Applications for Diesel Engine Welders

When electrical power is not available, two options are available: weld with a flame or start up a welding generator. Because of weld quality concerns with the former option, a generator is often the way to go. Similar to gas engine welding generators, diesel engine welding generators give welders the power they need to create an electrical arc and fuse metal together. Diesel engine welding generators also supply power to auxiliary equipment, such as wire feeders and grinders. Diesel engine welding generators are intended to supply power under the most extreme conditions. They are frequently used in welding applications that are performed in very cold environments.
