main switch (Kempomat 2500 and 3200)
In zero position all control and welding current circuits of the equipment are dead (without
voltage). In position I the control circuits of the machine become live (get voltage). The
primary and welding circuits are dead, if the welding mode has not been started with the gun
trigger.
main switch (Kempomat 4200)
In zero position all control and welding current circuits of the equipment are dead (without
voltage). In positions 15 - 28 V and 28 - 48 V the control circuits and cooling fan of the
equipment get voltage. The primary and welding circuits are dead, if the welding mode has
not been started with the gun trigger.
Always switch on and switch off the machine from the main switch. Never use the mains plug
for switching on or switching off the units and equipment!
adjustment of welding voltage
Table of adjustments, switch positions:
In Kempomat 2500 the welding voltage is adjusted with one 10-step turn switch. In
Kempomat 3200 and 4200 the welding voltage is adjusted with two turn switches. In
Kempomat 4200 first select the other welding voltage area from the main switch
is 4-step switch for coarse control, where voltage value of each step can be fine-adjusted
with the switch
Kempomat 4200 230V with 4-steps, and in Kempomat 4200 400V with 7-steps.
