In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be implemented in other ways different from the specific details set forth herein, and one skilled in the art may similarly generalize the present invention without departing from the spirit of the present invention, and therefore the present invention is not limited to the specific embodiments disclosed below.

Furthermore, the references herein to "one embodiment" or "an embodiment" refer to a particular feature, structure, or characteristic that may be included in at least one implementation of the invention. The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments.

Example 1:

referring to fig. 1-2, the adjustable welding gun of the present invention includes a welding assembly 100, where the welding assembly 100 includes a heating element 101 and a gun head 102, and the gun head 102 is provided with an installation cavity; and an adjustment assembly 200, the adjustment assembly 200 being disposed on the welding assembly 100, a first connector 300, the first connector 300 being disposed on the adjustment assembly.

Specifically, the welding assembly 100 serves as a torch body for performing welding work. In the present embodiment, the torch is plasma arc welding, which is a fusion welding method using a high energy density beam of plasma arc as a welding heat source. The plasma arc welding has the characteristics of energy concentration, high production rate, high welding speed, small stress deformation, stable arc, suitability for welding thin plates and box materials and the like, and is particularly suitable for welding various refractory metal materials (such as tungsten, molybdenum, copper, nickel, titanium and the like) which are easy to oxidize and have strong thermal sensitivity.

The gas is heated by electric arc to be dissociated, and is compressed when passing through the water-cooling nozzle at high speed, so that the energy density and the dissociation degree are increased, and plasma arc is formed. Its stability, heat productivity and temp. are higher than those of general electric arc, so that it has higher penetration force and welding speed. The gas forming the plasma arc and the shielding gas surrounding it are generally pure argon. Depending on the material properties of various workpieces, helium, nitrogen, argon, or a mixed gas in which two gases are mixed is also used.

The welding assembly 100 is provided with a heating element 101, the heating element 101 comprises a transfer arc wire 101a and a non-transfer arc wire 101b, the transfer arc wire 101a is connected with the negative pole of the power supply, and the non-transfer arc wire 101b is connected with the positive pole of the power supply.

Plasma arcs have two modes of operation. One is "" non-transferred arc "", the arc burns between the tungsten electrode and the nozzle, primarily for plasma spraying or heating of non-conductive materials; at this time, the tungsten electrode is connected to the negative terminal of the power supply, the nozzle is connected to the positive terminal of the power supply, and a plasma arc body is generated between the tungsten electrode and the nozzle. The other is "" transferred arc "", after the arc is ignited by the auxiliary electrode at high frequency, the arc is burned between the tungsten electrode and the workpiece for welding; at the moment, the tungsten electrode is connected with the negative current terminal, the weldment is connected with the positive current terminal, and the plasma arc is generated between the tungsten electrode and the weldment. Metal welding and cutting almost all employ a transfer type plasma arc because the transfer arc transfers more heat to the weldment. The weld is formed in two ways, namely a penetration type and a perforation type. The plasma arc in the former form only penetrates through the base metal to form a welding pool, and is mostly used for welding plates with the thickness of 0.8-3 mm; the plasma arc in the latter form only melts through the plate to form a keyhole-shaped molten pool, and is mainly used for welding plates with the thickness of 3-12 mm. In addition, the micro-plasma arc welding with small current is especially suitable for welding thin plates of 0.02 to 1.5 mm.

Plasma arc welding is a high quality welding process. The depth/width ratio of the welding seam is large, the heat affected zone is narrow, the deformation of the workpiece is small, and the types of weldable materials are various. Especially the development of the plasma arc welding of the pulse current and the plasma arc welding of the consumable electrode, and the application range of the plasma arc welding is enlarged. The lance tip 102 is provided with a mounting cavity for placing solder.

In this embodiment, the outer wall of the welding assembly 100 is provided with a protective jacket to prevent the welding operator from being scalded. In this embodiment, the end of the welding assembly 100 shield is configured as a removable structure having a protective cover 100a, the protective cover 100a is threadably attached to the welding assembly 100 body, and the end of the welding assembly 100 where the protective cover 100a is located is the power input and the gas input end. Therefore, the protective cover 100a is a detachable structure, which facilitates the input pipeline arrangement and the input pipeline detachment for replacing the welding gun.
