3. Safety precautions
WELDING CAN BE HARMFUL TO YOURSELF AND OTHERS.
The user must therefore be educated
against the hazards, summarized below, deriving from welding operations. For more detailed information, order
the manual.
ELECTRIC SHOCK
- May be fatal.
Install and earth the welding machine according to the applicable regulations.
Do not touch live electrical parts or electrodes with bare skin, gloves or wet clothing.
Isolate yourselves from both the earth and the work piece.
Make sure your working position is safe.
FUMES AND GASES
- May be hazardous to your health.
Keep your head away from fumes.
Work in the presence of adequate ventilation, and use ventilators around the arc to prevent gases from forming in
the work area.
ARC RAYS
- May injure the eyes and burn the skin.
Protect your eyes with welding masks fitted with filtered lenses, and protect your body with appropriate safety
garments.
Protect others by installing adequate shields or curtains.
RISK OF FIRE AND BURNS
Sparks (sprays) may cause fires and burn the skin; you should therefore make sure there are no flammable
materials in the area, and wear appropriate protective garments.
NOISE
This machine does not directly produce noise exceeding 80dB. The plasma cutting/welding procedure may
produce noise levels beyond said limit; users must therefore implement all precautions required by law.
PACEMAKERS
The magnetic fields created by high currents may affect the operation of pacemakers. Wearers of vital electronic
equipment (pacemakers) should consult their physician before beginning any arc welding, cutting, gouging or spot
welding operations.
EXPLOSIONS
Do not weld in the vicinity of containers under pressure, or in the presence of explosive dust, gases or fumes. . All
cylinders and pressure regulators used in welding operations should be handled with care.
ELECTROMAGNETIC COMPATIBILITY
This machine is manufactured in compliance with the instructions contained in the harmonized standard
，
and must
be used solely for professional purposes in an industrial environment. There may be potential difficulties in
ensuring electromagnetic compatibility in non- industrial environments.
IN CASE OF MALFUNCTIONS, REQUEST ASSISTANCE FROM QUALIFIED PERSONNEL.
4. Trouble shooting
The machine with three protection function. If the machine is abnormal, please refer to the following:
1)
Over heat protection
There is a aux transformer inside the machine. The aux transformer is with thermal switch. The temperature
of the transformer will rise following the machine work duty. If the machine is over duty and over heat,
the“auto”and “manual” indicator on front will light up, the machine will stop output. In general, the machine
duty cycle is enough to car body repair. If the machine over heat protection on low work duty, please check
the fan.
