MMA Welding
• For straight polarity welding, connect the electrode holder to the positive weld terminal and the
earth return lead to the negative weld terminal. For reverse polarity welding, reverse these connections.
• Turn the mains switch to the on position, the digital will light and after a 4 second delay the machine
is ready to weld.
• Adjust the current control to the recommended setting for the size and type of welding electrode to
be used.
• Adjust the Arc Force control to your personal preference for the size and type of welding electrode
to be used.
• The R4000/R5000 is suitable for welding all types of electrodes within the current rating of the machine
(see Technical Data)
MMA Welding with remote control
• Select welding polarity.
• Plug the control cable supplied with the remote control into the remote control socket on the front of
the R4000/R5000
• Plug the remote control onto the other end of the control cable.
• Adjust the current control on the remote to the recommended setting for the type and size of welding
electrode being used. (The standard Newarc RC300 remote does not have current settings but is
marked 1 to 10, for the R4000 allow 40A per division and for the R5000 allow 50A per division).
• Turn the mains switch to the on position, the machine is ready to weld.
TIG Welding with TIG unit
• Connect the TIG unit to the R4000/R5000 and the shielding gas supply as per the diagrams in the TIG
unit manual.
• Select welding mode and current by adjusting the controls on the TIG unit with reference to the TIG
unit manual.
• Turn the mains switch on the R4000/R5000 to the on position, the digital displays on the R4000/R5000
and the TIG unit will light up, you are now ready to weld.
MIG Welding with Wire Feed unit
• Connect the WFU to the R4000/R5000 and the shielding gas supply as per the diagrams in the WFU
unit manual.
• Select welding mode and current by adjusting the controls on the WFU with reference to the WFU
manual.
• Turn the mains switch on the R4000/R5000 to the on position and select MIG on the mode switch, (this
will be automatic if a remote connection is being used). The digital displays on the R4000/R5000 and
the WFU will now light up, you are now ready to weld.
