Description

The patented PT-37 torch severs up to 1-1/4 inch material using air as the plasma and shielding gas. Utilizing a blowback
start and an electronically controlled pilot arc the PT-37 sets a new standard for starting reliability, cutting characteristics
and consumable life.
This manual is intended to provide the operator with all the information required to assemble, operate, and repair the PT-
37 Plasma Arc Cutting Torch. For additional safety precautions, process instructions, and system troubleshooting; refer to
the appropriate instruction manual for your Plasma Arc Cutting Package.

ply.
• Machined torch body with 1-3/8" (35mm) metal handle, available with and without 32-pitch rack to fit industry
standard torch holders.
