Specification

What’s Included
The biggest thing you’ll notice about the PowerMTS 251Si is that the unit really
breaks the mold and doesn’t t well into any MTS category. Yes, it’s DC output
only, but it also features Pulse MIG and Pulse TIG capability to add extra versa-
tility. The unit allows you to save up to 9 programs for instant recall of favorite
settings for fast start up. The unit also can operate on 120V or 240V with ex-
cellent output while operating on 120V. Duty cycle is strong with 40% at maxi-
mum output. It also can accommodate full sized (12”) spools or medium sized
(8”) spools for maximum portability.
