Changing The Feed Rollers; Mig/Mag Welding; Adjustment Guidelines For The T.i.m.e. Process - Fronius T.I.M.E. SYNERGIC Bedienungsanleitung

- Shift the selector switch for digital indications
position
- Set a value of ~ 5 m/min on the welding power dial
Warning! During the wire-infeed operation, hold the welding
torch facing away from your body.
- Press the wire-inch button
the end of the torch
- To end the wire-infeed operation, release the wire-inch 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
- Shift the mains switch to the "O" position

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 to the "O" position
- Open the wire-spool cover
- 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.
- Push axles - back in again - the anti-twist lock of each axle must
latch into place
- Push the pressure levers
- Pivot the clamping devices
- Set the contact pressure by means of the clamping nuts
- Close the wire-spool cover
into the m/min
until the wire electrode protrudes out of
and forwards
and upwards
and downwards
and into the vertical position

MIG/MAG WELDING

Warning! Before starting up for the first time, read the sections
headed "Safety rules" and "Starting to use the power source".
- Plug the earth cable into the current socket and latch it in firmly.
- Connect the other end of the earth cable to the workpiece
- Plug the machine into the mains
- Switch the machine on at the mains switch
- Mains control lamp lights up
Warning! On water-cooled machines, the water-flow must be
checked at regular intervals while the machine is in operation -
you must be able to see that the coolant is flowing back properly.
- Pre-select the welding program with the program selector switch
('No Program' indicator must not light up or start flashing)
N.B.! All the programs were welded with a standard torch (apart from
T.I.M.E. programs). When standard programs are welded with a T.I.M.E.
torch, this may lead to changes in the welding properties.
- Shift the operating-mode switch
position
- Connect the remote-control unit to the remote-control socket
pulsed-arc welding, connect up the TR 34 T.I.M.E. remote-control
unit and set the operating-mode switch on the TR 34 T.I.M.E. to
'Pulsed-arc welding')
- Set the arc-length correction dial
- Set the droplet-detachment correction dial
- Set the required amperage on the welding power dial
value is shown on the amperage indicator)
- Open the gas-cylinder valve
- Set the gas-flow rate
- Press the torch trigger and start welding
N.B.! In some cases, it may be necessary to correct the gas pre-flow time
or gas post-flow time
ADJUSTMENT GUIDELINES FOR THE T.I.M.E.
PROCESS
Thanks to the single-dial operation of the T.I.M.E. Synergic, it is only
necessary to set the appropriate wirefeed speed ; the correct welding
voltage is then set automatically. Corrections are only then needed to the
arc length.
Calculating the deposition rate
This formula only holds good for a wire diameter of 1.2 mm and for
unalloyed and low-alloy steel wires. It takes no account of spattering
losses (typically 1 - 2 %).
Deposition rate [kg/h] =
e.g. wirefeed speed = 20m/min
Deposition rate [kg/h] =
