COOLING UNIT
WCU1kW_C
P 1L/min = 1000W
Capacity = 5 L
U1 = 400V +/- 15%
The cooling unit is working on 400V +/-15%.
The cooling unit is automatically detected by the machine. In the menu
,
the cooling unit can be disabled in TIG mode.
Make sure that the cooling unit is turned off before disconnecting the inlet and outlet hoses for torch liquid.
The coolant is harmful and irritates the eyes, the mucous membranes and the skin. Hot liquid may cause burns.
LOCK MODE
The LOCK feature will disable the knobs and keypad to prevent accidental changes in the settings. Pressing and holding the button
for 3
seconds (Fig 2 - 8) activates and displays
, the machine is then locked.
The buttons are not active, use the scrollwheel to adjust the current value previously set by a percentage related to the tolerance setting
.
To unlock the commands, press the
button for 3 seconds, the display shows
, then goes back to current display.
CALIBRATION
This mode is dedicated to the calibration of the welding accessories such as the torch, earth clamp and earth cable.
The calibration is designed to compensate variables such as the length of the accessories in order to adjust the measurement of the voltage and
improves the calculation of the energy.
Use the menu
to access the calibration.
The first step
requires short-circuiting the accessories. It is recommended in TIG to create the short-circuit between the torch
nozzle support and the earth clamp or directly on the metal being welded on. Once the short-circuit is created, validate using the scroll-wheel.
The second step starts, a bar of progress
is shown on the MMI display of the machine. Press the button on the torch to start the
circulation of the current for the calibration.
If the operation is successful, the machine leaves the mode directly and display the resistance value of the accessories shortly. This value is now
taken into account when displaying the voltage and calculating the energy.
Otherwise, the machine leaves the menu directly with a long display of
. If the operation fails, the circuit was not done correctly
and the calibration must be redone.
DISPLAY CURRENT/VOLTAGE DURING WELDING
During welding, the machine measures and displays the welding current and voltage.
After the weld, the average current and voltage values or the energy and duration of the welding bead are displayed until the interface (buttons or
scrollwheel) are touched or if the weld resumes.
Access to current / voltage or energy / duration configuration is available through the menu
.
ENERGY MODE
This mode is designed for welding with energy control framed by a DMOS and allows, as well as displaying weld bead energy information, to set :
- The thermal coefficient
in line with the standard used : 1 for standard ASME and 0.6 (TIG) or 0.8 (MMA) for the European standard. The
energy displayed is calculated taking this coefficient into account.
- The length of the weld bead
(OFF - mm) : if a length is stored, then the energy is not shown in joule but in joule / mm (the unit displayed
«J» flashes).
