8. CONNECTION PROCEDURE AND GROUND FOR SAFETY USE
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.

Do not use a cable with lack of capacity or a seriously damaged cable.

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 Input voltage selection
The input voltage of this welding power source can be switched between 415V and 380V. It is set as
415V upon ex-factory. If the voltage of your local utility power is 380V, follow the instructions below to
switch the input voltage from 415V to 380V.
(1) Turn off the NF switch of the welding power
source and all of the line-disconnect switches.
(2) Remove the top cover of the welding power
source and find printed circuit board P30161X.
(3) Confirm that connector CN8 is connected to wires,
and connector CN7 is open circuited on P30161X.
This is the connection for 415V input voltage.
(4) Exchange the connectors of CN7 and CN8 to
open circuit CN7and link to CN8. This connection
is for 380V input voltage.
