WELDING CONTROL UNIT

TE700 MICROPROCESSOR WELDING CONTROL UNIT

The TE700 is a very versatile Tecna welding control unit as it may be adjusted to different types of welders; in addition to the spot welders and the projections welders, it can also be installed on roller welders.
Moreover, it may work with constant current regulation, fix, constant power, constant voltage and constant energy adjustement and in dynamic mode.
The number of inlets and outlets may be increased to better adjust the welding control unit to automatic machines.
The control unit is able to manage up to a maximum of 4 different welding transformers.
It is possible to store up to 300 different welding programs.
Each program may be identified by an alphanumeric identification so to easily track it down.
Each program consists of several programmable parameters that describes the working cycle.
In addition to the plain 4-stage welding cycle, the control unit allows the running of welding processes with pre-welding current, post-welding current, slope and pulses.
MAIN TECHNICAL FEATURES
Simplified programming via 6 keys and a backlit alphanumeric LCD.
Inverter command with IGBT at medium, allowing choosing the inverter working frequency between 1000Hz and 4000Hz.
Storage of 300 welding programs.
Each welding program may be given an 8-character alphanumeric identification.
Possibility of managing up to a maximum of 4 different welding transformers or up to a maximum of 4 different electrodes typologies through the same control unit.
Thermal protection for the welding transformer.
Up to 32 programmable parameters for each program.
Slope, pulses, pre-weld, post-weld functions and adjustment of the welding times with 1 ms resolution.
Display of the RMS welding current, energy, power, RMS electrodes voltage, original and final resistance, machine thermal use percentage measurements and, optionally, of the original thickness of the welded material and of the indentation at the end of the welding process.
6 operating modes: FIX, constant current, constant power, constant voltage, constant energy, DYNAMIC mode.
Limits relevant to: the welding current, electrodes voltage, energy, power, inverter use percentage, original and final resistance of the material to be welded; limit on the thickness and on the material indentation (optional).
Double stroke function Stepper function to compensate the electrodes wear with programmable curves.
Possibility of independently intervening on welding time and current through differentiated stepper laws.
Possibility of using 4 different stepper laws associated to 4 different spot counters which may be freely associated to each welding program.
