OVERVIEW

Restore Your Welder's Performance

Is your trusted Transmig 140 or 180 starting to act up? There is nothing more frustrating than laying down a bead only to have the wire sputter, stop, or feed unevenly. Often, these issues aren't caused by your technique, but by a tired or failing wire feed motor. The Motor + Gearbox Assembly (W7004002) is the specific cure for these ailments, designed to get your machine running like the day you bought it.

The wire feed mechanism is the heart of your MIG welder. When the motor gets weak or the gears inside the box start to slip, you lose the consistent wire delivery needed for a smooth, stable arc. This leads to burn-back (where the wire fuses to the tip), bird-nesting at the drive rolls, and ugly, inconsistent welds. Instead of struggling with constant adjustments or considering buying a whole new machine, you can simply swap out the drive assembly.

Why choose this replacement?

  • Perfect Fit: This isn't a generic "one-size-fits-all" motor. It is designed specifically for the Transmig F140 and F180 models, meaning the bolt holes line up and the shaft fits your existing drive rolls.
  • Smooth Operation: The fresh gearbox ensures steady torque, pushing the wire through the torch cable even if it's twisted around the shop floor.
  • Easy Repair: In most cases, replacing the motor is a straightforward job that can be done with basic hand tools in your own garage or workshop.

Don't let a bad motor stall your projects. Whether you are working on automotive bodywork, light fabrication, or general repairs, reliable wire feeding is non-negotiable. Install the W7004002 Motor + Gearbox and get back to welding with confidence.

FAQ

This motor and gearbox assembly is designed specifically for the Cigweld Transmig 140 and Transmig 180 series welders (often denoted as F140/180).

No, this item is the Motor + Gearbox assembly only. You will typically transfer your existing drive rolls to the new shaft or purchase them separately.

Symptoms include erratic wire speed that doesn't change when you adjust the dial, the motor making grinding noises, or the wire stopping completely while the trigger is pulled and the relay clicks.

The voltage specification matches the OEM design for the Transmig 140/180 control boards. Please consult your machine's schematic, but it is a direct replacement for the stock part W7004002.

Yes, replacing the wire feed motor is generally a straightforward repair involving removing the machine cover, unbolting the old assembly, and disconnecting the wires. Always unplug the machine from power before servicing.

The motor and gearbox are integrated into a single unit to ensure the correct gear reduction ratio and torque output required for pushing welding wire. They are replaced as a set.

If the slipping is caused by a weak motor or stripped internal gears, yes. However, also check that your liner is clean, the contact tip is good, and the drive roll tension is set correctly.

This is a replacement part designed to meet or exceed the specifications of the original manufacturer part number W7004002.
