Types of Engine Driven Welders

Engine driven welders are used where there is a lack of electric power for arc welding, and are designed for outdoor applications. However, they can be used indoors to supply necessary power to electric arc welders. The nature of application, type of engine, portability and AC generator power are some of the factors to consider when choosing an engine-driven welder.

A choice of gas powered engines

There are different types of engine driven welders that include gasoline, diesel, and LPG or liquid propane gas. Gasoline engines are ideal in colder climates since they do start easily and do not need ether start kits or other starting aids. Diesel engine driven welders are most popular since they offer a better fuel economy when compared with gasoline engines. They are widely used in refineries since they do not ignite as easily as gasoline. LPG has become an alternative choice especially in indoor applications where exhaust emissions from diesel and gasoline are not permitted.

Choosing the right wattage

When selecting an engine driven welder, it is prudent to consider the need for portability. Smaller gasoline stick welders are easier to be carried or lifted to a work area.  Engine drives come with power generation capabilities from 5000 to 27000 W. Choosing one depends on the tools used and the need to simultaneously weld. Different tools require different wattage. Grinders require 1800 W, air compressors a minimum of 8200 W, plasma arc cutters up to 12000 W. Considering these factors will help choose the right unit.
