•
three conducting wires, it does not matter, what is the order of phases
•
the fourth, yellow‐green wire is used for making the „EARTH" connection
Connect a suitable normalized plug to the power cable. Provide for an elect‐
rical socket complete with fuses or an automatic switch.
TABLE 2: Shows the recommended load values for retardant supply fuses
chosen according to the maximum nominal current supplied to the welder
and the nominal supply voltage.
NOTE 1: Any extensions to the power cable must be of a suitable diameter,
and absolutely not of a smaller diameter than the special cable supplied with
the machine.
NOTE 2: It is not advisable to plug up the welder to motordriven generators,
as they are known to supply an unstable voltage.
Control apparatus
PICTURE 1A
Position 1 Supply switch. In the „O" position the welder is off.
Position 2 10‐positional voltage changeover switch.
Position 3 2‐ or 4‐ positional voltage changeover switch.
Position 4 Thermostat yellow signal light. When this light comes it means
that the overheat cut‐off has come on, because the work cycle
limit has been exceeded. Wait for a few minutes before starting
to weld again.
Position 5 Potentiometer of speed adjustment of the wire feed.
Position 6 Switch of spot welding function with potentiometer of adjust‐
ment of spot welding length.
Position 7 Switch of PAUSE function with potentiometer of adjustment of
pause length between each spots ‐ slow pulses and switch of
two‐ and four‐ cycle function.
Position 8 EURO connector of welding burner connection.
Position 9 Inductance connection L1 and L2.
Position 10 Terminal board of voltage supply for gas 42 V AC heating.
Position 11 Supply cable with connection.
Position 17 Automatic electromagnetic gas valve.
