0349311890 - ESAB Caddy Mig Drive Roll .023-.040 Replacement

Precision Drive Roll for ESAB Caddy Mig Inverters

The ESAB 0349311890 Feed Roller is the OEM replacement drive roll for the Caddy Mig C160i and Caddy Mig C200i portable inverter welding power sources. This component is critical for the wire feed system, acting as the primary interface between the motor's torque and the welding consumable. It is machined with precision grooves designed to grip solid MIG wires ranging from 0.6mm (0.023 inches) to 1.0mm (0.040 inches) effectively, minimizing friction while maximizing traction.

For professional welders, feedability is a primary concern. Poor feedability results in micro-arcing at the contact tip, burn-backs, and unstable arc lengths. This roller features a geometry optimized for standard solid wires (mild steel, stainless steel). The surface finish and hardness of the roller are calibrated to prevent the deformation of the wire, which is crucial when feeding softer wires or operating at the higher end of the machine's speed range. The 0.6-1.0mm range covers the vast majority of applications for the Caddy Mig series, making this a standard 'must-have' spare part for your maintenance kit.

Technical Application Notes:
When installing this roller, ensure the pressure arm is adjusted correctly. Over-tightening can deform the wire (creating an oval cross-section) which increases drag in the liner and contact tip. Under-tightening will cause slippage and erratic feeding. This roller is designed to work in conjunction with the Caddy Mig's specific feed motor characteristics. Inspect your current roller for groove wear; if the V-groove has become U-shaped or widened, traction is lost, and replacement is necessary to restore arc stability.
