Connection at DC STICK welding
NOTE
•
When using the welding electrode holder, the specified connector needs to be attached to
the welding electrode holder side in the same way as the base metal side cable.
1.
Connect the power cable for base metal side to the output terminal (base metal side) and base metal.
●
At the welding power source side, fit the convex part of the connector and concave part of the output terminal for
secure connection and tighten them in the clockwise direction.
2.
Pass the cable (welding electrode holder side) through the grip of the specified connector.
●
The length of the conductor shall be about the same as the length of the sleeve.
3.
Attach the sleeve to the conductor of the cable.
4.
Insert the sleeve into the connector terminal, and fix the sleeve using a screw.
●
Tighten the screw at 12 N
・
m using a hexagonal wrench.
5.
Fit the grip onto the connector terminal.
6.
Connect the power cable for welding electrode holder side to the output terminal (torch side).
●
Connect the connectors as same as above.

Connection of shield gas
This section explains the procedure for connecting the shield gas. Refer also to the instruction manual of wire feeder.
CAUTION
•
In using the welding power source for DC STICK welding, prepare a welding electrode
holder by the customer.
•
After five seconds have passed, the safety voltage (approx.15 V) is automatically
provided.
