Microcomputer high frequency inverter dc spot welder is the latest high-end spot welder developed and produced by our company. It is also the crystallization of our long-term production experience and technology. This machine adopts microcomputer control and ac/dc inverter technology, and its performance reaches the top level of resistance welding. The product is ahead of the domestic industry level, synchronizes with foreign technology, and can completely replace SEIWA, AVIO, MIYACHI, UNITEK and other foreign series spot welder products. cars onlyFeatures of welder: the machine adopts two driving modes: dual pedal-operated spot welding and pneumatic spot welding. 1. Double pulse welding: pre-welding and follow-up welding, pre-welding: remove the oxide layer to eliminate sundries and reduce the spark phenomenon.2, microcomputer control accurateThe micro computer inside the welding machine can scan the input voltage for a long time, the voltage fluctuates slightly, and the micro computer can calculate the compensation to change the welding energy immediately.3, stable current output: the machine adopts microcomputer single chip microcomputer control, fine current regulation, ensure stable output current.4. Simplified operation and setting: digitalization of various parameters, LCD display, touch keyboard adjustment, accurate, intuitive and simple.5, easy to use: needle spacing, pressure independently adjustable, suitable for fine components of welding, accurate alignment, high yield.6. Automatic alarm and disconnection system: if the welder is defective or the device is damaged during use, Chinese < waiting for > or < fault > will be displayed automatically, and the welding circuit will be automatically disconnected to prevent further deterioration of the fault and remind maintenance.7. Automatic counting: the daily output of single shift is 0000-9999, and the working efficiency of each team is significantly improved.8. Less after-sales maintenance rate and easy maintenance: in order to improve welding efficiency, 90% of the machine USES imported components to ensure a low failure rate.1. Power supply: AC 220V±10% 50HZ±5%HZ air pressure: 1.8-2.8kg2. Maximum output power: 10KVA3. Pre-welding current 00-99 welding time 00-30 welding current: 00-994. The welding stroke is 25mm and the welding height is adjustable5. Machine weight: 50KG6. External size of table: 800L×600W×1180H pneumatic model size :400L*370W*220H (unit :mm)7. Welding range: suitable for metal welding nickel sheet of 0.03mm ~ 0.1mm.Painted 8. Example: welding nickel metal hydride batteries such as lithium electricity, etc. With nickel alloy pills aluminum composite nickel band painted painted the connection of the wires connected to the guide of the household electrical appliance parts and painted painted wire welding metal accessories copper silver painted painted products combined with a stainless steel tableware periphery connection bulb painted painted foot welding strap buckle welding frames painted painted welded frame welding painted hair dryer heat conduction welding wire pole ears tea painted painted stainless steel tank sealing welding electronic components of various kinds of high or low conductive metal and alloy, etc 1. Output waveform: reflects the pulse state when the machine is working.·· when the welding current (WI) is adjusted downward, 'wait...' will appear on the display screen. At this time, the machine is in the waiting state.3. Pre-welding current (BI) : refers to the height of the first pulse, whose setting size is 0-99. Generally, the test machine is selected at about 35, and the size adjustment should be based on the actual welding current. Generally speaking, the welding current is large, and the pre-welding current increases correspondingly.4. Welding time (WT) : refers to the width of the second pulse, the total duration is 1-30ms, and the welding time is selected according to the specific welding effect, usually 10-20ms.5. Welding current (WI) : refers to the height of the second pulse, and its setting range is 0 -- 99. Generally, about 50 is selected for test. The size adjustment should be based on the actual welding effect.6. STATE: the image shows the 'on' and 'off' states when the photoelectric switch and the touch switch are working. The left part shows the working state of foot switch when 'pneumatic'; The right half shows the working state of photoelectric switch. When the welder is in discharge state, the two switches here are in 'closed' state.7. SWITCH: refers to the display state SWITCH.8. CLEAR: CLEAR the original setting and adjust it again. For the welder with counting function, press this button to count and restore the initial state: '0000'.1. Adjustment of Angle and height of pedal lever: loosen the locking screw of pedal lever with wrench first, then adjust its Angle and height (when stationary)The Angle is 90°) to the appropriate position, finally lock the screw. (pneumatic type does not need this adjustment)2. Needle height adjustment: loosen the needle height adjustment screw first, then adjust or replace the length of the needle below the exposed electrode (generallyAbout 25mm, too long welding needle easily deformation), in the lock this screw.3. Width adjustment of electrode welding needle: first loosen the width adjustment screw of welding needle with a wrench, and then adjust two electric charges according to the width of the welderMake the two welding needles to the appropriate distance, before locking the screw.4. Adjust the height of the object shelf: loosen the rotating screw of the object shelf, and then adjust the suitable distance between the touched welding workpiece and the welding needle (1Generally 3-5 mm or so is appropriate), in the lock this screw.5. Adjustment of welding pressure: turn the welding pressure knob by hand, and rotate clockwise to increase the pressure, and vice versa, according to the weldingThe requirements of the artifact are adjusted with appropriate pressure. Cylinder pressure adjustment is appropriately adjusted according to the thickness and flatness of the welded plate, generally about 3KG. When the welding effect is not firm, the cylinder pressure adjustment can be increased.6. Inspection: if the welding needle has carbon accumulation, remove the carbon accumulation with fine sandpaper, and then step on the pedal to lower the head, and visually check whether the welding needle is aligned with the required welding position, otherwise, it can be adjusted until the welding needle is aligned with the required welding position on time.7. Power on: plug the plug into the 220V power supply, turn on the power switch of the spot welding machine, and adjust the parameters according to the welding material and thickness.8. Welding test: step on the foot pedal to lower the machine head. When the welding needle presses on the welding part, continue to press down and discharge welding when the two welding switches are closed. Change the welding current and needle pressure according to the welding condition until the best welding effect. If the distance between the welded object and the welding needle exceeds the cylinder stroke or when the cylinder descends, the welding machine is not discharging and needs to be restarted once.
