350A-500A yellow board material

This is a set of 350A-500A specification gas shielded welding gun insulation sleeves (made of yellow sheet material), which are the core insulation accessories of welding equipment. They are used to isolate the conductive parts of the welding gun from the external structure and protect the electrical safety of the welding operation. Their detailed characteristics are as follows:

Material and Structure

Main material: Made of yellow board material (phenolic resin laminated cloth board), it has excellent insulation performance, high temperature resistance (based on actual reports), and mechanical strength. It can maintain structural stability in high temperature environments (≤ 200 ℃) during welding, and has excellent effect in preventing leakage risks.

Structural design: Integrated metal connection components (made of brass material) are used to fix on the conductive rod or connecting rod of the welding gun. After assembly, the connection is confirmed to be tight and the insulation performance is excellent; The surface is equipped with installation positioning holes, which facilitate detailed assembly with other components of the welding gun.

performance advantage

Excellent insulation: The yellow sheet material has high insulation resistance, which can effectively isolate the welding current of 350A-500A, prevent the welding gun shell from being charged, and protect the safety of operators.

Strong adaptability: compatible with gas shielded welding guns of 350A-500A specifications (such as industrial grade CO ₂/MAG welding guns), meeting the insulation requirements of high current welding scenarios.

High practicality: Yellow sheet metal components are prone to corrosion and aging, and the metal connection parts are wear-resistant, making them less likely to be damaged during high-frequency and high current welding operations, reducing the frequency of component replacement.

Application scenarios

Widely used in industrial grade high current carbon dioxide gas shielded welding (CO ₂/MAG welding) scenarios, such as heavy-duty steel structure processing, automotive manufacturing production lines, large equipment welding, etc., it is a key insulation component of high current gas shielded welding guns that needs to be regularly checked for insulation performance and replaced in a timely manner.
