Description

Full automatic welding cutting torch handle

Technical field

The utility model relates to a kind of welding apparatus, specifically a kind of welding torch handle that is applied in the practices such as gas welding, cutting, heating.

Background technology

In the gas welding, the effect of welding torch mainly is that oxygen and combustion gas are mixed according to certain ratio, and can form heat and imitate high and size, shape are closed in the flame that requires, thereby can be carried out necessary processing to metal works; Present welding torch comes branch can be divided into two kinds according to forming structure: monoblock type and combined type, it is flexible more, convenient, widely applicable to compare combined type welding torch.

The sparking mode that the welding torch is commonly used has three kinds at present: manual firestone, electronic ignition type, quick igniter; The shortcoming of wherein preceding two kinds of sparking mode is to need igniting again when reworking, and readjusts gas mixture ratio; The advantage of igniter is that a faint normal open flame source is arranged all the time fast, when not working, the welding torch hung on the control crotch and can cut off source of the gas, need not to adjust gas when reworking, take off the preceding state flame of directly the close igniter burning things which may cause a fire disaster of burner can being realized having a rest from crotch, so just, can carry out continuous work, improve operating efficiency; But the maintenance of such situation just needs the mechanism of a fixing complexity and realizes and require certain installation configuration space.
