Description
The Arc Machines’ Model 79 series weld heads are economical, easy-to-use, sturdy weld heads designed for precision orbital welding – with or without filler wire – of tube, pipe, and fittings.
Each Model 79 weld head features Arc Voltage Control (AVC) for precise arc gap control, programmable oscillation (weaving) and a precision wire feeder and wire entry mechanics. All Model 79 weld heads operate using the GTAW (TIG) process and will accommodate a range of pipe sizes from 0.75″ OD to 6.625″ OD (19 mm to 170 mm) and wall thicknesses up to 0.75″ (19 mm).
Please call to discuss your application and arrange a demonstration.
