High Frequency pipe welding machine

Product Description (Finning Machine)

This machine produces fin tube without tube connector.
So it doesn't need to stop machine to connect tubes and it possible to produce big size tube by changing tube chuck. Highly skilled operator is not required because each part of system are linked each others and automatically driven by pushing the "Start Button".
This machine has uniformed welding quality due to automatic adjustment welding power depend on welding speed. In case of electric arc, the machine protect the tube by means of spark detector, plate and grid O.C.R. devices so minimize tube damage. Also each systems in the machine has double protection systems so to prevent the machine damage.

Major Achievements

From the verification of product excellence in local market and improvement of product quality and increased competitive power in world’s market, we are exporting our product to overseas markets including Japan, Malaysia, China, Iran, India, Iran, Russia & Slovakia. We are continuously developing and proving verification of our product quality not only in local market but in the huge world’s market as well.

<< Welding Part >>

It is the system for welding fin with tube and consists of cooling nozzle for fin tube, high frequency output transformer, up & down table for adjusting the position of transformer, fin guide roller and tube break roller with strong and stable systems.

Guide roller which is easy to connect and change fin with tube is air cylinder type for more efficiency, There is a spark detector which is installed for rapid stop of rotating tube in case of fin break so as to minimize and prevent breakage of tube and output transformer.
