• MK Edit/SmartArc Weld Program Editor and latest CobraTig Firmware,
downloaded and saved to the Desktop.

not exist on the PC/laptop.
2. Once cabling is connected, on the CobraTig front panel, press and
hold the F10 button (lower-right hand button) while powering on the
CobraTig.

not, turn CobraTig off, wait 15 seconds and try again.

Upgrade to CobraTig (Ctrl + U).
Choose the correct COM port, in accordance with your PC/laptop, from
the CobraTig Communication dialog box. Press Start.

CobraTig Communication Dialog box.*
