5.7 Plasma welding
5.7.1 Welding torch connection (with gas metering unit GMU)
NOTE
If the plasma and shielding gases are connected via a gas metering unit (GMU), the
connection between the welding machine and the GMU is created using the supplied
gas connection lines with G 1/4" crown nuts connected on both sides.
The GMU can be used for plasma or TIG welding.
Adapters for connecting the welding torch gas connections are screwed onto the GMU
where appropriate.
Before commissioning, the plasma welding torch must be equipped for the welding JOB
and correspondingly set/adjusted!
