| description | A device for automatic reduction of idling voltage in welding sets. It constitutes a separate attachment, which consists of a thyristor disconnecting switch, connected in series into the positive branch of the welding circuit, and of circuits comprising resistors and circuit-breakers, which connect the positive and the negative branches. It is characterised in that the current sensor (CI) is introduced in series with the thyristor disconnecting switch (T) into the positive branch of the welding circuit. The sensor controls the circuit-breakers (W2) and (W3), which connect the positive and negative branches of the input circuit (I+), (I-), as well as the circuit-breaker (W1), connected to circuit-breaker (W3). The circuit-breaker (W1) is connected in series to resistor (R1) and connects the positive and negative branches of the output circuit (O+), (O-). The resistor (R2) is connected in parallel between the circuit-breaker (W2) and the positive branch of the welding circuit, between the thyristor disconnecting switch (T) and the output clamp (O+). The (R1) to (R2) resistance ratio is larger than three. |
