Spot(projection) welders series: DTN-P-1(2)-L
DTN: Pneumatic AC mains frequency spot(projection) welders P: Rated capacity 1: Lower arm can not be adjustable; 2: Lower arm can be adjustable L: Throat depth, namely arms length
-
Machine body of thick steel sheet: The whole machine body is made of high-quality thick steel sheet through integrated stamping and welding processing. It has excellent structural rigidity and strong bearing capacity, which can effectively resist the vibration and impact generated during high-frequency welding operation. It avoids deformation, shaking or loose parts of the machine body after long-term continuous work, provides a stable and reliable working platform for high-precision welding, and greatly extends the service life of the equipment.
-
Secondary electric conduction parts is style of upper insulation.
-
The electrodes of speed can be adjusted at random: The running speed of the welding electrodes supports stepless random adjustment, without fixed gear limitations. Operators can flexibly and accurately adjust the electrode speed according to the material of the workpiece (such as metal wire, sheet metal), thickness, welding precision requirements and welding process. The slow speed can avoid impact damage to the surface of precision workpieces and ensure the integrity of the workpiece surface; the fast speed can improve the welding beat and production efficiency. It fully adapts to different welding needs and ensures the stability of the welding process and the beauty of the welding spot.
-
Microcomputer control, accuracy and steady, Can store 15 sets welding schedules.
-
Controller can automatically compensate current: The integrated controller has an intelligent automatic current compensation function. It can real-time monitor the grid voltage fluctuation, load change and other factors that affect the welding current during the operation of the equipment. Once the current is unstable or deviates from the set value, the controller will automatically adjust and compensate in time to ensure that the output welding current is always stable and consistent. It effectively avoids welding defects such as virtual welding, missing welding, over-welding and spark explosion caused by unstable current, and greatly improves the qualified rate of products.
-
Water cooling transformer: Use silicon sheets of 15000 gauss permeability to pile up.
-
Fast solenoid valve: The machine adopts a high-quality fast solenoid valve, which has the advantages of fast opening and closing response, sensitive and reliable action, and high control precision. It can quickly respond to the control signal of the microcomputer system, accurately control the action of the cylinder and the on-off of the gas circuit, effectively improve the welding beat and the repeat positioning precision of the electrodes, reduce the fault shutdown time caused by the slow response or failure of the solenoid valve, and ensure the continuous and stable operation of the production line.
-
Cylinder adopt high accurate, anti-friction hard material, which is duralumin.
-
Quality is stable, failure rate is low.
-
It is suitable for metal wire, electrical appliances manufacturing, metal plate process, micro-electron etc.
