5.8.16
Standard MIG/MAG torch
The MIG welding torch trigger is essentially used to start and stop the welding process.
Operating elements
Functions
Torch trigger
• Start/stop welding
Other functions are also possible by tapping the torch trigger, depending on the machine type
and control configuration:
• Change over between welding programs (see "Program changeover with standard torches (P8)"
chapter).
• Program selection before starting welding (see chapter entitled "Selecting programs with the standard
torch trigger (P17)").
5.8.17
Remote control
CAUTION
Damage to the machine due to improper connection!
The remote controls have been developed to be connected to welding machines or wire
feed units only. Connecting them to other machines may cause damage to the
machines!
• Observe the operating instructions for the welding machine or wire feed unit!
• Switch off the welding machine before connecting!
The operation of the remote control and its settings are directly dependent on the configuration of the
respective welding machine or wire feed unit. The settings are defined by changeover switches or by
setting special parameters (dependent on the control).
• Infinitely adjust wire feed speed and arc length correction (welding voltage) (the function is only
available in program 0). Switch the “welding torch function” changeover switch to the program position.
Special functions
• Adjust wire feed speed and arc length correction within defined limits.
The function can only be enabled in connection with an M3.7x machine control.
Special parameter P7 must be switched on (see corresponding documentation).
The function can be used in all programs except program 0.
5.8.18
MIG/MAG automatic cut-out
NOTE
The welding machine ends the ignition process or the welding process with an
• Ignition fault (no welding current flows within 5 s after the start signal).
• Arc interruption (arc is intrerupted for longer than 3 s).
