I、 Key features
1. Analog circuit instead of SMD Tech on our THC, PWM driving mode,
ensuring high reliability of THC.
2. Circuit-broken protection. On Auto Mode torch lift up automatically in the
situation of HF disconnected, open circuit, short circuit, avoid crashing the torch.
3. Full-closed design, waterproof, dustproof, shockproof.
4. It adopts a method of modularization design, which is convenient for
installation, commissioning and maintenance.
5. Professional circuit-protection design greatly strengthens ability of
anti-jamming. Resister and Capacitor Absorb Circuit is adopted on power
supply, preventing the interference of Surge Voltage and Harmonic Wave to THC
effectively. Pressure Sensitive Circuit protection is adopted, avoiding the damage
of over-voltage, and mis-connecting of power supply. Time-varying circuit is
adopted, avoiding the damage of over-high voltage brought by workpiece under
sensing (protection voltage>91v). Self-recovery circuit is adopted on
signal-collecting part, at this part, the detecting circuit would break off if the
current is over 1.3Ah.
6. Outside height setting, besides the HEIGHT button on operation panel, there's
a R39⊕ at the back of control box, adjusting the height when the set height is
not right.
