Purchase AC spot welder to pay attention to the following points.
1. To determine the welding parts for light metal, generally choose AC spot welder.
Since the AC spot welder uses AC discharge welding, it is especially suitable for materials with high resistance. At the same time, the AC spot welder can use pulse, multi-pulse signal, circumferential wave, time, voltage, current and program control measures to weld the workpiece for point shooting, double point continuous, automatic control and manual control welding. It is suitable for welding tungsten, molybdenum, iron, nickel, stainless steel and other metal pieces, rods and wires.
2. AC spot welding machine welding discharge time is generally the shortest 1/2 circumferential wave that is 0.01 seconds, not suitable for some unique alloy products of high standard welding.
Determine the material of the welded parts is rare metal, generally choose the energy storage spot welder. As the energy storage spot welder adopts energy storage capacitor discharge welding, it has a small impact on the power grid, concentrated welding current, fast release speed, strong penetration and small heat affected area.
3. To determine the material of the welded workpiece is phosphor bronze tape, AC brazing machine should be selected from manganese copper or copper braided wire.
AC brazing machine belongs to a small category of AC spot welding machine, so brazing machine also choose AC discharge welding, using welding transformer temporary loading rate, equipped with graphite (tungsten) electrode, produce high resistance heat zone, while using pulse, multi-pulse signal, circumferential wave, time, voltage, current, program control measures, point, double point continuous, automatic control, manual control welding.
4. On the wire material, rod connection welding should be used butt welder, butt welder is divided into two-level butt welder and three-level butt welder.
Metal halide lamps with metal wire connection welding machine also known as hard material cook guide wire machine. Energy-saving lamps, fluorescent lamps, general fluorescent lamps and other metal wire connection welding machine is also known as soft material cook guide wire machine.
5. The cap sealing machine is generally used for workpieces that need to be packed and welded. The cap sealing machine is fed and discharged by hand, and the machine automatically completes the detection of the welding workpiece, which belongs to a series of actions such as seven chords, sealing, vacuuming, nitrogen filling, welding and resetting.
