A selection of videos covering Site welder generators 




DC multi-process diesel engine driven welder designed especially for contractors, maintenance and repair and all other field based welding professionals who demand the best welding arc from an engine driven welder.


Great for off-shore welding, off-site fabrication and when not in use as a diesel welder can be used as a stand alone generator for power.

 It is common to to save fuel and servicing costs to paralell up diesel welders ensuring that only the required power is generated depending on the demand. Did you know you can do that with other welding machines too? 

Lincoln Diesel welderWhen you need it all, consider the rugged Lincoln Air Vantage 500 diesel welder for railroad, mining, heavy duty construction, and rental fleet use. A direct gear-driven compressor, with no belts or clutches to wear out, pumps out plenty of air for arc gouging with up to 3/8" carbons, plasma cutting or almost any air tool.

A powerful 500 amps at 100% duty cycle is enough for almost any stick, TIG, MIG or flux-cored welding project. And, the precision arc starting provided by Chopper Technology and Touch-Start™ DC TIG will make any operator a better welder. Don’t pay extra for plenty of AC generator power - up to 20,000 watts of 3-phase and 12,000 watts of 1-phase is standard.

Stainless steel roof and side panels provide added durability and corrosion-resistance. The reliable Cummins B3.3 water-cooled diesel engine will keep you running — and working — for a long time.

Stick, TIG, MIG, Flux-Cored, Gouging
