When spatters or iron particles get into the welding power source, turn off the power switches of the welding power
source and power distribution box, and then blow out.
.
Notice: In order to get better performance and provide proper maintenance,
please follow the below instructions:
1 If welding machine is placed on a slope, a countermeasure should be taken to
keep it from falling on one side.
2 The degree of protection is IP21S, appropriate coverage is required in case of rain.
3 When using forklift, please fork welding machine at the side with “Fork” mark to avoid falling.
4 When using hoisting machine, please fasten cordage in the rings on the top of welding machine
and make the angle Φ across the cordage and perpendicular shown in the drawing not more than
15 degrees.

Cautions about electromagnetic disturbance
●
Extra precaution may be required when welding power source is used in a domestic establishment.
●
Before installing welding equipment ,the user shall make an assessment of potential Electromagnetic problems in
the surrounding area as below.
a)
Other supply cables, control cables, signaling and telephone cables; above, below and adjacent to the welding
equipment;
b)
Radio and television transmitters and receivers;
c)
Computer and other control equipment;
d)
Safety critical equipment, e.g. guarding of industrial equipment;
e)
The health of the people around , e.g. the use of the pacemaker and hearing aids;
f)
Equipment used for calibration or measurement;
g)
The immunity of other equipment in the environment; the user shall ensure that other equipment being used in
the environment is compatible; this may require additional protection measures;
h)
The time of day that welding or other activities are to be carried out.
●
The user shall be observe to reduce emission disturbance as below.
a)
Welding equipment should be connected to mains supply according to the manufacture’s
recommendations.
b)
Welding equipment should be routinely maintained according to the manufacture’s recommendations.
c)
The welding cables should be kept as short as possible and should be positioned
close together, running at or close to the floor level.
d)
Confirm to connection of all metallic components in the welding installation and adjacent to it should be
considered for safety.
e)
The work-piece should be connected to earth for electric safety.
f)
Selective screening and shielding of other cables and equipment in the surrounding area
may alleviate problems of interference. Screening of entire welding installation may be considered for special
applications.
The user should take the responsibility with respect to interference from welding.
