1) Three control functions: constant primary and secondary current, constant voltage;
2) Automatic adjustment of welding power and welding current;
3) Ensure the automatic cycle of each program segment of welding process in order to achieve complete automation;
4) When the current is too low, it will automatically electrify to conduct repair welding;
5) Be able to use the control panel to set parameters for different welding models directly. Convenient operation, easy adjustment;
6) Both single welding and continuous welding are available and each welding cycle has three welding conditions;
7) The intensity and time of welding current of each welding condition could be set separately. In the meantime, the current could be set to gradual up or down;
8) Pneumatic control (action output); the pneumatic control could be delayed;
9) Be able to store 9 types of welding models. Be able to select and adjust different welding models by choosing the number of models;
10) Silicon controlled adopts phase shift to trigger and the synchronous voltage is from the grid voltage to ensure the silicon controlled and grid will conduct synchronous phase shift trigger so as to achieve precise adjustment of the welding current and to meet the requirement of welding different materials;
11) When the power grid voltage fluctuates, the automatically compensation can make the welding current more stable. Thus, the welding quality could be guaranteed even though the grid voltage is under bad situation.

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 suitable Technical 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 Union, Alibaba trade assurance. (we prefer you to choose the Alibaba trade assurance order. If you are not satisfied with the machine that you order, or we delay the shipping time, then you can apply the complaint on . )
Q8: 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 installation and training. But there will be extra cost for Engineer, including the salary, visa cost, round-trip ticket cost, and accommodation fee will be covered by the buyer.
