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 | Maxstar 161 STH | MIG285 |
|---|---|---|
| Process | Stick (SMAW), Lift-Arc TIG (GTAW), high-frequency TIG (GTAW), and pulsed TIG (GTAW-P). High frequency and pulse are marked STH model only. | The specifications table says output type MIG, lift TIG, and stick. The overview also names flux core. |
| Output amp range | 120 V: 5–130 A DC TIG and 20–90 A DC stick. 240 V: 5–160 A DC TIG and 20–160 A DC stick. | 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. |
| Rated duty cycle | TIG, 120 V: 90 A at 13.6 VDC, 100% duty cycle, and 130 A at 15.2 VDC, 30%. TIG, 240 V: 110 A at 14.4 VDC, 100%, and 160 A at 16.4 VDC, 20%. Stick, 120 V: 60 A at 22.4 VDC, 100%, and 90 A at 23.6 VDC, 30%. Stick, 240 V: 110 A at 24.4 VDC, 100%, and 160 A at 26.4 VDC, 20%. | 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. |
| Input voltage and plug | 120–240 V, 1-phase. Amps input at the higher duty-point ratings: TIG 22.6 A at 120 V and 15.05 A at 240 V; stick 23.16 A at 120 V and 22.55 A at 240 V. Separate 120 V and 240 V power cords are included. | 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. |
