Solid State High Frequency Tube Welder

Solid state high frequency tube welder for various round pipe, square pipe, rectangular pipe, oval pipe and special pipe like LTZ section welding featured with high efficiency and reliable.
Specification
Power:60-2400KW
Frequency:150KHz-600KHz
Characteristic: The low output ripple, the smoothly welding, reaching high output efficiency as high as 85% and still being able to adjust and troubleshoot conveniently.
 
1).Simple circuit and easy installation:
 The connection cables between the rectifier cabinet and inverter cabinet are less than ten pieces and are supplied together with the machine. The number of cables between rectification power supply and console is also very limited.
2).Complete protection and easy maintenance: The whole equipment setup morn than 20 kinds of protective measures. Maximum limit enhances equipment stability, and prevents the equipment was damaged:
All alarm message was sent to PLC system after corresponding processing by control panel. Through the display screen, maintenance personnel can easily understand the reasons for equipment failures and countermeasures.
3).Limited interference of resonance, not to contaminate power grid.
A number of well-matched filter network has been designed, in addition, the rectifier transformer’s isolation function so that harmonic components little when solid-state power supply operating at full power. The power factor may reach above 0.9
4).Safe, free of high voltage; fire-striking not likely to occur between inductor and steel pipe：The third generation all solid state high frequency power supply adopts special high frequency tank circuit parameter design which enables appropriate output voltage obtained at the inductor and thus prevents fire striking between the inductor and steel pipe and the stability of equipment is improved.
5).The efficiency is highest reaches above 85%, remarkable energy saving and limited consumption of cooling water: The advanced zero voltage zero current switch technology (the ZVZCS technology), eliminated the power component's switching loss.
6).Output ripple coefficient is less than 1%，No welding splash and the quality of welding seam is well：Power output is stable, welding seam the welding joint is in the shape of a bright line, The inner welding joint is basically a straight line. The first choice equipment for High accuracy welded pipe.
7).High reliability and stable operation：technology layout is reasonable ,design parameter is accurate.
8).Easy to maintain, users can self-repair: personnel has vacuum tube servicing experience to pass through training, may fully independent  maintain or the maintenance equipment.    
9).Equipment can be allowed to reduce rated power using when necessary：
When equipment has failure but want to product urgently, equipment can be reduced rated power using, convenient user for production.
10).All module of control boards are universal, free of adjustment.
