Cheap semi-automatic spot welding machine
• The direct pressure mechanism has good servo performance and fast welding speed: the guiding part adopts special material with small friction foce, and the electromagnetic valve and cylinder connect directly to speed the action speed, improve the beating speed, and reduce the loss of air flow.
• The service life is long and the noise is small. With the adjustment function of pressure speed, the upper and descending speed of the pressure head can be adjusted arbitrarily, and the impact the welds is reduced. With the function of rising buffer, it can adjust the ascending and buffering speed arbitrarily, reduce the mechanical impact and improve the service life of the cylinder block, and also reduce the noise.
• Safe and easy to use: high performance gas circuit filter cup with a shield, can prevent the glass breakage deb is splash, and also Protect the impact from the impact from the external. Cups and shields can be handled and easily overhauled.
1.Temperature protection switch to prevent Thyristor from overheating and breakdown.
2.Digital welding microcomputer Timer, ensure accuracy of welding time.3.End Output Signal can be sent to the other peripheral welding devices.
4.Japanese brand Timer, TETRA-K is also available, that provides constant welding current.
5.Application: Automobile, motorcycle sheet metal parts, metal box, computer case,
stamping parts and many others. Available in single or multi-point spot welded.
