Tig Welding With High-Frequency Ignition (Hf) - Fronius MAGIC WAVE 2600 FUZZY Mode D'emploi

TIG WELDING WITH HIGH-FREQUENCY
IGNITION (HF)
Warning! At TIG welding, the manual electrode cable will
always be live when:
- the mains master switch
- the operating mode is in the
when the "start welding" signal has been given from the
torch trigger.
Warning! Make sure, when the manual electrode cable is not
in use, that it is either disconnected from the machine or else
fastened to the machine in such a way (insulated) that the
electrode holder and the coated electrode cannot touch any
electrically conductive or earthed parts.
Fig.23 MW 2600 / 2600CEL / 3000 or TT 2600 / 2600CEL / 3000 as a TIG
welding machine, consisting of: power source with control unit, cooling
unit, AW 42 manual torch, earth cable and gas cylinder with pressure
regulator (not illustrated).
START UP
- Fit the torch with a tungsten electrode and a gas nozzle
(see the instruction manual for the torch concerned).
- Plug the earth cable into the current socket
firmly.
- Connect the gas hose to the machine and the gas pressure
regulator.
- Plug in the mains plug.
- Switch on the mains master switch
- Shift selector button
LED or lights up.
- Pre-select the type of current with the current-type selector
switch (only on MW 2600 / 2600CEL / 3000)
- In AC~ mode: Set the balance and AC frequency
(only on MW 2600 / 2600CEL / 3000)
- If necessary, connect a remote control unit
- Select welding parameters (command value for main current I
is displayed on ammeter
- Open the gas cylinder valve by turning it anticlockwise.
- Press gas-test button

IGNITING THE ARC:
- Make sure the welding current is switched off. Place the
electrode on the weld at the point where the arc is to be ignited,
tilt the torch backwards until the edge of the gas nozzle is resting
on the workpiece, leaving a gap of between 2 and 3 mm
between the tip of the electrode and the workpiece. Fig. 24a
position and
- Close your visor.
- Switch on the welding current with the torch trigger
- Arc ignites without touching the workpiece. Fig. 24b
- Move the torch into the normal position. Fig. 24c
Advantage: no contamination of either the electrode or the work-
piece.
Important! After ignition in AC~ and DC, the high frequency
switches off automatically.
