MK CobraTig® 150

Digital GTAW Orbital Tube Welder

CobraTig® 150 Shown with Optional CobraCooler

Weld Circles Around the Competition!

The portable, lightweight CobraTig® 150 with SmartArc® provides the automatic control you need to deliver repeatability, verification and traceability in high integrity orbital welding.

SmartArc® software develops a near ideal weld procedure through the use of our Automatic Procedure Generator. Just enter the tube OD and wall thickness - the rest is automatic.

The rugged construction of the portable CobraTig® 150 is the perfect package for your construction environments ... and the CobraTig® 150 weighs only 42 pounds (19.1 kg)!

The optional CobraCooler water supply fits tightly under the power supply providing water cooling for any MK weldhead. All CobraTig® 150 systems are shipped in a sealed rugged case with wheels.

Model 254-150 CobraTig 150
Digital Welding Power Source Features

• 150 amps pulsed or constant current stable down to 1 amp.
• High Voltage Pulse automatic arc starting to 25 amps.
• Orbital and manual weld modes of operation.
• (APG) Automatic Procedure Generation, simplifies orbital weld procedure development by creating a near ideal procedure from basic input data such as tube OD and wall thickness.
• Automatic Tacking feature provides up to 7 opposing tack locations around the weld joint circumference.
• Automatic orbital weldhead speed calibration.
• (8) weld levels for smooth current and motor sloping around the circumference plus upslope and final slope.
• Level by level scaling software remembers, and recalculates upon demand, all modifications performed by the operator during the orbital weld resulting in a "new" weld procedure that can be saved for future use if desired.
• LCD display provides automatic light sensor for day or night viewing.
• Integrated high-speed thermal printer provides real-time weld data monitoring and post weld reporting of orbital weld procedure text and waveform graphs.
• Soft-key front panel keypad for user interface.
• Store and modify up to 25 orbital weld procedures.
• Metric and English units for orbital weld data input.
• 3 range manual weld modes, 0-50, 0-100 and 0-150 amp ranges, constant or pulsed.

Data Monitoring and Performance Logging

• Data monitoring of faults detected during the weld sequence, including gas, current, voltage and motor.
• Performance logging of weld parameter text and graphic wave forms, such as current, voltage and motor. For monitoring and logging output deviations from demand values.
