6.1 Indicator Light
The indicator light is provided to indicate when the Transmig is connected to the Mains supply
voltage.
WARNING 3: When the light is lit, the machine is connected to the Mains supply voltage and
the internal electrical components are at Mains voltage potential.
6.2 Standby/Coarse Voltage Control Switch and Fine Voltage Control Switch
The Coarse Voltage Control switch turns off the fan and auxiliary power in the
STANDBY
position.
It sets the voltage level to the welding terminals in the remaining positions, increasing the voltage as
it is rotated in the clockwise direction. The Fine Voltage Control switch increases the voltage (in
smaller increments than the Coarse switch) as it is rotated in the clockwise direction.
WARNING 4: The Coarse & Fine Voltage Control switches MUST NOT BE SWITCHED
during the welding process.
