Intermediate frequency welder
Product Introduction
Intermediate frequency point convex welder series：DTM-N-P
DTM：Intermediate frequency point convex welder
N：Number of transformer
P：Rated capacity
For example: the rated capacity of 90 kva intermediate frequency point convex welder is expressed as DTM - 90
Main Features：
Intermediate frequency dc inverter type point convex welder is the resistance of the current international advanced welding products. Widely used, the welding transformer is small in size and large output energy. Used in the automobile industry is one of the asana transformer electrode holder more see its superior place. Its superior performance is due to the welding transformer frequency by the mains current 50/60 hz to 1000 hz, greatly reducing the weight of the core material, plus the transformer secondary circuits of rectifier diodes used to convert electrical energy into dc power supply welding; This can greatly improve the secondary loop inductance value, this is an important factor which causes capacity loss, almost in the dc welding circuit can not be considered, thus reducing the production cost to a very low.

Save save electricity：
Save energy improve the power factor including save each point of welding energy and shorten the cycle reduce the production cost. To the load balance of the power supply equipment fluctuation of power grid and the pressure drop of stronger adaptability more accurate and fast power flow control compared with low frequency system performance more and more accurate analysis of the parameters. Faster to set current: intermediate frequency when adjusting the welding current 20 times faster than the traditional technology. Resistance welding process more reliable: most of the application of metal using dc welding effect will be better to reduce production process.
Compared with traditional welding machine has the following advantages：
High energy saving: low welding current and electrode pressure;
High quality: compared to traditional welding machine the welding stability is another model There is nothing comparable to this;
Low cost: three phase power balance input high power factor the electrode life is more than 1 times more durable than the traditional;
High efficiency: can be done in a shorter than the traditional model of spot welding time improve production speed.
