Millermatic 255 vs Handler 125

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 255	Handler 125
Process	MIG (GMAW), pulsed MIG (GMAW-P), 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	20–350 A. Source	25–130 A. Source
Rated duty cycle	230 A at 25.5 V, 60% 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	208–240 V, single-phase. Auto-Line 208–575 V, single-phase. The quick specs do not print input amperes. 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	Not published by manufacturer 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	Machine only: 84 lb. (38 kg). Machine with running gear: 148 lb. (67 kg). Source	57.5 lb. Source
Material thickness	Not published by manufacturer 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
