CABLE CONNECTION

!
CAUTION
When this welding machine is used under the circumstance with water, be sure
to adopt waterproof measures in the cable connection position. (If water enters
the connection position, the insulation resistance may decrease or even the
short circuit may occur between connecting lines, thus causing failures.
Be sure to pay attention to the following when connecting cables:
• The length and wire diameter (sectional area) should be selected properly;
otherwise, the welding performance will decrease due to the voltage drop on the
cable.
Therefore, when connecting the extended cable, please note the following:
• The relation between the cable extension and sectional area.
• Shorten the connection cable length as possible.
• When the cable is extended for use, the curling of the cable will be adverse to
the welding performance.
• Try to use single cable and not to lengthen it in the middle.
3-phase connection
The yellow-green wire is used as a PE protective
wire connector. The three phases (black, brown
and blue) can be freely connected to L1, L2 and L3
en (please have it done only by a qualified electri-
cian).
Attention!!!
Welding devices equipped with 400V must be connected by a technician.
