3. MIG Torch Adaptor (Euro Style)
The MIG Torch adaptor is the connection point for the MIG welding Torch. Connect the MIG Torch by pushing the
MIG Torch connector into the brass MIG Torch adaptor firmly and screwing the plastic MIG Torch nut clockwise
to secure in position. To remove the MIG Torch simply reverse these directions.
4. Remote Control Socket
The 8 pin Remote Control Socket is used to connect remote control devices to the 2RT Wirefeeder. To make con-
nections, align keyway, insert plug, and rotate threaded collar fully clockwise.

5. Local/Remote Switch (Located in wire feed compartment)
The remote / local switch(inside the 2RT) is used to switch between using the controls on the wire feeder and
using controls on a remote device attached to the wirefeeder (such as a MIG Gun with remote voltage and wire
feed speed control). To use the controls on the wirefeeder the switch must be in the Local position. When the lo-
cal/remote switch is in the local position, the 2 RT wirefeeder controls will take over and all voltage and wire feed
speed will be made from there. To use a remote control device (such as a MIG Gun with remote voltage and wire
feed speed control) the switch must be in the Remote position. Note that the MIG Gun trigger will operate at all
times regardless of the position of the local remote switch (i.e. in both local and remote modes).
