Workpiece. - Universal application - Upper arm of machine is insulated, no short circuit. - Machine body of thick steel sheet, not easy to deformation, good rigidity. - Microcomputer control, accuracy and steady - Water cooling transformer: Use silicon sheets of 15000 gauss permeability to pile up. There is cooling water in inside, using full copper alloy core not aluminum, reducing impedance, improving the utilization of power, 20% duty cycle to ensure the requirement of long time welding, big output power. The useful lifetime is longer, noise is smaller, structure is more compact and reasonable. -Fast solenoid valve, making welding speed faster, thereby the productivity is higher, therefore decreasing cost. - Cylinder adopt high accurate, anti-friction hard material, which is duralumin, without rust, lower friction, lower noise and loading is faster, thereby reducing the weld spatter. - Lower loose weld rate, less welding dregs. -It is easy to operate machine. Performance of machine is more steady, can be used 24 hours, lifetime 15 years.     Our Guarantee!!1. One year guarantee time since machine leaves the factory2. Free component changes under the normal condition3. Our engineers will be sent to help the installation, debugging and training Company ProfilePackaging & Shipping FAQQ1: What is the price of your machine?Answer: our machines are customized for your requirements. If you want to get the appropriate price, please provide us thefollowing information.* The material and thickness of your product* The minimum and maximum size of your product* The welding position of your products* The automation level that you want to achieve* It would be better if you can provide us the detailed product drawings so our engineer can come out with the suitable technical proposal and price for you.Q2: What is the warranty period of your machine?Answer: our standard warranty period is one year after shipment. If you want to extend the warranty period, there will be extra cost. Q3: What if my machine damaged doing the warranty period?Answer: firstly, our engineer will help you to diagnose the problem via online guidance. if any parts damaged during the warranty period, we will send the parts to you for replacement free of charge. If you can not fix he problem by replacement of the new parts, we will send engineer to your factory to help fixing the machine.Q4: What is the delivery time of your machine?Answer: it depends on the complexity of your machine. Most of our standard machine we got in stock, then we can shape the machine with the seven days after receiving your payment. If you need the Customized machine, normally it would take about 30-90 days to complete the machine.Q5: Can we send the sample to you for welding test?Answer: yes. You can send us the samples for welding test and we will send you the pictures and videos after the testing. If you need, we can also send the samples back to your country so you can check the welding quality by yourself before ordering the machine.Q6: Can you provide us the machine drawings and technical proposal?Answer: yes. After receiving your detailed requirement and product drawings, our engineer will come out with the suitableTechnical proposal with the basic machine concept drawings to you. Be size after you placing the order we will send you the more detailed design drawings of the machine to you for confirmation. Only after you confirming the drawings then we will start the manufacturing process.Q7: What's your payment terms?Answer: we can accept the following payment terms: T/T, L/C, Western UnionQ8: How can we install the machine?Answer: for some simple machines we will provide you the english operation manual, the operation video and also we will provide you the online guidance and training to your engineer so you can set up the machine easily. For some complicated machines, we will send engineer to your country to help insta
