Abstract
The utility model relates to an energy-saving electric welding machine, an electric welding transformer primary coil is switched on with a power source contactor, a control coil of the power source contactor is connected with an electric welding control button, the control button is arranged on electric welding pliers, the control button is switched on during welding, and the electric welding machine enters the working state, the power source of the electric welding machine is automatically cut off at welding intervals, no no-load current exists, and the electric energy is saved.
Description
A kind of electric welding machine of technical field.
The background technology electric welding machine is a kind of intermittent work equipment, when not welding unloaded power consumption still very big, waste electric energy, to reach 30% of total electricity consumption according to the loss of measuring and calculating no-load current.
The electric welding machine that summary of the invention the utility model provides has been eliminated no-load current, thereby reaches purpose of energy saving.
The purpose of this utility model is achieved in that welding transformer primary coil and power contactor connection, the control coil of power contactor is connected with the electric welding control button, control button is located on the electrode holders, button is connected during electric welding, electric welding machine enters duty, the welder power automatic disconnection at intermittence of welding.
Since adopt such scheme, power connection during electric welding, and power supply disconnects when not welding, and has eliminated no-load current, has saved electric energy.
Description of drawings is described further below in conjunction with accompanying drawing.
Accompanying drawing is the utility model circuit diagram.
In the circuit diagram: 1. master switch 2. safety boxs 3. control transformers 4. electric welding control buttons 5. power contactor coils 6. power contactors 7. welding transformers 8. electrode holders
After the master switch 1 of specific embodiment electric welding machine is connected, by safety box 2 and control transformer 3 voltage is become safe voltage, supply with electric welding control button 4, after control button 4 is connected, 5 work of power contactor coil, power contactor 6 adhesives, welding transformer 7 is started working, and electrode holders 8 just can carry out electric welding.For the ease of operation, electric welding control button 4 is installed on the electrode holders 8, and electric welding control button 4 changes in welding rod or the welding intermittently for often driving button, and power contactor 6 will disconnect welder power, and no-load current disappears.Because the electric welding machine intermittent work, no-load current waste electric energy is very big, and energy-saving effect is remarkable behind the no no-load current.For safety, the voltage on the electric welding control button 4 is safe voltage.Power contactor coil 5 and power contactor 6 are one.
Claims (1)
1, a kind of electric welding machine, the primary coil of welding transformer is connected with power contactor, it is characterized in that: the control coil of power contactor is connected with the electric welding control button.
