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.
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.
