Important Options and Specs to Think about When Selecting a MIG Welder
Energy Output
The ability output of a MIG welder is measured in amps. A better amperage will assist you to weld thicker metals and produce stronger welds. For many dwelling and interest use, a welder with an output of 120 to 180 amps is enough. Nevertheless, in case you plan on welding thicker metals or doing intensive welding, you could wish to select a welder with the next output.
Responsibility Cycle
The obligation cycle of a MIG welder is the period of time it may well weld repeatedly earlier than it must relaxation. Responsibility cycles are expressed as a share, and the next obligation cycle signifies an extended welding time. For instance, an obligation cycle of 60% implies that the welder can weld for six minutes out of each 10 minutes. A better obligation cycle is essential in case 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 quicker 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 on 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 modify the velocity to fit your wants.
