Operation - NewArc R7000 Operational Manual

3. Operation

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 R7000 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 R7000.
• Turn the mains switch to the on position, the machine is ready to weld.
• 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. (Standard Newarc RC300 remote does not have current settings but is marked 1 to 10)
Arc-air gouging/cutting
• Connect Arc-air torch to the positive weld terminal (DCEP) and the earth return lead to the negative weld
terminal.
• Connect a hose suitable for use with compressed air up to a pressure of 10 bar (150 psi) between the air
compressor (or air output connector) and the connection on the Arc-air gouging torch.
• Turn the mains switch to the on position, upon switching on, the display will read "7000" and the
machines output will be inhibited, after 4 seconds the display will clear and the machine is ready to
be used.
• Turn the current control to the recommended setting for the size and type of carbon to be used.
• Most Arc-air torches have a button on the handle that needs to be pressed to facilitate the air flow, press this
just before commencing operations.
TIG Welding with TIG Unit
IMPORTANT!
Do not use the TIG unit until you have read and fully understood the TIG unit manual.
• Connect the TIG unit to the R7000 and the shielding gas supply as the diagrams in the TIG unit manual.
• Turn the mains switch on the R7000 to the on position, the digital displays on the R7000 and the TIG unit will
light up, you are now ready to weld.
• Select welding mode and current by adjusting the controls on the TIG unit with reference to the manual.
