USING THE WELDER
4.1 Basic controls
Main switch
When you turn the on/off switch to position 1, the main
power indicator is illuminated, and the welding system
starts a power-up sequence. The system is ready for use
when the control 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 indi-
cates 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 exceed-
ing 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 A3 Power Source incorporates two simultaneously
operating cooling fans. The fans will start during weld-
ing 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.
