3.17 MMAW (STICK) Dead Man Switch Mode
A special trigger mode called “Dead Man Switch” mode is available on the 220AC/DC and 300AC/DC when
welding with MMAW (STICK) electrodes. In this mode, there will be no output voltage at all from the Power
Source until the trigger is pressed. This provides the greatest level of safety for the operator, and is mandatory
on some work sites.
While the Dead Man Switch function greatly increases operator safety, standard welding safety procedures
should still be followed.
When the trigger is pressed, the VRD voltage is activated and the user can start welding as normal. For extra
safety, if welding has not commenced within 3 seconds after the trigger is pressed, the Power Source will
turn off the VRD, and the trigger must be released & pressed again to start welding.
If the trigger is released during welding, all welding power is shut off within the time limits of normal VRD
operation.
A special MMAW (STICK) electrode holder is required for use with a Power Source fitted with the Dead Man
Switch function. This electrode holder has a trigger switch attached to it, and a control cable that connects to
the remote control socket of the Power Source.
The Dead Man Switch function is active in both 2T and 4T MMAW (STICK) mode.
