How often are you cutting or gouging?
Many repair jobs in the field require cutting out damaged metal or an old weld. An engine drive gives you the option of using a plasma cutter or carbon arc gouging for this work.
Plasma cutters offer lightweight portability and can cut steel with 10,000 watts of power from an engine drive. Carbon arc gouging is available on most engine drives; machines that offer at least 300 amps of power at a high-duty cycle work best for gouging. If you need to remove a lot of metal, look for an engine drive with a peak output of at least 500 amps. This lets you run 3/8-inch diameter carbons, so you’ll get the job done faster.
Often, work on jobsites also requires the use of different air tools, making compressed air an important function of your engine-driven welder. Miller offers engine-driven welders with built-in air compressors; these machines are denoted with the Air Pak™ label in the name. Be sure to choose a machine that provides the necessary cubic feet per minute (cfm) and pressure required for the tools you will run most often.
