Warning! The coolant circulation must be checked at
regular intervals while the machine is in operation - it
must be possible to see that the return-flow to the
reservoir is working correctly.
If the coolant pump is running but is not making the coolant
circulate, the water forward-flow circuit must be vented, as
follows:
- Mains switch
into the "I" position - coolant pump starts
running
- Pull back the snap ring on the plug-type connection for water
forward flow and unplug the water forward-flow hose
- Using a wooden or plastic pin, carefully push in the conical
nipple in the middle of the plug-type connection for water
forward flow and release it again when water starts to seep
out
- Plug the water forward-flow hose back in
- Check that the water connections are watertight
- Repeat this procedure as often as necessary until you can
see that coolant is flowing back properly
Setting the shielding-gas rate
- Plug in the mains plug
- Shift the mains switch
- Press the "Gas test" button
- Turn the adjusting-screw on the underside of the pressure
regulator until the manometer indicates the desired flow-rate
Mounting the wire spool
- Shift the mains switch
- Open the wire-spool cover (DS III) or the left side panel of the
TotalArc² 3000 power source
- Take off the side panel from the power source
- Mount the wire spool onto the spool holder
round
- Latch the locking bolt into the opening provided on the body
of the spool
- Adjust the braking force with the clamping screw
- Replace the wire-spool cover or side panel
N.B.! The brake should always be adjusted so that the wire
does not continue unreeling after the end of welding - but
without overtightening the clamping screw, as this would cause
motor overload.
Warning! Make sure that the wire-spool is sitting firmly
on the spool holder.
Feeding in the wire electrode
- Shift the mains switch
- Open the wire-spool cover (DS III) or the left side panel of the
TotalArc² 3000 power source
- Remove the left side panel of the power source
- Pivot the clamping devices
- Pull the pressure levers
- Insert the wire electrode though the infeed tube
roller drive and around 5 cm into the infeed tube of the
welding torch
- Push the pressure levers
- Pivot the clamping devices
- Set the contact pressure by means of the clamping nuts
and
into the "I" position
into the "O" position
- the right way
into the "O" position
and
forwards
and
upwards
of the 4-
and
downwards
and
into the vertical position
N.B.! Set a contact pressure that is high enough to ensure
smooth wire feed, but not so high that the wire electrode is
deformed.
- Arrange the hosepack in as straight a line as possible
- Detach the gas nozzle from the torch
- Unscrew the contact tube
- Plug in the mains plug
- Shift the mains switch
Warning! During the wire-infeed operation, hold the
welding torch facing away from your body.
- Press the wire-inching button
protrudes out of the end of the torch
- To end the wire-infeed operation, release the wire-inching
button
N.B.! The wire spool must not continue to unreel after you
release the torch trigger. Re-adjust the brake if necessary.
- Screw in the contact tube
- Fit the gas nozzle
- Close the wire-spool cover or side panel
- Shift the mains switch

Changing the feed rollers
In order to achieve satisfactory wire travel, the feed rollers must
be suitable for the diameter and alloy of the wire to be welded.
- Shift the mains switch
- Open the wire-spool cover (DS III) or the left side panel of the
TotalArc² 3000 power source
- Remove the left side panel of the power source
- Pivot the clamping devices
- Pull the pressure levers
- Pull out axles
-
- Remove feed rollers
- Insert new feed rollers
N.B.! Insert the feed rollers in such a way that you can still see
and read the designation for the wire diameter.
