Technical Specifications
Electrical
The CopperHead ® uses a 24VDC motor with TACH feedback. It is controlled
by an orbital power-supply motor-control circuit, to turn the rotor at the
precise speed to create a near perfect weld.

Models
Each weldhead has been designed for optimum performance in specific
applications according to specific diameter ranges. While each weldhead
has a maximum size capacity, it is always best to utilize the next larger
size weldhead when operating near its maximum operating capacity.
Although they may perform satisfactorily in these applications, the maximum
productivity will be achieved where the weldhead is matched to the job. See
Appendix A for reference dimensions of each weldhead.
Model 5001 - CopperHead ® I
The Model 5001 weldhead was designed for precision welding of small
diameter tubes and fittings. The 5001 weldhead is capable of welding 1/8” to
1” OD tubes and associated fittings and 1/8 - 1/2 NP.
Model 5002 - CopperHead ® II
The Model 5002 weldhead was designed for precision welding of small to
medium size diameter tubes and fittings. The 5002 weldhead is capable of
welding 1/4” to 2” OD tubes and associated fittings and 1/8 - 1 1/2 NP.
Model 5003 - CopperHead ® III
The Model 5003 weldhead was designed for precision welding of medium
size diameter tubes and fittings. The 5003 weldhead is capable of welding
1/2” to 3” OD tubes and associated fittings and 1/4 - 2 1/2 NP.
Weldhead Connections
The weldheads come equipped with an
integrated 25’ cable, which connects directly
to the CobraTig
® 150 orbital power-supply
and CobraCooler™. The cable assembly
provides a path for weld power, operator
control and motor signals, inert gas flow,
and recirculating coolant flow (see
Figure 1).
Welding Leads
The two welding Power Leads use a twist-lock type of power connector.
These are designed to attach directly to the rear panel of the CobraTig
® 150.
The male connector connects to the receptacle labeled “ELECTRODE”. The
female connector connects to the receptacle labeled “GROUND”.
