3. WELDING CONTROLLER CS-08
This controller satisfies the best exigencies in welding control. It is
designed for a good control of welding current through the use of a feedback
loop. It is built with a keyboard integrated in the front panel.
Main features
Storage of 60 different welding programs.
Programming by 16 buttons.
LCD Display allows displaying programmable parameters, true RMS welding
current with accuracy and other messages in process.
Built in ammeter with 5 Led 7-segment Display, showing for each
spot the welding time in cycles and the true RMS welding current in kA. The
ammeter can monitor the welding current and can display the current of each
half cycle of the weld on LCD. On each weld spot the ammeter can perform
self-calibration in order to provide high accuracy for the measured current.
The welding current is measured using a toroidal coil placed in the
secondary circuit. 
Toroidal coil placed in the secondary circuit
Constant current operation. The operator directly presets the value
in kA of the desired welding current. CS-08 keeps the preset value, checking
for each cycle and modifying the welding current if necessary.
Stepper function compensates for variations of the welding quality due to
the electrodes wear. Welding current will be gradually increased according
to electrodes diameter enlargement.
2 solenoid (optionally 4) valve 24Vdc 7.2W for pneumatic circuit.
A welding diagram for spot and projection welding.
Counter for executed spot.
Optionally RS 485 allows connecting with a computer for programming and
other functions.
On demand it can be build with up to 4 additional inputs.
Direct drives thiristors up to 700A.
