Model 9 Series Double Clamp Fusion Weld Heads

The Model 9 series of orbital weld heads are designed for fusion (TIG) welding of tube, pipe, fittings or other cylindrical components. Available in ten sizes and three versions, they can be configured over 60 different ways and can accommodate diameters from 3/32” (2,3 mm) to 7.5” (190,5 mm) OD, and wall thicknesses from 0.01” (0,25 mm) to 0.16” (4 mm).

Each weld head fits a wide range of tube sizes via easily replaced, size-specific clamps. The standard Model 9 incorporates a two-sided clamping mechanism to hold components being welded in line and concentric - eliminating the need for tack welding. Several of these heads incorporate a flip-up viewing window, for easy verification of fit-up. Most Model 9 weld heads are plumbed for water cooling of both the cables and internal weld head components - allowing increased duty-cycles.

Compatible with all AMI Power Supplies.
