An overview of pressure magnitude and scope of the welder working stroke of the pneumatic pressure control mode with automatic semi-automatic welding equipment, electrodes can be adjusted within the set range. Mainly applicable to all kinds of sheet metal structure of the workpiece spot and projection welding, widely used in automobile parts, motorcycle parts, steel radiator change radiators, solar water heaters, metal containers, steel safes file cabinets, wire mesh filter equipment and other manufacturing industries, welded joints can ensure adequate mechanical strength welding, it was equipped with high-performance, high-reliability KD3-160B microcomputer projection welding controller, which can be achieved pressing, welding, maintain, resting four welding program procedures, depending on the work required can choose single spot welding and spot welding continuously cycle. Compared with similar products, it has a simple and intuitive operation, output power, welding speed, a significant advantage of the device failure rate, etc., to meet the user's various welding needs. Second, the structure outlined a welding transformer equipped with rated capacity from 25KVA-150KVA transformer depending on different welding workpieces, welding inside. The transformer coil using disc coil structure, the primary coil 4-6 disc coils, contacts outside the group can be changed via parallel or in series to the coil, thereby obtaining 8 different output voltages, specific to each specification The transformer has different technical parameters, see table 2 below. Secondary winding copper plate using two to three topical circle water cooling pipes and the bus plates, busbar role is to connect the secondary coil, while meeting with the output electrode soft copper connections, busbar design generally on water cooling system. In order to improve the reliability of welding products, some welding has been canceled and the insertion of the contact group, while the welding transformer connected directly into seventh gear (or maximum file 8th), the output voltage of the regulator is to rely on computer KD3-160B projection welding welding power controller knob to achieve stepless adjustment. 2, the upper and lower electrodes and the upper and lower support means welding electrodes were installed in the electrode arm, when the need for welding, vertical movement of the electrode in a straight line down under the action of the cylinder, after pressing the workpiece welding. Since different parts of the structure of the welding, the welding electrode size and shape will be changed accordingly. The connecting portion of the electrode tip needs good conductive grip to reduce heat generation, electrode grip also need to pass water for cooling. 3, pneumatic compression devices pneumatic compression devices on this welding machine by an air compressor (user-owned), air source treatment element, solenoid valve, flow control valve, working cylinder composed of several parts. Air compressor for the air supply equipment, the purchase by the user according to their own needs, generally choose low pressure 0.2-1.0Mpa vane type air compressors, it has small size, light weight, low noise, small amount of maintenance and long life Features. Installation and use on air compressors, please refer to the technical information related products. You must consider when installing the surrounding air clean, low humidity, in order to ensure quality of inhaled air, while strictly abide by state regulations limit the noise, if necessary, can be soundproof isolation noise. Air preparation by the filter pressure mist triplets or two conjoined components. Its role is to: 1 filter impurities in the air and water filter with automatic drain and artificial drainage of two drainage patterns, welding will be conducted in accordance with stock material for artificial drainage watershed filter to regular drainage, automatic Drainage automatically drain when the compressor switch, no matter what the drainage way, when the filter in the water level near the filter, drainage work must be carried out to ensure the watershed filtering effect filter; the role of regulator of 2 cylinder electrode is desired gas pressure was adjusted to an air compressor sent, and maintain a stable pressure in the working cylinder does not change, and the regulator pressure gauge reading electrode correspondence as shown in Table 4; 3 mist the effect is to stabilize the pressure of the gas in the atomization add some oil, gas line along the loop to the solenoid valve and cylinder, which lubricates the electromagnetic valve and the cylinder. Oil generally choose 22 turbine oil or used car 4T motorcycle oil, gas atomization drip volume adjustment is to rely on the upper end of a lubricator adjustment knob to achieve, the amount is too small to achieve its proper drip lubrication the role is too big drip lubricant loss will accelerate, but also pollute the surrounding environment. Flow control valve: in the pneumatic system circuit is used to control cylinder speed of movement, using the process to adjust the air flow by adjusting the knob to adjust the cylinder moves to the pace. In actual use, should be selected through runoff valve according to the circuit requirements for effective cross-sectional area. When you install the flow control valve should be located near the cylinder port, so as to better work. The welder uses a one-way throttle, just under the speed of the cylinder pressure adjustment. Solenoid control valve: solenoid control valve role is to change the direction of motion of the cylinder by means of an electrical signal, the machine uses two five-way pilot-type single-coil electromagnetic valve, the main features of commutation speed, consumption power, low noise. Noise reduction welder at work, both on the solenoid valve vents are installed noise muffler. Working cylinder: Work is an actuator cylinder pneumatic components, its role is to pressure into linear motion, and the pressure applied to the upper electrode welder, which play a role in pressing the workpiece. The welder uses a cylinder of light cylinder with buffering function, buffer size adjustment can adjust the buffer cylinder ends of adjustment screws. 