Weldhead and Torches
For robust solutions for orbital weld applications, the CopperHeads
®
are ideal
cost savers for sanitary and high-pressure tube systems.
The CopperHead series are our most cost effective and rugged in-place
orbital weldheads offered in three models. The CopperHead models 5001
(1/8 - 1 inch OD), 5002 (1/4 - 2 inch OD) and 5003 (1/2 - 3 inch OD) each
offer versatility and high-output production rates.
The water-cooled, narrow profile CopperHeads are lightweight and easy to
handle for those awkward welds with limited access.
All MK weldheads can be utilized as bench mounted or remotely controlled
units.
The models and the capacities are as follows:
MODEL
CAPACITY (Max. OD)
5001
1/8” - 1”
5002
1/4” - 2”
5003
1/2” - 3”
5006
2" OD - 6" OD Tube
With a simple power connector pigtail
(P/N 005-
0619)
, all previously sold MK Orbital weldheads will
adapt to the CobraTig 150 SM. You must change the previous electrode and
ground cable connectors from the push-in type to a twist-lock type.
The order numbers for the twist-lock type are:
P/N 153-0755
Electrode (male
connector to exchange for the black connector) and
P/N 153-0813
Ground
(female connector to exchange for the green connector).
For MicroTig welding operations, the MicroTig Accessory Kit (P/N 005-0670)
is also available. This contains all the necessary items needed when using
the CobraTig
150 SM unit in the WELD MANUAL mode.
Precision MicroTig Technology is a standard feature of the CobraTig150 SM.
The ideal precision manual welder produces reliable, smooth arc starts at 0.5
amps and is perfect for welding precision thin wall exotic materials such as
titanium and stainless steel or fine wire sizes.
