YJHB-2 High-energy precision repair welder Cold welding machine Thin-plate welding machine. YJHB-2 is a micro repair welder with TIG-like welding pulse.
The welder can generate very precise welding pulse to produce fine-sized and positioned welding spots. The machine can weld a variety of materials incl.All types of steel and iron, Aluminum, copper, brass, bronze. It can weld even very small details with very thin fillers, and weld fast with thicker fillers. Although the machine is easy to use, it still requires some manual dextetiry. We recommend you use some time to practice, with suppoct from the tips in this manual.
1:The machine can weld in Fe, Cu, Al. The machine can not be used for welding:Sn, Zn. 2:The machine can be used. Repair of worn and faulty details in the form tool for pressure casting, injection molding, blow molding, etc. Defects in castings, such as pinhole, sand holes etc.
Other small and precise welding tasks as a normal TIG welder can not perform. 3:Electric Input:220, V50HZ. 5:Maximum instant output is 40kw. Pulse power(current):1-99, Pulse time(hours):1-99. Set filler mode:Pulse power(current):1-99, Filler diameter of 0.1-1mm.
7:Pulsens frequency:1Hz (mode4), 2Hz (mode3), 3Hz (mode2), 5Hz (mode1). This machine can be stored in the capacitor energy in the form of instant release pulse tungsten arc between the electrode and the workpiece, a high temperature arc of the metal material and the workpiece and the rapid melting of the wire welded together, to achieve the purpose of welding characteristics of this approach.Welding are: a very short time, the heat is very small. The welder can be completed within a few tens of milliseconds wire and workpiece welding process, so the base of the workpiece, the heat less than the small material temperature solder, no annealing discoloration. Since the volume of each solder bath pulses is smaller than 2mm3, stress is formed is also smaller.
Although a lot of welding needs a puddle combined, but because of the dispersion of the solder joint stress direction, the workpiece by the concentrated stress is small, so small welding deformation of the workpiece. Why type YJHB-2 can be comparable to or exceed the cold welding laser welding?1 High weld strength: complete welding metallurgy, can mend milling, filing and other post-processing. 2 Patch High precision: round wire fill material can be used to repair, do not lose the original datum, less the excess solder, post-surgery easier. The minimum amount of repair 0.3mm (0.3mm diameter of fill material). 3 Patch speed: the fastest repair of up to 100mm3 / min (cold welding repair in the field, it is absolutely another Surprisingly fast speed). 4 substrates injury: small hot spots, will not cause deformation of the substrate annealing. 5 The power distribution reasonable: the use of microcomputer chip control, a variety of materials with different diameters can get the best power. 6 large voltage range: Use the power switch when the voltage changes fluctuate within the range of + 20%, the machine still guaranteed to work, and to maintain a stable output power. 7 facilitate electrical connection: with a quick header, can be easily connected to the installation. Another big piece is not afraid. 8 Move easy: the whole small, (380 150 200) mm3, light weight, the host only 9kg.
