Industrial Pedestal AC Resistance Spot Welder

Product Details

The AC resistance spot welder is a machine that can weld the workpieces firmly. The AC spot welder is composed of a step-down transformer, a current regulator, a heat dissipation system, welding wires, handles and other accessories. There is no need to take an electric welding rod when welding, just fix the two workpieces to be welded as the two electrodes of the circuit, and have the high temperature generated at the contact resistance to instantly melt the metal, thereby firmly welding the workpieces together.

★ Stable body structure
★ The secondary conductive part adopts the upper insulation method, which can avoid the short-circuit accident of the insulated part when the iron filings are assisted or the lower seat is installed and welded.
★ The upper and lower electrodes adopt the artificial tooth method with auxiliary stroke, which improves the operability and versatility during welding.
★ The speed of the pressurizing electrode can be adjusted arbitrarily, which reduces the impact of pressurizing the object to be welded and also reduces the noise during welding.
★ The transformer is designed with low impedance, and high-quality conductive materials are used on the secondary circuit, which reduces the internal loss and obtains a small input to obtain a larger welding current.
★ 15 welding procedures can be stored: different welding specifications can be stored in different welding procedures, which is very convenient and smooth to realize accurate welding of different workpieces.
★ The operation interface adopts digital tube or liquid crystal display, which is clear, clear and intuitive.
★ It is widely applied in iron wire hardware, household appliances manufacturing, sheet metal processing and manufacturing, microelectronics and other fields.

How to choose a good Resistance Spot Welder?

To determine whether the welded workpiece is ferrous metal or not, an AC spot welder is generally applied.

Because the AC spot welding machine adopts AC discharge welding, it is especially suitable for materials with larger resistance. At the same time, the AC spot welding machine can use single pulse, multi-pulse signal, cycle, time, voltage, current, and program control methods. The welded workpiece implements single-point, double-point continuous, automatic control, and artificial control welding. It is suitable for welding of tungsten, molybdenum, iron, nickel, stainless steel and other metal sheets, rods and wires.

Its advantages:

1. Better comprehensive benefits and higher cost performance
2. Wide range of welding conditions
3. Small and lightweight welding circuit
4. Dissimilar metals can be spot welded widely.

The disadvantages:

It is affected by the fluctuation of the grid voltage, the welding current of the AC spot welding machine will fluctuate with the fluctuation of the grid voltage, which will affect the consistency of welding.

The shortest welding discharge time of AC Spot Welding Machine is usually 1/2 cycle 0.01 second.

It is not suitable for high-standard welding of some special alloy materials. To determine that the material of the workpiece to be welded is a non-ferrous metal, an energy storage spot welder is generally applied. Because the energy storage spot welding machine uses energy storage capacitor discharge welding, it has the characteristics of small impact on the power grid, concentrated welding current, fast release speed, strong penetrating power, and small heat-affected area. It is widely suitable for the welding process of silver contacts, copper, aluminum, stainless steel and other metal sheets, rods and wires.

The advantages are:
1. The current output is more accurate, stable and efficient.
2. The welding heat affected zone is smaller.
3. Compared with AC spot welding machine, it saves more energy and saves energy.

The disadvantages:

1. The equipment is expensive.
2. The welding discharge time of the energy storage spot welder is affected by the energy storage and the welding transformer. After the equipment is finalized, the discharge time cannot be adjusted.
3. The discharge capacitor of the energy storage spot welder will automatically attenuate after long-term use and needs to be replaced.

How to verify that the material of the welded workpiece is phosphor copper. We should take an AC brazing machine to weld manganese copper or copper braided wire.

The AC brazing machine belongs to a sub-category of the AC spot welding machine. Therefore, the brazing machine also uses AC discharge welding. It uses the welding transformer’s duty cycle and is equipped with graphite (tungsten) electrodes to form a high resistance heating area. Pulse, multi-pulse signal, cycle, time, voltage, current, program control methods, implement single-point, double-point continuous, automatic control, and manual control of the welded workpiece.

Its advantages:

1. Better comprehensive benefits and higher cost performance
2. Wide range of welding conditions
3. Small and lightweight welding circuit
4. Dissimilar metals can be spot welded widely.

Its disadvantages:

1. It is greatly affected by the fluctuation of the grid voltage, that is, the welding current of the AC spot welding machine will fluctuate with the fluctuation of the grid voltage, thereby affecting the consistency of welding.
2. Higher requirements for electrode materials and shorter electrode life.

We should take butt welding machine regarding of wire material and bar material.

Butt Welding Machine is divided into two-stage butt-joining machine and three-stage butt-joining machine. Metal wire butt welding machine for metal halide lamps is also called hard wire guide wire machine. Metal wire butt welding machines for energy-saving lamps, fluorescent lamps, and ordinary incandescent lamps are also called soft wire guides.

We can choose an Intermediate Frequency Inverter Spot Welder to complete high-precision and high-standard welding for special alloy materials.
