Model 79 Series, Full-Function Weld Heads0 pages
The widest range of orbital welding equipment in the world
The Model 79 series of high durability, “full
function” weld heads are designed for fabrication
shop and field process pipe welding applications.
The Model 79 weld heads have a unique integral
clamping system which gives each weld head the
ability to adjust for different pipe and tubing
diameters in seconds, thereby eliminating the
requirement for specific sized guide rings.
The M79 weld head series can 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).
FEATURES
Arc Voltage Control (AVC) for precise arc gap control.
Programmable oscillation and precision wire feeder with
wire guide positioned.
Integral clamping system with the ability to adjust for
different pipe and tubing diameters in seconds.
Clamping mechanism allows automatic centering of the
weld head on the pipe.
Water cooled torch for 100% Duty Cycle operation.
