Model 8 Series Weld Heads

Where To Buy
Inquire about this product

The Model 8 series orbital weld heads are designed for fusion (TIG) welding of tube, thin-wall pipe and fittings through the range of 0.25 in. (6 mm) to 6.625in. (168 mm) OD (outside diameter) and wall thicknesses up to 0.160in. (4 mm). The narrow width of these heads makes them ideal for fitting-to-fitting welds and other limited-clearance applications.

The Model 8 series weld heads incorporate a two-sided clamping mechanism - precision machined and designed to compensate for significant diameter variances while ensuring positive clamping force and concentricity. The insert sizes accommodate an extensive range of applications and all Model 8 series weld heads are fitted with water-cooling capability - for heavy wall material welding and/or high duty-cycle requirements.

  • Fitting support mandrel - to facilitate the welding of short sanitary ferrules without pre-tacking
  • Bench mount bracket - to provide secure support when not in use or when bench welding
  • Clamp inserts - available in imperial and metric sizes, as well as non-standard sizes for custom applications
  • Extension cables - available in 25 ft. (7.6 m), 50 ft. (15.2 m), and 75 ft. (22.8 m) lengths
