Welding torch connection
NOTE
TIG welding torches to be connected to a Euro torch connector are available in two
versions:
• TIG combi welding torches are connected to the Euro torch connector of the wire feeder
and to the (-) welding current plug of the power source.
• TIG welding torches of the EZA version are connected to the Euro torch connector of the
wire feeder only. To do so, the welding current lead of the intermediate hose package must
be connected to the (-) welding current connection at the rear of the unit!
