WARNING
Follow the instructions below to avoid electric shock.
Do not touch the live electrified parts, as this will result in a fatal shock and sever burn.
⚫
Do not touch the live electrical parts of the welding machine.
⚫
Have a qualified electrical engineer ground the case of the welding power source and the
base metal or jig electrically connected, following a local law.
⚫
Disconnect the welding power source from input power supply by turning off the line
disconnect switch in the power box before grounding the welding power source or base
metal and connecting the cables or hoses.

⚫
Tighten and insulate the connections of cables.
⚫
Securely attach the cover of the welding machine after connection of the cables.
⚫
Do not expose the conductor parts of the wiring terminals for welding cables. Use the
auxiliary heat shrinkable tubes (or high temperature insulating tapes) for good insulation.
8.1 Connection at the Output Side of the Welding Power Source
CAUTION
In order to prevent occurrence of electromagnetic harm, refer to the following
items when connecting the welding cables. In case of electromagnetic harm,
refer to the following items again.
⚫
Reduce the length of the welding cables as much as possible.
⚫
Keep the welding cables close to the ground as much as possible.
⚫
Make the cable at the workpiece side parallel to the cable at the wire feeder side.
⚫
The grounding of the workpiece and welder shall not be shared by other.
