14.2 Procedure of External Resistance Calibration
To measure the external resistance value, move the manipulator so that the torch will be close
to the jig stand. Then, use the cable for resistor measurement to connect the torch tip end
and the jig stand where base metal to be welded is set, as shown in the following figure.
For the cable for measurement, use a conductor of 38 mm
possible), and securely connect the tip body at the torch end and the jig stand using a bolt or
vice.
Torch
Remove the nozzle and chip from
the torch and pull back the wire.

Connect in this order: torch cable → wire feeder
→ positive (+) side power cable → welder
Use a bolt M6 to connect the cable for
resistance measurement to the tip body.
