Medium Frequency DC Spot Welding Machine For Copper Relay / Shunt Electrical

Medium Frequency DC Welding Machine for Electrical Copper Relay / Shunt

Description Of Medium Frequency DC Welding Machine

MF DC Spot Welder is one of the newest resistant welding technology.

The advantage is that it helps to greatly reduce the energy of iron core material, as the frequency of welding transformer is promoted from 50/60Hz of mains supply to 1000Hz.

Besides, the commutation diode of subloop of transformer could transform the electric energy into DC power which is used to provide power for welding.

Under such circumstance, the inductance coefficient of subloop could be improved dramatically and the production cost could be minimized because the inductance coefficient is an important factor that results in energy loss but could almost be ignored in DC welding circuit.

Feature Of Medium Frequency DC Welding Machine

1) Advanced welding machine, adopt principle of MF inverter . Change the three phase AC power into DC power.

2) Welding current is DC , no inductance , higher heat input and output efficiency , more reliable and stable welding quality.

3) Intelligent digital controller, more precise and faster control of the welding current. The adjustment precision is 20 times higher than the AC machine.

4) Reduce the production cost, save energy, reduce the requirement for cables and maintenance cost, improve the induction factor.

5) Store energy in a special inverter, more adaptation to the fluctuation of the power grid.

6) Smaller size and lower weight of welding transformer, one third of the AC machine .

7) Be able to weld aluminum and galvanized material product.

8) Especially suitable for welding three-layer metal sheet or very thin product.

FAQ:

Q1: 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 the following 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 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 alibaba.com. )

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.
