Miller ArcReach® SuitCase® 12 Wire Feeder – Remote Voltage & WFS Control (MR301456)

The Miller ArcReach® SuitCase® 12 Wire Feeder is a rugged, high-performance portable wire feeder featuring game-changing ArcReach® Technology designed to dramatically improve jobsite productivity, safety, and profitability.

By allowing operators to set voltage and wire feed speed remotely at the point of use, ArcReach technology eliminates wasted time walking back to the power source, maximises arc-on time, and ensures consistent weld quality — even on large or multi-level job sites.

Built for harsh industrial environments, the ArcReach SuitCase 12 delivers unmatched durability, reliability, and uptime for demanding field and workshop applications.
