OTC DAIHEN CME-6401 Dedicated Aluminum Wire Feeder System
The OTC DAIHEN CME-6401 is a specialized wire feeder engineered exclusively for feeding soft aluminum and aluminum alloy welding wires. Custom-matched for OTC’s flagship EP400 and EP500 AC/DC pulsed MIG welding machines, it addresses the fundamental challenge of aluminum welding: wire column strength. Utilizing a precision 4-roll drive system with specialized U-groove rollers and ultra-low-friction internal conduits, the CME-6401 eliminates wire flattening, shaving, and micro-arcing, guaranteeing consistent droplet detachment and defect-free aluminum welds.

🔧 Engineering & Operational Guide
- U-Groove Drive Rollers: Always ensure dedicated U-groove aluminum drive rollers are installed. Using V-groove steel rollers will crush soft aluminum wire into an oval shape, causing immediate liner blockage.
- Tension Arm Pressure: Set the drive roll pressure arm to the minimum tension required to feed the wire without slipping. Overtightening will deform the aluminum wire surface.
- Teflon / Graphite Liners: Pair this wire feeder exclusively with Teflon or carbon-graphite torch liners to minimize feed friction over extended torch cable lengths.
