The T-Head model weld heads (Models 416 & 418) are "full function" - with the capability of reproducing all the precise motions of a skilled manual GTAW welder.  They are specifically designed for multipass pipe welding applications.  These weld heads consistently produce welds meeting the most stringent code quality standards.  The T-Heads are ideal for larger diameter/heavy wall pipe welding requirements.

Used with the Pipemaster Power Source Models, these weld heads improve productivity by increasing duty cycle, reducing repair rates and producing welds of consistent quality.

The T-Head is a rugged head for larger diameter / heavy wall applications requiring precise welding process control of GTAW.

The weld head is mounted on the pipe by means of metal Guide Rings (patented), which are available for all standard pipe / tube sizes.  The weld head mounts entirely on one side of the joint, allowing use for pipe-to-fitting welds.

FLX-Track® allows long linear seam welds on flat or curved surfaces, such as tanks and vessels requiring precision GTAW welding.  FLX-Track allows ID, OD, and compound curvature welds to be made.  Standard 2.3m (7.5') track sections quickly interlock to form longer lengths and mount on the workpiece using magnet, vacuum, or stud-gun attachment.  The track flexes to conform to different diameters, eliminating the need to purchase special tracks for each new application.  (For Model 418 only)

The width and speed of the torch oscillation stroke are independently programmed.  Torch "Dwell" is independently adjustable at both oscillation stroke end points.  A "Cross Seam Adjustment" steering control on the remote Pendant allows the welder to track the torch on the weld seam without the need for manual adjustments near the arc.  Pulsed current is automatically synchronized with torch oscillation when both functions are operated simultaneously.

The Arc Gap Control electronically maintains a desired arc length as the torch rotates around the pipe.

The T-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.
