Miller Weldcraft WP-18 TIG Torch Kit
This water-cooled TIG torch kit belongs to the W-350 series and is rated for 350 amps at a 100 percent duty cycle. It is built for professional welders who need continuous high-amperage GTAW performance with a rigid neck and built-in fingertip gas control.
Water-Cooled Torch Limits
The water-cooled design sustains the full 350-amp rating only when a compatible recirculator provides adequate flow and temperature control. Without sufficient cooling capacity the torch cannot maintain its 100 percent duty cycle and may overheat during extended welding runs.
Electrode Range Decides Fit
The torch accepts tungsten electrodes from .02 inch up to 5/32 inch diameter, covering the standard range for precision and heavy GTAW work. If your application requires electrodes outside this range a different torch head or collet body will be necessary.

Questions about this item
Should I pick the 25 ft length or another length for the WP-18-25-R kit?
The WP-18-25-R is supplied as a 25 ft water-cooled TIG torch kit rated 350 A at 100 % duty cycle, with a rigid neck and built-in fingertip gas control.
What does the 350 A rating mean when I am welding?
The torch is rated for 350 A maximum current at 100 % duty cycle, so it can sustain that output continuously while the water cooler is running.
Which cooling standard does the water-cooled torch follow and what does it limit?
It uses a water-cooled design compatible with the W-350 series, enabling the 350 A 100 % duty-cycle rating and electrode range of .02 in to 5/32 in.
