C-SERIES WELD HEADS
Models 819A, 821A, 822A, & 823A

Orbital Weld Heads for Fusion Welding of Tube and Pipe

Use with
  • Tubemaster Model 514A Power Source
Precision Tools for Precise, Repeatable Welds

The C-Series are easy-to-operate tools for autogenous tube welding. Four models cover tube size range from 3mm-114mm (0.125"-4.5") O.D. Magnatech C-Series Heads make tube-to-tube and tube-to-fitting welds with precision and repeatability.

The double-clamping design simplifies work piece fit-up and eliminates tack welding in many cases. Collets are available for any tube and fitting size.

Digital technology forever eliminates the need for periodic weld Head calibration - rotation speed remains accurate regardless of Head wear, and Heads can be interchanged without time-consuming recalibration.

 
Applications
  • Semiconductor/High Purity
  • Pharmaceutical
  • Sanitary (Hygienic) Process Pipe
  • Aerospace
  • Medical/Biotechnology
  • Food Processing/Dairy
  • Brewery
  • Instrumentation
Features
  • Collets for all tube size/fitting geometries
  • Detachable cartridge simplifies fit-up and clamping
  • Waterproof carry case standard
  • Internal Weld Head cooling standard
  • Glass view port allows final inspection before welding
  • Unique insulated collets and cartridges prevent internal "arc over"
  • Encoder motors provide precise, repeatable speed regulation
  • Encoder motors provide "jam" protection. If rotation motor stops for any reason, it is instantly sensed and power to the motor is immediately interrupted. No more damaged motors or drive trains.
Different Collet Types Available
  • Flush collets for minimal axial clamping length
  • Extended collets for maximum alignment capability
  • Mixed sets (one side flush, one side extended). Ideal for tube-to-fitting welds. Flush clamping on fitting side, with extended clamping on tube side.
  • Counterbored flush collets further reduce required axial clamping length (special)
Options
  • Extension cables allow use up to 23 meters 975 fett) from power supply
  • Pre-ground tungsten electrodes
  • Bench Mount Bracket firmly retains weld Head
  • Offset Tungsten Holders (Butt weld) allow use when axial clearance restrictions exist (such as short tangent fittings)
  • Offset Tungsten Holders (Fillet weld) allow fillet (socket) welds to be made
  • Manual tack welding kit includes water-cooled torch with quick disconnect adaptor fittings
