9. Remote Control Socket
The 8 pin Remote Control Socket is used to connect remote control devices to the welding power source.
To make connections, align keyway, insert plug, and rotate threaded collar fully clockwise.

Note that the remote local switch (item 19) located in the wirefeed compartment should be set to remote
for the amperage/voltage controls to be operative.
10. Multifunction Control - Voltage, Down Slope & Arc Force
The multifunction control knob is used to adjust Voltage (MIG Mode), Down slope (TIG Mode) and Arc
Force (STICK Mode) depending on the welding mode selected.
NOTE!
The preview functionality provided on this power source is intended to act as a guide only. Some differences may be
observed between preview values and actual welding values due to factors including the mode of welding, differences
in consumables/gas mixtures, individual welding techniques and the transfer mode of the welding arc (ie dip versus
spray transfer). Where exact settings are required (in the case of procedural work), it is recommended that alternate
measurement methods be utilised to ensure output values are accurate.
