OPERATION
To operate the CobraTig 150 SM portable orbital welding unit, plug in any
standard MK Orbital weldhead to the rear panel, and perform the basic
setup procedures associated with collets, tungsten, and concentricity. Plug
the CobraTig 150 SM into any 120VAC electrical outlet (independent and
isolated circuits will produce the best results), connect the quick disconnect
gas fitting into the unit, and the other end to any argon flowmeter.
Power the unit on by rocking the ON/OFF switch to the ON position (located
on the rear panel - see below). The unit will remember the last screen that
was on when it was powered off. To start from the beginning, it is best to
calibrate the weldhead prior to starting. Once the weldhead is calibrated,
press any button that will return the screen to the MAIN MENU.
From this point use the AUTO PROG button to start designing the weld
procedure, enter the appropriate variables for the material to be welded,
prepare and align material to be welded, check for proper purge gas flow...
Press START.
The CobraTig 150 SM unit will automatically prepurge the gas flow, initiate
the welding arc, perform any tacks if so desired, complete the weld in one or
multiple revolutions depending on procedure design and return the rotor to
home position while the postpurge gas is flowing. Weld complete.
