Compared with the ordinary AC resistance welding, MFDC resistance welding has such special functions as high control precision, energy saving and high welding quality. MFDC resistance welding technology will certainly become the trend of the development of resistant weld.
WTC/MEDAR always spares no pains on the development of MFDC resistant welding inverters and controls.
The picture shown is the 5th generation inverter of WTC/Medar. It uses SCR to charge up capacitance. There’s an obvious improvement in its reliability and stability. The current capacity grade ranges from 400A to 4000A as per 10% duty circle rate. All the above advantages and reduction of the product’s cost make it have a glorious popularizing outlook in every industrial department. Take 2000A inverter for example, if a weld transformer is equipped with turn ratios of 1:38, the secondary welding current has reached 76000A, which provides vigorous support for high quality light metal welding.
Timer adopts new high-speed microprocessor. It can be collocated to adapt to needs of various welding applications, but also to process the welding calculation such as TFF and CHC.
The late-model Ethernet DEP (EDEP) has two specifications. The first specification is used to program and collect data on the spot to spot control local area Ethernet
Interface. The second specification is used to operate by connecting with plant’s Ethernet network. The local Ethernet interface and the serial interface can also be operated in portable computer. In order to meet different needs from different countries’ customers, eight different kinds of languages can be altered.???
It is an essential trend to make a substitution of integral transgun for fission welding gun, but the safety issue of welding gun follows. The integral welding guns manufactured by cooperation between Shanghai Medar and Korea Nawootec including AC Type, MFDC and Robot are equipped with WTC controls, which completely guarantees safety.
WTC/Medar has developed Ground Fault Module (GFM) installed in controls. GFM has the capability to self-check. It’ll check itself every time it is switched on and once at least every 25 hour. If there’s any abnormal, it’ll stop welding immediately.
As a joint venture between WTC/MEDAR RoMan Inc., Shanghai Medar Welding Equipment Co., Ltd has great advantages in MFDC resistance welding technology application. In recent years, Shanghai Medar has successfully manufactured quite a lot of MFDC welding machines with use of WTC/MEDAR MFDC controls and RoMan MFDC transformers. These machines we manufactured have been widely used in airplane and aerospace, rails transportation, electrical appliances, medical appliance, auto and other industries. We call for building an economical society nowadays, so it is our responsibility to offer more environmental protective, much safer and more energy saving products to our society.?? |
