Welding control TE 90 is a microprocessor control for single-phase
resistance welding machines. The welding controller has the task of
To control machine elements, especially the SCR, which controls the adjustment
of the control the welding current. The duty cycle that the TE 90 performs is
described using the programming parameters.

– SCR synchronous control, welding time regulation by phase cut
– Simple programming via 4 keys
– Current rise and pulses
– Single point and automatic
– Secondary current compensation for welding
dirty metal sheets and wires
– Welding time lock optimizes current draw from the mains
– Solenoid valve 24 Vdc 7.2 W max. with output protected against short circuits

Air-operated, lube-free cylinder eliminates oil mist in the shop environment.
Electrode force is adjustable via integrated filter / regulator combination.
Reduce shop noise with integrated speed control valves, shock absorber for end of cylinder stroke, and air exhaust mufflers.
Two-stage electronic footswitch initiation (1st stage closes tips without welding, 2nd stage initiates weld schedule.)
Pre-wired to accept a second footswitch (Option 72977).
A second footswitch allows for immediate recall of a second weld time / current setting. This is helpful when different settings are required on the same workpiece.
PINCH POINT SAFETY OPTION: WSI-supplied TECNA Rocker Arm Welders are available with UNITROL Soft Touch Safety for pinch point protection.
