Alternator Powered On-Vehicle Welder

Pre-Modified, Dual Rectifier CS144 for Use as an On-Vehicle Welder

Alternators with the best possible components available in the industry. Everything about our CS144 alternator is quality. From heavier castings to industry leading NTN and INA bearings. Even our internal regulators (optional) use durable components and a board-free welded design. The dual and quad wound stator designs also ensure you get plenty of welding power without having to rev the engine.

Easy To Use, One Alternator for Charging and Welding

We selected our Extreme Duty Dual Rectifier as the best possible power source for an onboard welder. Unlike other onboard welding alternators, our CS144 can replace your current unit. No need to purchase or fabricate a complicated bracket. The CS144 is drop in compatible with hundreds of vehicles, and can be adapted into hundreds more with simple, prefabricated bracket systems.

The Difference is in The Diodes

A lot of alternators use cheaper avalanche diodes in their bridge rectifier. If you try to use these alternators in an onboard welder, they will short out and fail. Our alternator uses dual non-avalanche rectifiers rated to 210A a piece. Spreading the current over two sets of diodes means less heat in the case and longer alternator life.
