SECTION 4 — OPERATION
4.2 Operation
4.2.1 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 connec-
tions.
• 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 ma-
chine (see Technical Data)
4.2.2 MMA Welding with remote control
• Select welding polarity as in paragraph 4.3.1.
• 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 weld-
ing electrode being used. (The standard New-Arc 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.
4.2.3 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.
4.2.4 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.
