13. User guide on equipment installation
a) Should be installed in indoor environment where is no direct sun light and can protect products against raining, high humidity and dust. (humidity range: -10℃~+40℃).
b) Ground gradient: less than 15°.
c) Welding booth should avoid violent wind.
d) Welding Machines should be installed 50cm away from the wall.
e) Corresponding switch board or closet is a necessary and three-phase 380V/50Hz AC should be linked to input cable junction box through air switch and then linked to the earth wire correctly.
f) Anode output cables should be used to link welding source and welding torch.
g) Cathode output cables should be used to link the cathode of welding source and work pieces need to be welded.
h) Controlling cables should be used to link automatic Welding Machine control box.
