Main Switches And Pilot Lamps - Kemppi KempoMat 2500 Operation Instructions Manual

4.4. MAIN SWITCHES AND PILOT LAMPS

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 4000)
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:
The welding voltage is adjusted with two 4-step turn switches
control, where voltage value of each step can be fine-adjusted with the switch
