Tweco 2-1-MPC Male Cable Connector, Size 2 (1/0 - 3/0 AWG)

Reliable Connections for Serious Welders

When you're dragging cable across the shop floor or up scaffolding, the last thing you need is a connector that pops apart or overheats. The Tweco 2-1-MPC Male Cable Connector (9425-1247) is the industry standard for a reason—it stays connected and keeps the power flowing. Designed to fit 1/0, 2/0, and 3/0 AWG cables, this Size 2 connector is the perfect choice for building extension leads or replacing worn-out ends on your stinger whip.

Why Welders Trust Tweco MPC:

• Solid Lock: The cam-action design means once you twist it, it stays locked. No more taping connectors together to keep them from pulling apart mid-weld.
• Cooler Running: The ball-point screw connection digs in tight (without cutting strands) for excellent conductivity. Less resistance means less heat at the joint and more power at the arc.
• Tough Build: The heavy-duty cover can take a beating. Drop it, drag it, or step on it—it’s built to survive the daily grind of a welding shop.

Installation is quick and easy with a simple hex key. Just strip your cable, insert it into the brass body, tighten the ball-point screw, and slide the cover on. This male connector pairs with any Size 2 female Tweco-style connector, giving you the flexibility to extend your reach whenever the job demands it. Don't settle for cheap knock-offs that arc and melt; stick with the original Tweco MPC for a connection you can count on.
