4.03 REMOTE 17-Pin Connections
The REMOTE 17-Pin receptacle provides a junction point for connecting
various remote controls to the welding power source. The functions
available from this receptacle are:
•
Remote MIG synergic and Manual MIG Pulsers
•
Remote Control
•
Weld current and voltage signals for remote metering
To make connections, align keyway, insert plug, and rotate threaded collar
fully clockwise. The socket information is included in the event the
supplied cord is not suitable and it is necessary to wire a plug or cord to
interface with the REMOTE 17-Pin receptacle.
