Abstract
The utility model relates to the technical field of welding and is mainly composed of a power transformer, a spark gap, an oscillating capacitor, an air-core transformer and a high frequency coupling capacitor. The utility model is connected in series in a low-voltage welding circuit of a welding machine. During electric welding, high frequency electric sparks can be remained in the gap of electric arc so that the air conducts the electric arc in the ionized state, and the arc striking and stabilizing functions can be achieved. If the electric current is regulated properly, workpieces with thin walls can be welded.
Description
The utility model relates to welding technology field.
Existing alternating current-direct current arc welding apparatus, gas shielded welding machine are welding rod, electrode and directly contact generation electric arc in back with weldment, and this mode is too fast to the loss of gas shield welding electrode; And AC ﹠ D. C. arc welding machine wants repeated stock welding rod and the workpiece could the starting the arc sometimes, easily makes workpiece shift and reduces welding efficiency; Arc-welding machine is when the welding thin plate, and electric current has been transferred big can combustion wear workpiece, and electric current has been turned easy bonding welding rod down and can't have been welded.
The purpose of this utility model provides a kind of device that electric welding machine is played striking, stabilising arc effect.
The utility model comprises power transformer, is connected in parallel on the secondary discharging gap of power transformer, air-core transformer successively, is in series with oscillating capacitor between discharging gap and air-core transformer, is associated with carrier coupling capacitor on air-core transformer one output line.
This version that the utility model adopts, can be when the power transformer secondary voltage makes the oscillating capacitor charging reach certain numerical value, make the discharging gap conducting, thereby form the oscillation circuit that air-core transformer and oscillating capacitor are formed, at this moment, at the secondary high frequency voltage that just induces of air-core transformer.This device serial connection in electric welding machine low-pressure welding loop, when welding, is just kept high-frequency spark in the arc gap, make it air in the conducting of ionized state pilot arc, thereby played striking, stabilising arc effect.
Accompanying drawing has provided embodiment of the present utility model, and this figure is a circuit diagram of the present utility model.
In the embodiment that accompanying drawing provides, the leading-out terminal of power transformer (1) is parallel with discharging gap (2) and air-core transformer (4) successively, in the loop that discharging gap (2) and air-core transformer (4) form, be in series with oscillating capacitor (3), on air-core transformer (4) one output lines, be associated with carrier coupling capacitor (5).
When the utility model uses, the input of power transformer (1) and the input of welder transformer are joined, the output of air-core transformer (4): a line connects electrode holder, and another connects electric welding machine, and the output line of carrier coupling capacitor (5) connects the electric welding machine ground wire.Like this, when electric welding machine is worked, keep high-frequency spark in the arc gap, make it air, thereby played the effect of striking, stabilising arc, thereby also can weld thin plate in the conducting of ionized state pilot arc.Simultaneously because the effect of coupling capacitor (5) in circuit when holding electrode holder, do not have picotement.
Claims (1)
- A kind of high-frequency spark generator, it is characterized in that it comprises power transformer (1), be connected in parallel on the secondary discharging gap (2) of power transformer (1), air-core transformer (4) successively, between discharging gap (2) and air-core transformer (4), be in series with oscillating capacitor (3), on air-core transformer one output line, be associated with carrier coupling capacitor (5).
