Welding equipment system structure features fold: 1. spot welding system consists of a mechanical device mechanical devices, power supply unit, a control unit composed of three parts. Spot welding the welding process in order to meet the requirements of Huizhou Chivas plastic welding equipment manufacturers, pressing mechanism (welding clamp) with a double stroke fast pneumatic mechanism, changing the opening of the welding clamp stroke by switching control handle, can be divided into large and small open Open to meet the requirements of the welding operation. Normal state for a short trip welding clamp open, when the control button to switch to the "on" position, then pull the handle switch welding clamp tight pressure welding equipment, welding current to complete a cycle in the control system after recovery to short stroke open position. 2. The power supply unit from the main power circuit resistance welding transformers, SCR unit, the main power switch, soldering circuits and other components. Currently, welding equipment we use is the power 200kVA, secondary output voltage of 20V single-phase AC power frequency resistance welding machine. Due to a variety of models collinear production, welding clamp to be welded high-strength steel and low carbon steel sheet, welding clamp gun arm to pass large mechanical force and welding current, welding clamp strength, stiffness, high fever must meet certain requirements frequency welding equipment - find Huizhou China disabilities, and to have good electrical and thermal conductivity, and requested the use of water cooling welding clamp, welding clamp electrode arm so I chose to be able to withstand the pressure of the new welding clamp 400kg. 3. The control apparatus for a resistance welding machine is mainly to provide a signal to control operation of turning on and off the welding current, the welding current control, monitoring and fault handling. (4) inert gas welding equipment manual inert gas welding equipment, including torches, welding power and control devices, gas and water supply systems of four parts. Supply of welding equipment - Huizhou Chivas, Chivas welding (certified), welding equipment from Huizhou City Huashi Welding Equipment Co., Ltd .. Huizhou City Huashi Welding Equipment Co., Ltd.
