The invention relates to an inverter electric welding machine device with adjustable electric arc, which comprises a welding host machine, a welding torch, a liquid cooling system, a compressed air supply device, a protective gas supply device and an electric arc adjusting device, wherein the welding torch comprises a handle, a main cylinder body, a nozzle, an outer bushing, an inner bushing, a compression screw, a tungsten stick, a ceramic sleeve and a fixed sleeve. An electric arc adjusting device comprises an electric adjusting mechanism, and a control circuit of the electric arc adjusting device mainly consists of a push-and-pull coil and a reversing switch; the direction of current can be changed by switching the reversing switch, namely, the magnetic induction polarity of the push-and-pull coil can be changed, so that the moving direction of an induction magnet coil is forced to be changed, and the inner and the outer bushings of the welding torch are driven to change the moving direction of the tungsten stick; and a manual adjusting mechanism consists of an adjusting disc and a rotating sleeve, wherein the adjusting disc is manually rotated to drive the rotating sleeve to rotate, and the inner and the outer bushings moves up and down to drive the tungsten stick to move by mechanical transmission. The inverter electric welding machine device has the advantages that one welding machine can realize two electric arc types; free electric arc continuous compression can be converted into plasma electric arc; and the structure is simple, and the use is convenient.

The invention discloses a soft skeletal muscle driver based on a ferrofluid and an electromagnetic coil. Artificial skeletal muscle (I) is a cylindrical or semi-cylindrical shape, the interior of themuscle is in a grid hollow pipe design, and an artificial elastic fiber material is adopted; the ferrofluid (II) fills in the grid hollow pipe and can flow freely; the electromagnetic coil (III) is distributed on the surface of the artificial skeletal muscle (I), a flexible copper coil material is adopted, and the coil deforms and bends along with the artificial skeletal muscle (I); and the electromagnetic coil (III) is powered on and an magnetic field is generated, the ferrofluid (II) is promoted to be gathered in the different positions in the artificial skeletal muscle (I), the inner pressure is generated, bending and deformation of the artificial skeletal muscle (I) is achieved, and driving of soft skeletal muscle is achieved. Compared with current popular pneumatic artificial skeletalmuscle, the driver has the advantages of being high in controllability, light and convenient and no need of an extra pneumatic device.

The invention relates to the technical field of electromagnetism, in particular to electromagnetic adjusting equipment and a using method thereof. The electromagnetic adjusting equipment comprises an insulating shell, electromagnetic assemblies, an energy supply assembly and working assemblies, wherein the energy supply assembly is fixedly arranged at the center of the upper surface of the insulating shell, the multiple electromagnetic assemblies are arranged at the edges of the upper surfaces of the two sides of the energy supply assembly, and the working assemblies are arranged in the electromagnetic assemblies; and each electromagnetic assembly comprises a protection column, an electromagnetic coil and a supporting block, the protection column is fixedly arranged on the upper surface of the supporting block, and the electromagnetic coil is wound on the side surface of the protection column. The electromagnetic adjusting equipment has the beneficial effects that power is supplied to a first electromagnetic column and a second electromagnetic column through a power supply, so that the first electromagnetic column and the second electromagnetic column are magnetized, and a bearing can rotate due to the effect of a magnetic field; since an outer ring of the bearing is fixed on the inner surface of the supporting block, an inner ring rotates and drives the first electromagnetic column and the second electromagnetic column to rotate to generate a magnetic field, and then the magnetic field is expanded under the action of the electromagnetic coil.
