| D-HEAD
MODEL 420
The model D weld Head is capable of reproducing all
the precise motions of a skilled manual GTAW welder. It is
specifically designed for multipass pipe welding
applications and consistently produces welds meeting the
most stringent code quality standards.
Used with Pipemaster Power Source Models, the D-Head
improves productivity by increasing duty cycle, reducing
repair rates and producing welds of consistent quality. The
compact head is ideal for smaller diameter pipe applications
with limited radial and axial clearance around the weld.
The D-Head mounts on the pipe by means of metal Guide
Rings, which are available for all standard pipe/tube sizes.
The weld Head mounts entirely on one side of the joint,
allowing for pipe-to-fitting welds. The compact head-mounted
wire feeder uses standard size wire spools.
The D-Head drive system incorporates heat-tolerant
components and a water-cooled housing for use on CrMo and
other alloys requiring preheat. Mounting the head on an
oversize Guide Ring with adapter feet creates an air space,
preventing heat damage.
