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 permit you to weld thicker metals and produce stronger welds. For many residence and interest use, a welder with an output of 120 to 180 amps is ample. Nonetheless, for those who plan on welding thicker metals or doing intensive welding, you could wish to select a welder with a better output.
Obligation Cycle
The obligation cycle of a MIG welder is the period of time it could possibly weld constantly earlier than it must relaxation. Obligation cycles are expressed as a share, and a better 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. The next obligation cycle is necessary for those who plan on doing prolonged welding periods.
Wire Feed Velocity
The wire feed pace of a MIG welder is the speed at which the welding wire is fed into the weld pool. A quicker wire feed pace will produce a wider weld bead, whereas a slower feed pace will produce a narrower weld bead. The optimum wire feed pace will rely on the thickness of the metallic being welded and the kind of weld joint. Most MIG welders have a variable wire feed pace management, which lets you alter the pace to fit your wants.
