Amp Welding Output Range
While the Pro-MIG 140 and the Handler 140 share the same peak amp welding output, the minimum number for the Lincoln machine is 30 amps, while that of the Hobart machine is 25 amps. Thus the Handler 140 has a wider range.
The Pro-MIG 140 can weld up to 5/16-inch steel using its self-shielded Lincoln Innershield wire. This surpasses its Hobart counterpart, which, comparatively speaking, can only manage up to 4/16 inch (1/4 inch).
Physical Dimensions and Weight
The Pro-MIG 140 measures 14 inches in height, 10.15 inches in width and 18.6 inches in depth, with a weight of 58 lb. The Handler 140 has a 12-3/8-inch length, a 10-5/8-inch width, a 19-1/2-inch depth and weighs 57 lb.
