MIG welder.

This is a large ceramic-coated wirewound resistor used in the DC power section to safely bleed off residual voltage from the capacitor bank, assist with startup load balancing, and protect internal components during power-down.

Condition:

• Pulled from a working machine

• No visible cracks, burns, or ceramic damage

• Heavy-duty mounting lugs are intact and solid

• Normal cosmetic wear from industrial service

• Not modified or repaired

Function / Application:

• Capacitor discharge (bleeder resistor)

• Load stabilization during startup/shutdown

• Protects rectifier and control circuitry from voltage spikes

Construction Details:

• Long cylindrical ceramic-coated body

• Wirewound internal element

• Heavy-duty terminal lugs for high-current use

• Designed for continuous industrial duty

What’s Included:

• Power resistor exactly as shown in photos

• Mounting lugs attached

• No additional hardware or wiring included

Notes:

• Used OEM electrical component

• Buyer should confirm resistance value and compatibility with their specific Wire-Matic 255 revision

• Intended for professional installation

Hard-to-find OEM part for maintaining proper DC behavior in older Lincoln industrial MIG welders.
