Intermediate Frequency Inverter Spot Welder 220KVA Stainless Steel Spot Welder

Intermediate frequency inverter spot welder For stainless steel welding

Performance characteristics

The medium frequency DC resistance welding controller has the following advantages:
It is especially suitable for the precise connection of copper, aluminum, nickel, molybdenum, tungsten, manganese, gold, silver and other non-ferrous and precious metals. It is widely used in battery plants, electric light source plants, automobiles, medical devices, photoelectric communication plants, micro motor plants, and chip inductors and coils of high-temperature enamelled wire / ultra-fine enamelled wire (minimum 0.02mm) with high customer requirements, Metal wire welding, nickel cup, cutting wire welding, CCFL welding, fuse, filament welding, etc.
1. When AC current passes through the welding area, it diverges due to the surface effect. On the contrary, the DC current with small ripple output from the medium frequency welder has a "cluster effect" to the center when passing through the welding area. It can concentrate the welding heat and reduce the heat affected zone around the welding joint. This feature is particularly important for the welding of multi-layer plates and thick plates;
2. The output of medium frequency DC welder is continuous DC, with stable current and high control accuracy. Coupled with the bunching effect of DC, it can ensure that there is little or no spatter in the welding process.
3. The medium frequency DC controller outputs DC current with very small ripple and no zero crossing effect. Therefore, it has irreplaceable advantages in light alloy, heat-resistant steel, precision parts, high-speed seam welding and occasions with high welding quality requirements.

Spot welding electrode,

The spot welding electrode is composed of copper through water+electric welding head. Water cooling cycle can be carried out, which can protect the electrode and enhance the welding time.

Different welding points require different welding joints.

Comparison between medium frequency DC resistance welding controller and AC control

1. When AC current passes through the welding area, it will diverge due to the surface effect. On the contrary, the medium frequency welder outputs DC current with very small ripple
The welding area has a "bunching effect" towards the center. It can concentrate the welding heat and reduce the heat affected zone around the welding point. This feature is particularly important for the welding of multilayer plates and thick plates;
2. The AC welding machine adopts the AC chopping mode, so it has the characteristics of discontinuous current and high current peak, which causes the AC welding machine to weld
It is easy to produce a lot of spatter during the welding process, which will damage the surface of the weldment and bring a lot of work to the manufacturer. The medium frequency DC welding machine outputs continuous DC current, with stable current and high control accuracy. In addition, the bunching effect of DC current ensures that there is little or no spatter during welding.
3. The medium frequency DC controller outputs DC current with very small ripple, without zero crossing effect, so it has irreplaceable advantages in light alloy, heat-resistant steel, precision parts, high-speed seam welding and occasions with high requirements for welding quality.