4, computer control of the welding projection welding welding controller uses KD3-160B microcomputer projection welding controller, which can be achieved pressing, welding, maintenance, rest four basic projection welding welding procedure, and You can select single cycle welding and automatic continuous welding function. Pressing time, duration, rest time can be adjusted in the range from 0.1 to 4 seconds adjusted, the welding time can be adjusted between 0.02 to synchronize 3.98 seconds, the welding energy can be between 10% to 99% adjustment, the controller having grid voltage automatic tracking compensation, the workpiece can be further improved weld quality. Details concerning KD3-160B computer projection welding controllers, please refer to the product's instructions for use. 5, the housing of the welder welder chassis enclosure housing with steel materials processing, manufacturing, guides and all parts welding cylinders are fixed to the housing. Guide sleeve means gray cast iron cylinder manufacturing, the guide shaft carefully processed using 45 steel, guide sleeve is to prevent the lateral force generated when pressing the welding cylinder piston rod, cylinder harm, at the same time guide to prevent electrode connected to a radial axis of rotation. Guide sleeve and the guide shaft part of the work needed filling oil for lubrication. Third, equipment placement and installation to ensure the normal operation of the welder, welder should be placed in ventilated, dry, wet, no dust, no acid salt corrosion, where no big vibration, ambient temperature should be -10 ℃ - + 30 ℃, relative humidity less than 65% of environments, it is possible to affect the normal operation of equipment when the environmental conditions are not meet the above requirements, you may have a serious welder and weld controller causing failure delayed the user use. The welder hosts placed on relatively flat ground level, it is best if the conditions using the foot screws, which can increase the stability of the welding work, users can not lengthen or replace the welding electrode arm other specifications, so as to avoid Effect of welding power and welding results. The welding power source used should comply with the requirements of the power supply voltage and frequency, should take the necessary protective measures of protection when a high-frequency electrical equipment near the welding, when the power supply voltage fluctuation range is large may affect the welding quality of the workpiece. Because welder welding power is relatively large, you must install the appropriate knife switch and power cord in accordance with the table in claim 5, welder is best to use a single piece with leakage protection and overload protection automatic air switch, do not easily increase the Knife switch fuse capacity and the use of copper wire in place of safety fuse, or not achieve proper protective effect when the welder fails, there may even burn welder welding transformer and a control section. The use of the power cord should be used in the data table is not less than the copper wire, to ensure the normal operation of the welder and the operator's personal safety, this welder should be grounded before use, grounding resistor should comply with electrical equipment grounding Safety requirements. Fourth, the use and commissioning of equipment 1. Turn the power switch on the power control. 2. Turn on the air compressor power switch, adjust the air pressure and flow to the right place. 3. Turn on the cooling water, welding the welding transformer, welding electrode cooling. 4. Turn the controller power switch, the power indicator should light. 5. Run the debugging playing in debugging position (only the action is not welding). 6. Depress the foot control switch, check the pressing time, the time is appropriate to maintain the principle of disposal is to be pressed after power welding, or easy to damage the welding electrode and the workpiece, the pressing time for insurance purposes should be higher than the actual movement of the cylinder a little time longer appropriate. Rest time is to adjust the cylinder return time can be adjusted as needed, generally does not affect the welding performance. 7. Check the welding electrode surface smooth, can not have attachments and surface flawed. 8. Adjust welding power controller to the appropriate welding specifications, such as the case of uncertainty should be selected smaller welding energy, for a plug to downshift welding transformer must also shift down (see table 2), Avoid welding power is too great damage to the workpiece and the welding electrode welding. 9. debugging action is not a problem, you can run the debugging of the controller to move the operating state, carry out test welding work samples, you can find some scraps welding, depress the foot switch when welding, the welder will automatically perform the entire welding process of welding parameters and chronological order according to the original setting. Program of its work as:. A pinch. . B welding; the cylinder control electrode pressed downward movement of the workpiece to be welded. Assemble the predefined welding energy, welding time, welding pressure welding operation; c maintain. Cylinder continue to be applied to the welding work welding pressure for some time after welding is complete, in some cases need to use a pressure greater than forging welding performed in order to improve the welding performance; d repose. A control electrode of the return process. After welding of the workpiece inspection, when the welding parameters is small may live or insufficient solder bonding strength, it should increase the welding parameters so as to meet the welding requirements, when larger welding parameters is also possible to burn through in welding workpieces leaving the upper electrode welding slag, it should first clean welding slag welding electrodes, welding parameters and then continue after the transfer of small test welding until the welding process requirement. Between the upper and lower welding electrodes 10. If there is no place to welding work, not down on the foot switch short-circuited air welding, or they may burn the welding electrodes, welding transformer cause harm, we must pay attention to this point. For more information about using the controller's operation, see KD3-160B computer and projection welding controller instruction manual. V. Cautions 1. welder welder must be grounded before use, do not take the protection of ground can not use the welding equipment, protective grounding wire grounding resistance ≤5Ω, to ensure the safety of the operator. 2. welder through water before being welding. Each active portion welder should be kept lubricated, weldments should clean up after welding in order to avoid damage to the electrode or affect the service life of the welding electrode. 3. When welding temperatures below zero degrees Celsius, the After welding should use compressed air to blow remaining in the cooling circuit of the cooling water to avoid frozen pipes and the cracking of the welding transformer. The welder should be inspected and maintained after a power failure, operation of the workers should wear gloves and canvas around the body of work, in order to avoid burns. 5. welder can not damp to prevent leakage. Not a long time before you use the welder is qualified to check the insulation resistance, insulation resistance welder 500V megger test between the power line and the shell is not less than 2.5 megohms before electricity use. There should be no use of space within 6. welder welder seriously affect the insulating properties of the corrosive gas, chemical sediments and corrosive, explosive, flammable media. 7. The welding work should be strictly in accordance with the rated duty cycle of work, are not allowed to overload. 8. trap filter air source treatment unit must always drain, water level should not exceed the warning level, compressed air or water will enter the mist and solenoid valve cylinder, resulting in accelerated wear of the cylinder valve can not even work properly.
