USING THE WELDER
4.1 Basic controls
Main switch
When you turn the on/off switch into position 1, the
main power indicator is illuminated and the welder
system starts a power-up sequence. The system is ready
for use when the setup panel is ready. Always turn the
machine on and off with the power source mains switch.
Never use the mains plug as a switch.
Indicator lights
The indicator lights of the machine report its operational
state: When the green main power indicator is on, it
indicates that the machine is switched on. When the
orange warning indicator light is on, the machine is
overheated. This is due to a higher than regular working
load exceeding the rated duty cycle. The cooling fan
continues to cool the machine down. When the light
goes off the machine is ready to weld again.
Cooling fans
The A7 MIG Power Source incorporates two
simultaneously operating cooling fans. The fans will
start during welding as the machine reaches operational
temperature, and they will run for 1 to 10 minutes after
welding, depending on the heat effect of the completed
cycle.
