*Operating cycle: shows the period, within which the machine can generate corresponding current. It
is expressed in %, based on 10 minutes per cycle e.g.: 65% = 6 minutes and 30 seconds of operation,
3 minutes and 30 seconds of waiting).
Installation place
Install the machine in such a way so that ventilation openings are not obstructed (forced circulation).
Do not allow aggressive steam, dust, humidity etc., inside the machine.
Connecting the machine to the supply line
Install the plug which meets standards on the feeding cable. The plug must be equipped with ground
tip, which must be connected with yellow-green cable. Prepare the receptacle which meets standards.
The receptacle must be equipped with a fuse or an automatic circuit breaker. From table 1 determine
recommended nominal of the fuse at maximum rated consumed current and rated line voltage.
Table 1
Before connecting ensure that voltage, indicated on the machine nameplate, complies with
the voltage and frequency of the mains.
Connecting welding cables
Any connection to the welding circuit must be performed when the machine is disconnected from the
supply line.
Welding cable with electrode holder
is connected to the positive pole (+) (see «Welding»).
Cable with functional terminal is connected to the negative pole (-), its other end is connected to the
piece to be welded or operating area as close to the welding seam as possible.
WARNING! Connected cables must be inserted securely in the terminals, which will
ensure good contact. Loose connections will lead to overheating, timely wear, loss of
efficiency and damage to the terminals. Do not use welding cables of more than 5 m
in length.
Never use metallic constructions which are not the part of the piece to be welded instead of
cable with functional terminal, as this will violate safety and lead to poor welding.
