· Safety Precautions
· Before using this product, please read the User's Guide and the manual of the machine attached with it.
· This product must be installed or operated by professionally trained personnel.
· Please keep away from the arc welding equipment to avoid the electromagnetic wave from interfering with the
controller.
· Please do not use it at room temperature above 45°or below 0°。
· Please do not use it in places with humidity below 30% or above 95% or where there is dew and acid mist.
· When installing the control box and other parts, turn off the power and unplug the power plug.
· To prevent interference or electric leakage accidents, make a good grounding work. The grounding wire of the
power cord must be firmly connected to the earth.
· All parts for maintenance must be supplied or approved by the Company before they can be used.
· The power must be turned off and the plug unplugged before any maintenance action is performed.There is a
high-voltage danger in the control box. You must shut down the power for 5 minutes before opening the control
box.
