6.2 CONTROL FUSES
Fuse F11, 6.3 A delayed, on the rear wall of machine is as protection for connection of auxiliary
devices X14-15.
NOTE! Use same type and rating of fuse which is marked beside the fuse adapter. Damage caused
by a wrong type fuse is not covered by the guarantee.
6.3 UNDER- AND OVERVOLTAGES IN THE MAINS SUPPLY
Primary circuits of machine are protected against sudden, transient overvoltages.
Machine is designed to withstand 3 x 440 V voltage continuously (see technical data). See to
it that voltage is kept within admissible limits especially when mains supply is taken e.g. from
combustion engine generator.
If the mains has undervoltage (under approx. 300 V) or overvoltage (over approx. 480 V)
machine control stops to operate automatically.
6.4 LOSS OF A PHASE IN THE MAINS SUPPLY
Loss of a phase causes noticeable poorer welding properties than normally or the machine
doesn’t get started at all. Loss of a phase can be due to following:
• blowing of mains supply fuse
• defective mains cable
• bad connection of mains connection cable on terminal block or plug of machine
7. DISPOSAL OF THE MACHINE
