4.7 Operation Environment
• Height above sea level is below 1000m.
• Operation temperature range:-10°C~+40°C.
• Relative humidity is below 90 %(+20°C). relative humidity
is below 50% (40°C).
• The inclination of the power source does not exceed 10°.
• Protect the machine against heavy rain or in hot circum-
stance against direct sunshine.
• The content of dust, acid, corrosive gas in the surrounding
air or substance can not exceed normal standards.
• Take care that there is sufficient ventilation during
welding. There is at least 30cm free distance between the
machine and wall.
4.8 Operation Notices
• Read section 1 carefully before attempting to use this
equipment.
• Connect the ground wire with the machine directly, and
refer to section 3.
• In the case of closing the power switch, no-load voltage
may be exported. Do not touch the output electrode with
any part of your body.
• Do not watch the arc with no eye protection.
• Ensure good ventilation of the machine to improve duty
ratio.
• Turn off the engine when finished to save power.
• When power switch shuts off protectively because of
failure, don’t restart it until the problem is resolved.
Otherwise, the range of potential problems will be
exacerbated.
