Millermatic 255 vs MIG285

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	MIG285
Process	MIG (GMAW), pulsed MIG (GMAW-P), and flux-cored (FCAW). Source	The specifications table says output type MIG, lift TIG, and stick. The overview also names flux core. Source
Output amp range	20–350 A. Source	Max rated output: MIG 285 A, TIG 250 A, stick 250 A. The duty table prints MIG 285 A on 240 V and 120 A on 120 V, and stick and TIG 250 A on 240 V and 120 A on 120 V. Source
Rated duty cycle	230 A at 25.5 V, 60% duty cycle. Source	MIG: 30% at 285 A on 240 V and 30% at 120 A on 120 V. Stick: 30% at 250 A on 240 V and 30% at 120 A on 120 V. TIG: 30% at 250 A on 240 V and 30% at 120 A on 120 V. 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	1-phase, 120 V/240 V. Max inrush (I1max), columns MIG / stick / TIG: 120 V 34.2 / 42.5 / 25.3 A, and 240 V 57.4 / 53.5 / 35.7 A. Max rated (I1eff): 120 V 18.7 / 23.3 / 13.9 A, and 240 V 27.4 / 29.3 / 19.6 A. Source
Wire or rod size	Not published by manufacturer Source	Not published by manufacturer Source
Weight	Machine only: 84 lb. (38 kg). Machine with running gear: 148 lb. (67 kg). Source	The page says “weighing under 60 lbs.” It does not print a single net-weight number. Source
Material thickness	Not published by manufacturer Source	The overview says the 285 A output can weld materials up to 5/8 inch thick. Source
