QUICKCLAMP SERIES WELD HEADS
Models 432 & 433
Orbital Weld Heads for Filler Wire Welding of Pipe
Use with Pipemaster Model 515 Power Source
Precision Tools for Precise, Repeatable Welds
The Quickclamp Weld Heads are "full function" with the capability of reproducing all the precise motions of a skilled manual GTAW welder. Both models are specifically designed for multipass pipe welding applications. The Weld Heads consistently produce welds meeting the most stringent code quality standards. The Weld Head is simply slipped over the pipe and clamped with a toggle lever. The continuously adjustable clamp eliminates the need to interchange components when changing pipe sizes. Theses Weld Heads improve productivity by increasing duty cycle, reducing repair rates and producing welds of consistent quality.
Used with all Pipemaster Power Source Models, these weld heads improve productivity by increasing duty cycle, reducing repair rates and producing welds of consistent quality.
The weld head is mounted on the pipe by means of an adjustable toggle clamp. The V-block is quickly adjusted to a new pipe size using an engraved scale. The wide V-block self centers and ensures that the head is squarely mounted relative to the joint. Both Models use a chain drive system with electronic servo speed regulation. The weld head mounts entirely on one side of the joint, allowing use for pipe-to-fitting welds.
The compact Head-mounted wire feeder is electronically controlled for accurate and repeatable filler wire delivery. Both Heads mount standard 0.9 kg (2 lbs.) spools. Multiple adjustments allow precise positioning of filler wire entry into the weld puddle.
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 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 entire actuator can be pivoted to allow socket welding, while maintaining the arc length correction motion along the tungsten electrode axis.
The Heads Drive Systems incorporates heat-tolerant components allowing use on CRMo and other alloys requiring preheat.
