Welding wire inching
Press the “INCHING” (8) button on the operation panel
to feed the wire manually. The wire is fed forward while
this button is pressed. And the lamp is on while feeding
the wire.
* Inching is available when the welder is in standby state.
* Current set value for the main welding is used to
determine the wire inching speed.
* If this button is pressed when the “F. ADJ” or
“RECORD” (“FUNCTION” (12)”) is selected, the “no”
“Arc” are displayed on (2) and (5) respectively to
indicate that it is not possible to feed wire.

CAUTION
Wire extends out from the end of the welding torch and may stick into the
eye, face or body, which can cause injury.
Do not perform wire inching operation or pull the torch switch with your eyes, face or body close to
the end of the welding torch. Wire may stick into your eye, face or body.
CAUTION
Applying high-speed wire inching with the torch cable bent may cause the
wire to run through the resin liner and the cable.
In case of using a torch cable with the resin liner, straighten the torch cable and reduce the feed amount (current) to
a half or less before performing the wire inching. Please replace any damaged liner or cable with a new one as use
of them may cause gas leak or insulation deterioration.
Attention
In case of using a welding wire with a small diameter (0.8 mm
2
or 0.9 mm
2
)
Use of a wire in small diameter may cause unstable wire feeding. In case of using such wires, please feed the
wire at low speed or contact Panasonic representatives.
CAUTION
Prior to checking, read the operating instructions of the applied gas
regulator.
Make sure to read and understand safety precautions.
