Connection assignment, welding torch control cable
TIG welding machines are equipped ex works with a dedicated connection socket for the welding torch
control cable (5- or 8-pole). As mobile machines offer more free space, they may even feature two control
cable connection sockets. The functionality increases with the number of poles. One of these connection
sockets may be converted or retrofitted
