IGBT integrated hf tube welder
IGBT integrated hf tube welder take induction heating as heating method , water cooling system. All in one design could save much room and much 
more efficient compared with traditional hf welder . 

• The new generation HF welder adopts PWM chop-wave technology and DPLL inverter control technology .DC Chopper is used to cut the power supply voltage properly to
• achieve the voltage change of the teminal load. 

• Product Name: integrated solid state hf induction welder 
• Application : Used for ERW tube mill welding of round pipe , square tube and rectangulare pipes . 

• Advantages of solid state integrated HF tube welder  
•  1. High Efficiency    Compared to traditional tube/ pipe solid state induction welding equipment, save power up to 15%~25%
•  2. Less Area Covered  Saving 35% area than traditional solid state welder
•  3. Esay Installation  Comparing to 5-7 days for traditional welder installation, integrated HF welder  installation is only 1 day. 
•  4. Less Installation Cost  Take 100kw HF welder for example, the traditional installation cost is around USD700 (purchasing cable, nozzles,
•      cable bridge and brackets), moreover, welder room or elevated platform is necessary, all cost will be about USD700-USD1000 .
•  5. Welding Quality Benefitted from PWM precise control voltage and three level of filtering, the output voltage is stable, ripple coefficient is 50% lower than
•      traditional welder. The welding quality is obviously better than tradtional solid state welder.
