3. Check that the earth clamp is connected securely to the work piece and that the
contact point is clean of paint or rust.
1. Duty cycle of the unit has been exceeded. Allow the unit to cool for 20 minutes.
1. Check mains voltage is constant.
2. Check the welding cable connectors are tight in the sockets.

TROUBLE SHOOTING
OPERATIONAL ENVIRONMENT
• Height above sea level ≤1000m
• Operation temperature range -10~+40°C
• Air relative humidity is below 90%( 20°C)
• Preferably sit the machine above floor level, ensure the maximum angle does not exceed 15 degrees.
• Protect the machine against heavy rain and against direct sunshine.
• The content of dust, acid, corrosive gas in the surrounding air or substance must not exceed normal
standard.
• Take care that there is sufficient ventilation during welding. There must be at least 30cm free distance
between the machine and wall.
