Fusion Orbital Welding Machines

Power Supply

Model 205 is the most advanced, easy-to-use orbital (GTAW) power supply in the industry - capable of welding tube, thin-wall pipe, and fittings from 3/32" (2,3 mm) through 7.5" (190,5 mm) OD, in wall thicknesses up to 0.160" (4 mm).

Model 207 is a 100/150 A programmable GTAW power supply. It is designed to work with all AMI’s orbital fusion weld heads and is capable of welding tubing and thin wall pipe.

Weld Heads

Model 8 Series weld heads are orbital weld heads for fusion (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. Welds materials such as stainless steel, titanium, Hastelloy™ and other autogenously weldable alloys.

Model 9 Series 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).

The Model 4 Benchtop is a fully integrated orbital tube weld head with an available component support and position tooling plate. The Model 4-500 is designed for high-production bench welding of tubing, fittings, valves and other small component assemblies.

Model 21 Series AMI Model 21 weld heads bring a new level of quality and efficiency to your fusion welding process. Designed for fusion (TIG) welding of tubes through the range of 0.125” (3,175 mm) to 1” (25,4 mm) OD. The compact, robust design of the heads makes them ideal for restricted clearance applications.
