The Remote Hand Controls is equipped with a twenty foot (6 m) interconnecting multi-conductor cord (unless otherwise specified) which enables the Remote Hand Control to be remotely located from the welding power

source or welding generator. The Remote Hand Control can be wall mounted or placed on a stand at the work area.

If it is necessary to install a muti-conductor cord of long- er length, refer to Table 2-1 for cord conductor size ac- cording to the desired length. Refer to Section 5 - Elec- trical Diagrams for connections

2-2. INTERCONNECTIONS

1.To make connections on models equipped with the twistlock plug, fully insert the twistlock plug that is attached to the Remote Hand Control cord into Remote Amperage or Voltage Control Re- ceptacle on the welding power source or welding generator. Turn the cap in a clockwise direction, as far as it will turn, to lock the connection.

2.To make connections on models equipped with the 14-pin or 5-pin Amphenol plug, align keyway, insert plug, and rotate threaded collar fully clock- wise.
