Miller Weldcraft WP-17 Torch Body

The Miller Weldcraft WP-17 is an air-cooled TIG torch body rated for 150 amps at a 60 percent duty cycle. It suits welders working in aerospace, fabrication, maintenance, metal art and petrochemical repair. The torch accepts electrode diameters from 0.02 inches up to 1/8 inch for versatile welding tasks.

Air-Cooled 60 Percent Duty Cycle Limit

Air cooling restricts continuous output to 150 amps at a 60 percent duty cycle, meaning the torch must rest four minutes out of every ten at full current. Higher amperage or longer runs demand a water-cooled alternative. The design includes no built-in gas valve, so flow control relies on the power source or a separate valve.

150 Amp Maximum Current Rating

The 150 amp ceiling is the single figure that decides fit: jobs needing more continuous current require a larger torch or liquid cooling. This body covers most thin-to-medium plate work but cannot sustain heavy industrial loads. Proposition 65 warnings apply for California users regarding cancer and reproductive harm.

Questions about this item

Should I choose the WP-17 or a different torch body for my application?

The WP-17 body is rated 150 A at 60 % duty cycle, air-cooled, and handles electrodes from .02 in to 1/8 in for aerospace, fabrication, food and beverage, maintenance, metal art, petrochemical and shipboard work.

What does the 150 A rating mean when I am actually welding?

It means the torch can carry 150 amps continuously for six minutes out of every ten; beyond that the air-cooled head needs time to shed heat before you resume.

What connection standard does the A-150 series use and what does it limit?

The A-150 series uses the industry-standard A-150 connection, which caps compatible consumables and power cables to those built for the same series.
