300kw Automatic High Speed Welding Steel Pipe Solid State High Frequency Welder
Function:
Solid state H.F welder is specially designed for straight seam welding. It adopts high power components of US IR IRFP460 MOSFET and Germany IXYS Company DSEI60-06A rapid recovery diode. The high power capacitor C and inductor coil L compose current-mode parallel upper-voltage resonance circuit, which doesn’t need output transformer. Thus, it not only improves the efficiency, but also increases the reliability of the welder.It includes Inverter Unit, DC power Unit, Central Control Unit, Water-water(air-water) cooling Unit, Rectifier Isolaiton Transformer.
Advantage :4S
1.Save power: Save 15%~25% of electric power than the 2nd generation welding machine. 2.Save time: Only take one day to install. 3.Save space: Save 60% workshop space. Save cost: Save cable lines, water pipe and cable trays between DC cabinet and inverter cabinet.

FAQ
Q: Are you a manufacturer?
A: Yes, we are a manufacturer. We have 4 factories ( Machining, Assembling, Heat treatment, and Moulding ). We also have our own R&D department. Welcome to visit us.
Q: What kind of payment term do you do?
A: We do T/T.
Q: What info do you need before giving me the price and proposal?
A: Since we design individual machines based on our customer's requirement, we need your desired products' basic dimensions, including all the pipe diameter(or tube length), thickness range, usage, raw material steel grade, coil weight, and degree of automation.
Q: What should I do if I just start a new business?
A: Contact us immediately, we provide a free consultant for pre-sales service. Also, we can help you solve the raw material (steel coil) purchase, worker training, international market price, and more.
Q: How do you do QA?
A:We have a special team to do strict QA, this is one of our strengths:
(1)Every gearbox will be tested for 8 hours with oil inside to guarantee there is no leak.
(2)Every shaft will be inspected for centering jumpiness.
(3)Every roller will be checked to make sure it's in the range of tolerance critical parts will be inspected for all dimensions.
Q: Why I should choose you? what are the differences between you and other Chinese suppliers?
A: We are concentrating on pipe-making machines for more than 20 years. We have constructed many steady trading partners in Asia, Africa, the middle east, Europe, and South America throughout the years. Our innovative designed production line and every single unit of the production line are economical and practical.
