Same fields. Each cell is that model's published text. A blank stays "Not published by manufacturer." The outlet chip does not hide either column.

Spec	Millermatic 142	Handler 125
Process	MIG (GMAW) and flux-cored (FCAW). Source	Flux-cored out of the box, and MIG after a regulator and shielding gas are added. The sheet calls it a constant-voltage DC welder. Source
Output amp range	30–140 A. Source	25–130 A. Source
Rated duty cycle	100 A at 19 V, 60% duty cycle. 80 A at 18 V, 100% duty cycle. Source	80 A at 25% duty cycle. The specifications table also prints 50 A at 60% and 40 A at 100%. Source
Input voltage and plug	120 V, 20 A, single-phase, 50/60 Hz. Source	120 V. Amps input at rated output, 60 Hz: 21.3 A. The sheet says it operates on common 120-volt power and includes a power cord with plug. It does not name the plug or a breaker size. Source
Wire or rod size	Set up for .024–.035 in. (0.6–0.9 mm) solid wire and .030–.045 in. (0.8–1.2 mm) flux-cored wire. Uses 4- or 8-inch spools. Source	Ready to weld with .030–.035 in. (0.8–0.9 mm) self-shielding flux-cored wire. With gas, .023–.030 in. (0.6–0.8 mm) solid wire. Stainless wire is mentioned for 18–12 gauge stainless with tri-mix gas. Source
Weight	33 lb. Source	57.5 lb. Source
Material thickness	Steel: 24 ga.–3/16 in. single pass. Aluminum: 18–14 ga. single pass. Source	Mild steel thickness range 24 ga.–3/16 in. The same page limits the gas-shielded example to 24 gauge–1/8 inch steel. Source
