Fronius Original CMT Cold Metal Transfer Drive Roll 42,0001,5735
The 42,0001,5735 is an ultra-premium original CMT Drive Roll engineered exclusively for the revolutionary Fronius CMT (Cold Metal Transfer) welding process. Unlike standard wire feeders, CMT technology requires high-frequency mechanical ‘push-pull’ retraction up to 130 times per second. To withstand this immense fatigue stress, this drive roll is milled from ultra-hardened, wear-resistant alloy tool steel with micron-level gear tooth precision. It completely eliminates wire slippage, wire shaving, and erratic arc dynamics, ensuring flawless droplet detachment and spatter-free welds.

🔧 Engineering & Maintenance Guide
- Avoid Over-Tensioning: Never overtighten the pressure arm on the wire feeder. Because CMT pushes and pulls continuously, excessive pressure will crush and deform the wire, turning it into a file that destroys the torch liner and contact tip.
- High-Frequency Slipping: If you hear a ‘screeching’ sound or notice the CMT arc trembling, the drive roll teeth may be worn flat. Once traction is lost, the CMT droplet detachment logic is broken. Replace drive rolls in pairs.
- Metal Dust Buildup: Wire shavings, rust inhibitors, and dust easily pack into the tiny gear teeth, causing slippage. Clean the drive rolls weekly using a wire brush and compressed air.
