Abstract

PURPOSE:To obtain a titled device that can protect a lamp and save electric power by detecting a no-load voltage by the controlling circuit of a welding machine, opening a lamp circuit, detecting arc current and extinguishing the lamp by opening the lamp circuit during generation of arc. CONSTITUTION:In a manual welding machine 1 provided with an illuminating lamp L for in-board work and a built-in electric shock preventer, the low voltage lamp L is connected between a junction point A of a welding cable and a contact B of grounding side through a controlling circuit consisting of a protecting circuit alpha and a power saving circuit beta. During suspension of welding, a current is allowed to flow by low voltage of a transformer of the welding machine 1 from a point A to a point B through contacts CR1, WR1 and the lamp L, and the lamp is turned on for work. When the no-load voltage is applied between a welding rod 6 and a base metal at the time of starting welding, the contact WR1 is opened by the action of the protecting circuit alpha to protect the lamp L. When an arc is generated by the no-load voltage and the welding voltage is detected by a current detector CT, the contact CR1 is opened by the action of the power saving circuit beta, and the lamp L is extinguished during welding work.

Work lighting inside the ship includes work lights that are used by each worker, in addition to constant illumination lights that are appropriately placed. When using this work light, the work light was turned on by plugging the work light cable socket into outlet boxes pre-placed in various parts of the ship to provide work illumination.

Therefore, when performing welding work onboard a ship, workers must select an outlet box that fits the length of the work light cable as they move from one work position to another, and may also be required to select an outlet box within the length range of the work light cable. There were problems such as the lack of lighting.

Until now, it has been considered to use a welding cable to turn on the work light, but the welding machine is equipped with a general-purpose electric shock preventer as shown in Figure 1, and this electric shock preventer interrupts welding. Electric lights cannot be used because the voltage of the welding cable becomes 24V during operation.

That is, although the holding coil (1-IC) is always excited by applying a DC voltage, it does not operate because of the wide distance between it and the movable iron core. Further, during welding suspension, the current flowing through the starting coil (SC) is small, so the suction force is weak and it does not operate, and 24V is output between points A and B.

By touching the common connecting rod (α) to the workpiece (b), it is possible to short-circuit the secondary winding of the welding machine, and the starting coil (SC)
) increases, the movable core enters the suction range of the holding coil (HC), the main contact (1) closes, and at the same time the interlock contact (d) opens. Therefore,
No-load voltage 85 between points A and B until an arc occurs
V is being output.

When a no-load voltage of 85V is applied, the circuit relay (OR) is activated and interrupts the circuit of the holding coil (HC), but the electric charge stored in the electrolytic capacitor 0 is transferred to the holding coil (IT C').
The battery returns to its initial state after about 12 seconds due to the discharge. Therefore, 85V is first output between the two points A and B, and 24V is output after 1.2 seconds.

On the other hand, the no-load voltage is 85V! If an arc occurs between two points IIA and B, the arc voltage (

In this way, the voltage changes between points A and B depending on the operating state of the shock protector, so if 24V is used for the bulb of lamp ■, the filament of the bulb will burn out when no-load voltage is applied. Also, if a light bulb of 85V or higher is used, the voltage will be 24V and it will be dark during welding breaks when lighting is required.

The present invention has been made to solve these problems, and it is possible to turn on the work light by using the voltage when the welding machine is at rest (26V because the electric shock protector is activated).
