Model 9 Series Fusion Weld Heads

Product catalog summary

Overview of Orbital Welding Equipment:
The document provides detailed information on the Model 9 series of orbital weld heads designed for fusion (TIG) welding of tubes, pipes, fittings, or other cylindrical components. These weld heads are available in eight sizes and three versions, accommodating 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). They are compatible with all AMI Power Supplies and feature a two-sided clamping mechanism to maintain alignment without tack welding.

Conversion Kits:
Model 9 series weld heads can be converted to alternate configurations using conversion kits, which require only a screwdriver and a hex wrench for installation, taking 5 to 10 minutes.

Specific Models:

Model 9-250: Designed for precision orbital GTAW (TIG) welding of up to 1/4” (6.35 mm) OD tubing with tight radial clearance limitations.
Model 9-500 & 9-500C: Suitable for components with short stick-out, with the 9-500C offering water cooling for higher duty cycles.
Model 9E Series: Designed for tubes or thin-wall pipes with diameters from 0.25” (6.3 mm) to 6.625” (168.3 mm) OD, featuring single-sided clamps and gas seals.
Model 9CT Series: Available in three sizes for tubes or thin-wall pipes from 0.093” (2.3 mm) to 1.50” (38.1 mm) OD, with removable cassette modules for alignment and holding.

Accessories:
Includes fitting support mandrels, purge mandrel tools, tungsten electrodes, off-set electrode holders, and various other accessories to enhance functionality and adaptability.

FUSION (GTAW) WELD HEADS The widest range of orbital welding equipment in the world The Model 9 series of orbital weld heads are designed for fusion (TIG) welding of tube, pipe, fittings or other cylindrical components. Available in eight sizes and three versions, they 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. These weld heads are compatible with all AMI Power Supplies. 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. Conversion Kits To enhance versatility, many Model 9 series weld heads may be converted to an alternate configuration by installing a conversion kit. The conversion takes 5 to 10 minutes, using only a screwdriver and a hex wrench. www.arcmachines.com [email protected]

S FUSION (6TAW) WELD HEADS The Model 9E series weld heads are designed for fusion (TIG) welding of tube or thin-wall pipe through OD. It's available in five sizes to weld components that do not provide enough stick-out for a double- clamp set up. An off-set electrode, single-sided clamp and gas seal make the Model 9E series weld heads adaptable to a wide variety of applications, e.g. pipe fitting and short sanitary ferrules. Clamp inserts and gas seals are available for all standard sizes as well as for custom applications. Available in three sizes, the Model 9CT (Cassette Type) series weld heads...
