switching the machine on
When you power on the machine, the green standby indicator and the main switch is lit.
If the machine reaches its duty cycle limit during welding or the supply voltage is too low
or too high, the welding operation automatically switches off and the yellow overheating
indicator light switches on. The light switches off when the machine has cooled and is ready
for operation again. Make sure that there is enough space around the machine to allow fresh
air to freely circulate and cool the machine.
main switch and 'On' indicator
When you turn the main switch to position I, the machine ’ON’ indicator light (item 1) is
illuminated and the unit is ready for welding. The indicator light is always on when the unit is
connected to the mains and the main switch is in position I. In normal conditions the machine
panel ’ON’ lights status is solid green. But if the machine is locked down, the light status is
flashing and the machine will not weld. The machine should be reset via the main switch. If
the light continues to flash, contact your Kemppi service shop.
NOTE! Always start and stop the machine from the main switch, never use the plug as a switch!
indicator 'VrD safe On'
MinarcTig Evo VRD models reduce the open circuit voltage (OCV) at a low level. At switch on,
the VRD indicator light (item 2) is solid green, indicating normal VRD safe limits. If VRD limits
are exceeded the machine switches to 'LOCK DOWN' state and the VRD safe light changes
colour to solid 'RED'. Welding is prevented and the main 'ON' panel light is also flashing. The
machine should be reset via the main switch. If the machine locked status continues, contact
your Kemppi service shop.
