AMI Arc Machines Model 8 Narrow Weld Head

The Model 8 series weld heads are orbital heads for fusion TIG (GTAW) welding of fittings, tubing and thin wall pipe. The narrow width of these heads makes it ideal for limited clearance applications, such as welding fitting-to fitting or fitting-to –valve body assemblies. Weld materials such as stainless steel, titanium, Hastelloy and other autogenously weldable alloys.
A key feature of the Model 8 Series weld heads is its unique cooling design, allowing high duty-cycle welding. When connected to an AMI cooling unit, all components of this weld head are liquid-cooled, including cables, clamp housings and electrode rotor.
A variety of clamps are available to perfectly suit every welding application. For fitting-to-fitting or tube-to-fitting welds the standard (narrow) clamps require the least amount of stick-out.
Key Features Include:
- Fabrication shops
- Food, dairy and beverage industries
Biomedical / pharmaceutical installations
Semiconductor fabrication facilities and high-purity piping installations
Vacuum and exhaust fittings
CIP panel construction and valve clusters / headers
Sanitary ferrule and short-tangent weld fittings
- Orbital weld heads for fusion welding of fitting to fitting, fitting to tube, and tube to tube applications
- Narrow head width accommodates most “standard” tube fittings
Highly efficient liquid cooling of both internal and external components allows high duty cycle usage.
