3.1 Setpoint Value Display (after switching on the device)

Main switch (3) ON

• After switching on the device, the Overview (Fig. 1) appears on the display (5).

• If <80°C appears on the display (5), the welding nozzle (9) will have cooled down.

• The heating and drive are switched off in this menu.

• The user can use the controls (4) here to perform all settings which are described in

the following chapters.

• However, if the heating element temperature is greater than 80°C when switching on,

the display will immediately change to Cool Down mode (Chapter 3.8 Cooling Down) in

which the blower is always operated at full power and hence the welding nozzle (8) is

cooled down.

• It is possible to change back to Work mode from this mode at any time, however.

• If the heating element temperature reaches 60°C, the blower will continue to operate

for about 2 min. and then switch off automatically again. The display (5) changes back

to the setpoint value display (Fig. 1).

• Pressing the e-Drive starts the heating and blower (if they are still switched off) and

the display changes to a mode described in Chapter 3.2 Work Display (Fig. 2).

• In addition, turning the e-Drive to Profile allows the carious welding profiles to be

selected (Chapter 3.7 Selecting Profiles, Fig. 3).

3.2 Work Display

• The heating and blower are active in Work mode.

• The drive starts after the wedge has been moved into the welding

position or if the drive is manually switched on via the Drive menu

(Chapter 3.3 Setting the Drive Speed).

• If no button is pressed for a definite period of time (welding

nozzle (9) NOT in welding position), the Standby menu

(Chapter 3.9 Standby) will be called up.

• If the mains voltage is outside (-13% / +15%) the specified nominal

voltage (230V or 400V), this is displayed with the symbol

and the measured undervoltage /overvoltage.

• The VARIMAT V2 continues the work.

• Depending on the undervoltage/overvoltage, the welding result can

be affected.

If the blower power is less than 100%, the set blower power

changes with the symbol.

• If the welding nozzle (9) is heating up, this is displayed on the display with the progress bar, arrow (up) and

actual value of the temperature (flashing).

• If the welding down (9) is cooling down, this is shown on the display with full progress bar, arrow (down)

and flashing actual value of the temperature.

• If the welding nozzle is not swivelled in, the menu Cool Down (Chapter 3.8 Cooling Down) and Profiles

(Chapter 3.7 Selecting Profiles) can be selected via the e-Drive controls (4). If the welding nozzle (9) is

swivelled in, the two menu items disappear and can therefore no longer be selected.

3. Work Mode

3.3 Setting the Drive Speed

•

The Drive key can be used to adjust the welding speed or the drive speed. This can be

set by turning the e-Drive in 0.1m/min. increments from 0.7m/min. – 12.0m/min. This

setting can be carried out with the drive switched on or switched off.

• If the welding nozzle (9) is not in the welding position, the symbol will

appear at the lower left edge of the displays (5).

• The drive can be switched on by pressing the e-Drive and the symbol will

appear. The speed can be set by turning the e-Drive .

• Pressing the e-Drive again executes the Stop command, which switches off the drive. The Setpoint

Value display or Cool Down appears on the display.

• If no entry is made by the controls (4) within 3 seconds, the new drive speed will be accepted. The

Setpoint Value display or Cool Down appears on the display (5).

• If the Drive key is pressed for 3 seconds, the display will change to another menu (see Chapter 3.6

Length Measurement, Service / Blower and Drive Counter). You can change to the relevant menu from

this menu by pressing the Heating key or Blower key .

Stop

3.4 Setting the Welding Temperature

• The heating temperature can be changed with the Heating key . The temperature

can be set in 10°C increments from 100°C – 620°C by turning the e-Drive .

The

setting is accepted after 3 seconds, as long as no button is pressed within these

3 seconds.

• The Cool Down menu (Chapter 3.8 Cooling Down) can also be selected here.

• Pressing the Heating key for 3 seconds changes the display (5) to Work mode. The

mains voltage appears below the drive speed. This call is only possible from the Work

display Chapter 3.2. A call from the Setpoint Value display or from the Cool Down

display is not possible.

• In case of a set temperature of 500°C and higher, the blower power is automatically

adjusted, if necessary. The adjustment only occurs if the set blower power is higher than

the suggested value. This adjustment is necessary in order to be able to reach higher

temperatures (> 500°C). However, the user can adjust the blower power to any value via

the Blower key (see Chapter 3.5, Setting the Blower Power).

You can change to the relevant menu from this menu by pressing the Drive key or

Blower key .
