Prior to starting to first use the machine, the power supply connection
has to be verified. Across any two phases (L1-L2, L2-L3, L1-L3) a volt-
age of 400 V AC ± 10 % has to be found. If a neutral is wired to the same
power supply socket, across any of the three phases and the neutral, a
voltage of 230 V AC has to be found. These measurement can be take
with any common voltmeter for alternating current voltages.
If connected appliances are equipped with a motor requiring 3-phase
alternating current supply, as is the case with the SP 315-S, the rotating
field of the machine has to have the proper direction. The SP 315-S checks
this and if the rotation is incorrect, a “Power Supply Error” message is
displayed. To change the direction of the rotation of the field, the phase
inverter in the plug can be used. Two of its contact pins are placed on
a grey turning disk. A flathead scredriver can be used to turn this disk,
thereby inverting the positions of the two pins, which in turn inverts the
rotation of the field.
3.3 Welding Process Overview
The welding process is performed as follows:
s 0IPES ARE CLAMPED INTO THE FRAME DEPENDING ON THE FORM OF THE
component to be welded, this may mean that the outer clamps have
to be re-adjusted or that reducer inserts have to be inserted.
