Important Options and Specs to Take into account When Selecting a MIG Welder
Energy Output
The ability output of a MIG welder is measured in amps. The next amperage will let you weld thicker metals and produce stronger welds. For many house and pastime use, a welder with an output of 120 to 180 amps is adequate. Nevertheless, should you plan on welding thicker metals or doing intensive welding, chances are you’ll need to select a welder with a better output.
Responsibility Cycle
The obligation cycle of a MIG welder is the period of time it might probably weld constantly earlier than it must relaxation. Responsibility cycles are expressed as a proportion, and a better obligation cycle signifies an extended welding time. For instance, an obligation cycle of 60% signifies that the welder can weld for six minutes out of each 10 minutes. The next obligation cycle is essential should you plan on doing prolonged welding classes.
Wire Feed Pace
The wire feed velocity of a MIG welder is the speed at which the welding wire is fed into the weld pool. A sooner wire feed velocity will produce a wider weld bead, whereas a slower feed velocity will produce a narrower weld bead. The optimum wire feed velocity will rely upon the thickness of the steel being welded and the kind of weld joint. Most MIG welders have a variable wire feed velocity management, which lets you alter the velocity to fit your wants.
