Brass Power Cable Adapter

This brass power cable adapter connects compatible TIG torches to a power source. It fits Miller Weldcraft WP-9 and WP-17 series torches including multiple sub-models. The adapter suits professional welders and fabrication shops needing a reliable replacement connection.

Replaces Worn Threaded Adapters

The adapter upgrades a damaged or corroded threaded connection on existing torch cables. It restores secure electrical contact when the original fitting strips or loosens. The jump is worth it when intermittent arcs or overheating appear at the torch-to-cable joint.

Threaded 3/8-24 to 5/8-18RH Interface

The adapter uses a 3/8 inch -24 thread on one end and a 5/8 inch -18RH thread on the other. This specific thread pairing limits use to torches designed for that exact combination. It cannot connect to torches or power sources with different thread pitches or diameters.

Questions about this item

What thread sizes does the brass power cable adapter need to connect to the torch and power source?

The adapter has a 3/8 In.-24 threaded connection on one end and a 5/8 In.-18RH threaded connection on the other.

How do I install the adapter onto a WP-9 or WP-17 series torch, and what step is often missed?

Thread the 3/8 In.-24 end into the torch power cable and the 5/8 In.-18RH end into the power source; the step often missed is tightening both connections firmly to prevent arcing.

When should the brass power cable adapter be replaced during routine maintenance?

Replace the adapter if the brass threads show wear, corrosion, or if the connection becomes loose, as this affects current flow to the torch.
