ST WELD MINI-160, Инструкция по эксплуатации

Страница: 43 / 45

- Blow the dust with dry air regularly. Operator need remove the dust very day if welding in dense smoke
and serious polluted air.
- The air flow should be in reasonable pressure, too strong flow will destroy some small components.
- Avoid water or steam into the machine. Operator needs to dry the machine when this situation happed.
Then to measure the insulation with an ohmmeter. Ensure everything is OK, then start to welding.
- Packing up the machine to relatively dry environment if not using frequently.
WARNING! Blind experiments and imprudent overhaul may lead to the expansion of the area of the fault,
cause difficulties to the formal overhaul. The equipment in an energized state machine within the exposed
part with can lead to dangerous voltage, any direct or indirect contact may lead to electric shock accidents,
serious electrical shock will result in death!
Note : During the warranty period, the user repairs without authorization or error repair, the free repair
warranty provided by the suppliers will be invalidated.
TROUBLESHOOTING
The phenomenon you meet here may have connections with spare parts, welding materials, environment
and supply power, please take measures to avoid those things.
1. Hard to start arc, easy to break arc
- Make sure the welding electrode good quality.
- The electrode without dealing with drying process may cause arc unstable, bad welding quality.
- The output voltage will decrease when using longer output cables. It's suggested using shorter output
cables.
2. Output current cannot meet the rated value
- Unrated power supply will cause output value not match the rated value data.
3. The current not stable during welding process
- This situation may cause by the following:
•
The supply voltage not stable.
•
Disturbed by the supply voltage
4. More sparks
- Using small electrode with high current adjusted.
- The output polarity reversed.
