TE 470

MAIN FEATURES

• Simplified programming by means of 5 push-buttons and LCD alphanumeric display.
• Controlled-diodes synchronous drive with phase shift control for welding current adjustment.
• 63 welding programs to be stored up; 2 programs can be recalled from the handle.
• 19 programmable parameters or more for each program.
• Slope and pulse functions; pre-weld and post-weld functions.
• Welding times adjustment in half-periods.
• Display of both welding current in kA, and connected conduction angle.
• Working modes: FIX, PW%,IK, ENERGY.
• Either welding current or conductor angle limits.
• Automatic double stroke function (to be employed only when the welder has been designed for this function).
• Three working modes along the machines stroke: SHORT, LONG, AUTO.
• Stepper function to balance the electrodes wear-out with adjustable curve.
• Welds counter.
• Programming key-lock.
• Single and automatic cycle. WELD/NO WELD function.
• Delay of first phase shift adjustment to get the bet balance of the machine absorption from the mains.
• Control of 2 solenoid valves 24 Vdc 7,2 W Max with protected output against short circuit: electrodes closing valves and double stroke valve.
• Self-adjustment to the mains frequency 50/60 Hz.
• Data communication with field bus (RS232, RS485)
• Minimal I/O for interfacing with plcs and safety systems.
• Calculation and check-up of the thermal current with alarm signal.
