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.
