DN Pneumatic Spot Welder

Performance characteristics:

1. Adopt high-precision guide mechanism, the piston rod is pressurized, and the followability is good. The solenoid valve is directly connected to the cylinder to speed up the reaction speed and reduce the loss of air flow.

2. Long service life and low noise. Equipped with a pressurizing speed adjustment function. The descending speed of the pressurizing head can be adjusted arbitrarily to alleviate the impact when pressing the welding object. Mechanical impact improves cylinder life and reduces noise.

1. Safe and easy-to-use high-performance gas path system. The filter cup is equipped with a shield, which can splash debris when the cup is broken, and can also protect the impact of external favorite collisions. The cup and shield can be mounted and disassembled for easy maintenance.

2. It adopts the cyclic forced cooling method, which is convenient to remove water blockage, improve the cooling performance of the equipment, avoid waste of water, and greatly reduce the amount of cooling water.

3. It adopts high-strength body structure, good rigidity, strong impact resistance and vibration resistance, which can prevent the electrode tip from sliding during welding pressure and achieve stable welding.

4. The simple and practical secondary conductor upper insulation method can avoid the adhesion of iron filings or short circuit accidents in the insulation parts that are easily generated when the lower seat is installed with welding tools.

5. It adopts microcomputer control system, with two control modes of constant voltage / constant current, two-stage discharge function, can accurately control welding time and welding current, and is easy to adjust.

6. Adopt water-transmitting transformer, high-permeability silicon steel sheet, secondary overall structure, large output current, energy saving and environmental protection, and long service life.

7, using high-power SCR non-contact switch water-cooled high-power thyristor elements, the output current is strong, stable and reliable.

8. The solenoid valve adopts Taiwan "Yadek" special solenoid valve, which has fast response speed and low failure rate.

9. In the secondary circuit with high conductivity and low power loss, the secondary output on the main transformer adopts multi-layer high-toughness and high-conductivity copper flexible tape, and it is V-shaped connection, which greatly improves the service life and lower secondary output. The integrated connection mechanism reduces power loss.

10. The spot welding head and electrode are made of high-strength chromium-zirconium-copper material, which has the characteristics of high abrasion resistance and high temperature resistance, which can reduce the cost of electrode materials for users.

use:

It is widely used in various wires and boards. Tubes, shaped copper. High quality welding of aluminum, iron, stainless steel and other metals.
