Important Options and Specs to Contemplate When Selecting a MIG Welder
Energy Output
The ability output of a MIG welder is measured in amps. The next amperage will help you weld thicker metals and produce stronger welds. For many house and passion use, a welder with an output of 120 to 180 amps is enough. Nonetheless, in case you plan on welding thicker metals or doing intensive welding, chances are you’ll need to select a welder with the next output.
Responsibility Cycle
The obligation cycle of a MIG welder is the period of time it could actually weld constantly 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% signifies that the welder can weld for six minutes out of each 10 minutes. The next obligation cycle is necessary in case you plan on doing prolonged welding periods.
Wire Feed Pace
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 depend upon 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 regulate the pace to fit your wants.
