Maintenance
In order to use safely, periodical maintenance and repair should be carried out. When examining the
interior and exterior connection ends, the primary distribution box must be cut off. (or take the
fuses away)
a. Daily Notices
(1) There are abnormal vibration, sound, smell or not;
(2) There are abnormal heat at the cable connection or not;
(3) When the switch of power source is turned on, the cooling fan of the machine rotates agilely or not;
(4) Switches contact well or not;
(5) Cables are cut off or not;
b. Examine Items Once for 3-6 Months
(1) Electric connection
The bolts of the connection at the input and output sides of the welding machine are loose or not. There
are contact problems due to the rusts and insulation problems or not.
(2) Grounding wires
The cover of the machine is connected with ground safely or not.
c. Eliminate the dusts inside the welding machine
The dusts deposited on the cooling board of thyristors will cause bad heat dispersal and bring adverse
influence. The dusts deposited at the windings of the transformer will cause insulation deterioration. So,
the examination should be carried out every half year, demounting the side board and top cover, using
the dry compression air to clean the related parts.
d.High frequency adjustment
Generally, don’t touch the spark electrode (the spark gap is 1 mm normally). When the surface of
electrode isn’t flat and has notable feculences, it should be burnished, and adjust the electrode gap to 1
mm.
e.Examination Points for Abnormal Action
e1. No arc initiation, No high frequency
(1) The fuse of control circuit melts;
(2) The high frequency fuse melts;
(3) The spark gap is too large or is shorted;
(4) The cable of torch’s switch breaks off;
(5) Turn the conversion switch of welding methods to “Stick welding”;
E2. High frequency is ok, but no arc initiation
(1) Forget to connect the cable to the mother-material or it is not connected perfectly.
(2) The cables of the welding torch and mother-material breaks off;
