Miller W-375 TIG Torch Kit
This Miller W-375 TIG torch kit handles 375 A at a 100 percent duty cycle for continuous high-amperage work. The rigid neck and .020 to 1/8 in electrode range suit precision fabrication shops and vocational programmes. It is built for aerospace, shipbuilding and pressure-vessel applications that demand steady output.
375 A 100% Duty Cycle
The 375 A rating at 100 percent duty cycle is the single figure that decides fit: the torch will not overheat during long production runs at full power. If your process requires higher amperage or a flexible neck, this model will not meet the requirement. Buyers who need water-cooled operation or a different duty-cycle profile should look elsewhere.
Ready for GTAW Tasks
The kit arrives configured for TIG welding (GTAW) across aluminum, exotic alloys, pipe and tube work. No separate consumables pack is mentioned, so operators must source electrodes, collets and gas lenses matched to the .020-1/8 in range. This keeps the setup focused on immediate production use.

Questions about this item
What does the 375 A rating at 100 % duty cycle mean for continuous welding?
The torch can sustain a 375 A output without interruption, so it handles long production runs on thick aluminium or stainless without overheating.
Which power-source connection does the W-375 series use and what amperage does that connection support?
The W-375 series connects via a standard TIG torch fitting rated for the torch's full 375 A capacity, so the interface does not limit the current.
What electrode sizes fit the 0.020 in to 1/8 in collet range and how is the rigid neck mounted?
The collet body accepts electrodes from 0.020 in up to 1/8 in, and the rigid neck bolts directly to the torch body for a fixed working angle.
