12v welder off alternator

Post by guzzla »

have heard of a replacement alternator that has some fat ass cables off it that are used for welding. instead of running off your batteries it runs off your alternator and the amperage output is regulated by engine rpm.

anyone seen it in action or have a link cos im keen as for a look c.

cheers,

alternator welder

Post by davejb »

I have a modified Bosch alternator 80 amp. It does the normal battery charging duties as well as being a welder. No need for a stand alone welder. The windings are changed from star to delta or vice versa, you replace the internal regulator with a brush box and run an external regulator. To weld simply disconnect the main power lead from the battery and connect your welding lead to this, earth to chassis and weld away. Apparently the latest altenators are not suitable for this mod.

If only someone would design an alternator that has normal alternator capabilities, plus welding capability, and a small built-in air compressor... that's a little dream of mine.

Someone has. A 240v Generator/Welder/Compressor/Battery Charger all in one unit.

Problem is, you may not be able to fit it under your bonnet.
