5-5 Check points prior to use
- Connecting portions must be perfect.
ex) Each portions connecting terminal, cooling water, air pressure system, etc.
- Cooling water & compressed air must be maintained in an even level in
accordance with this manual.
- Remove dirts from air filter.
- Where the variance of input power source is larger, the welding status gets
insecure, so the voltage variance rate should stay in the limit of ±10%.
- The welding transformer should be installed nearby main power source.
(with 30m is suitable).
If the welding transformer is far from the voltage transformer, the voltage drop
become so large that you cannot get the standard current, so care must be taken
- No installation is allowed in such a dangerous places as where the vibration
occurs to impact on the equipment, where the surroundings temperature is over
40
℃
, and where the corrosive and explosive gas comes.
5-6 Caution on Operation
- Prior to power source switch "ON", check out if there is any abnormality in safety
matter of the welding equipment.
- Supply an adequate power to the rated power source of the welding power
source.
- Must be operated after cooling water is supplied.
- The compressed air from the source must be supplied at a standard air pressure.
- In winter, when the temperature reads below 0
℃
, cooling water has to be drained
completely using compressed air, otherwise the cooling water system such as pipe
may be damaged.
- The temperature of cooling water supplied must be below 30
℃
. And the pressure
of cooling water should be more than 1kg/cm
2
at the time of passage.
- You must "OFF" the power source switch for safety when you go away from this
welding transformer even for a moment while operation.
