Precautions for Intermediate Frequency Spot Welding Machine

Selection of Current Adjustment Switch: Choose the level of the current adjustment switch based on the thickness and material of the workpiece. The power indicator light should be on after powering on. Electrode Pressure Adjustment: The electrode pressure can be adjusted by the spring pressure n... Read More

Analyzing Electrode Materials for Intermediate Frequency Spot Welding Machines

Intermediate frequency spot welding machines require electrodes to complete the welding process. The quality of the electrodes directly affects the quality of the welds. Electrodes are mainly used to transmit current and pressure to the workpiece. However, using inferior electrode materials can a... Read More

Detailed Explanation of Intermediate Frequency Spot Welding Machine Guide Rails and Cylinders

The moving parts of the intermediate frequency spot welding machine often utilize various sliding or rolling guide rails, combined with cylinders to form the electrode pressure mechanism. The cylinder, powered by compressed air, drives the upper electrode to move vertically along the guide rail. ... Read More

What is the power heating stage of a medium frequency spot welding machine?

The power heating stage of a medium frequency spot welding machine is designed to create the required molten core between the workpieces. When the electrodes are powered with pre-applied pressure, the metal cylinder between the contact surfaces of the two electrodes experiences the highest curren... Read More

What is the forging stage of medium frequency spot welding machine?

The forging stage of a medium frequency spot welding machine refers to the process where the electrode continues to exert pressure on the weld point after the welding current is cut off. During this stage, the weld point is compacted to ensure its solidity. When the power is cut off, the molten c... Read More

Why Medium Frequency Spot Welding Machines Need Cooling Water?

During operation, medium frequency spot welding machines have heated components such as welding transformers, electrode arms, electrodes, conductive plates, ignition pipes, or crystal valve switch. These components, which generate concentrated heat, require water cooling. When designing these co... Read More

Explaining Electrode Pressure in Medium Frequency Spot Welding Machines

The high-quality welds produced by medium frequency spot welding machines rely on electrode pressure. This pressure is the value presented by the pressure reducing valve when the upper and lower electrodes make contact. Both excessive and insufficient electrode pressure can decrease the load-bear... Read More

What to Pay Attention to When Operating a Medium Frequency Spot Welding Machine?

Electrical Safety: The secondary voltage of a medium frequency spot welding machine is very low and does not pose an electric shock risk. However, the primary voltage is high, so the equipment must be reliably grounded. The high-voltage parts in the control box must be disconnected from the power... Read More

The Working Process of Medium Frequency Spot Welding Machine

Today, let’s talk about the working knowledge of medium frequency spot welding machines. For friends who have just joined this industry, you may not know much about the mechanical use and working process of spot welding machines. Below are the three main steps of the working process of a me... Read More

Factors Affecting the Current of Medium Frequency Spot Welding Machines

During the welding process of medium frequency spot welding machines, the operating frequency is limited by 50Hz, and the minimum adjustment cycle of the welding current should be 0.02s (i.e., one cycle). In small-scale welding specifications, the time for zero crossing will exceed 50% of the pre... Read More

Inspection Work for the Quality of Spot Welding in Medium Frequency Spot Welding Machines

The welding pressure in medium frequency spot welding machines is a crucial step. The size of the welding pressure should match the welding parameters and the properties of the workpiece being welded, such as the size of the projection and the number of projections formed in one welding cycle. T... Read More

Introduction to Medium Frequency Spot Welding Process Knowledge

Factors affecting the quality of spot welding in medium frequency spot welding machines include: current, electrode pressure, welding material, parameters, energizing time, electrode end shape and size, shunting, distance from the edge of the weld, plate thickness, and the external condition of t...
