Feature of Inverter spot welding system V6: Zinc galvanized metal plates are often used in car bodies. Zinc has a lower melting point (9500F) compared to steel (22500F). A single welding pulse will cause splatter in zinc plates affecting the weld quality. With Inverter technology, precise multiple pulse welding current is used to weld galavanized plates. A first lower current pulse melts and vaporize the zinc and pre-heats the welding zone. Subsequent pulses at higher current melts and fuses the plates together. Appropriate welding waveforms are built into the inverter spot welder to suit different types and thicknesses of different steels to achieve consistent and strong spot welds. (1)A variety of welding waveforms with single and multiple pulse modes for precise welding control. (2)Microprocessor controlled three phase inverter (MFDC 2000Hz). (3)High quality spot welds on various types of steels such as HSS, AHSS, UHTS, galvanized and stainless steels. (4)Over 200 pre set programs according to the types and thickness of the materials used and choice of welding clamps. (5)Maximum spot welding current 12000A (6)Standard equipment include water cooled clamp, air cooled cables and built in water cooling system (7)The main component have UL and CE approval: Breaker, contactor, screen, IC, IGBT, rectifier relay, Capacitor. (8)Large 5 x 7 inch colour LCD control panel with graphical interface and conveniently placed Button functions (9)Pneumatic pressure sensors - protects against over and under pressure situations (10)Lightweight C-clamp and manual gun for single sided and stud welding operations (11)Cleaner welding current, therefore less interruption to shop electrical system (12)Sense the voltage and auto-compensates for the power source (13)Double piston cylinder with upto 350 DaN clamping force (14)Software in CPU is upgradeable through internet access (15)Ideal for bodyshop repairs and production works (16)Monitors and control the spot welding process (17)Stored spot welding programs are customized (18)Bi-lingual display, change on - the -fly (19)Less consumption of primary power (20)IGBT component made in Japan (21)ABB switch and contactors Specification of Inverter Spot welding system V6: Input Voltage(50/60Hz): 400V 3pH or 208-240V 3pH Max absorbed power(KW): 73 Rated power x=50%(KW): 25 Max welding current: 12000A(3pH) Max short circuit current: 13000A(3pH) Power factor(cosphi): 0.8 Secondary no load voltage(V): 4-21 Duty cycle(%): 5 Inverter frenquency(Hz): 2000 Cooling system: Air(2 fans), compressor air for Weld cables, Water cooling for clamp Welding cable lengthe: 7.2(2.2m)stand Max weld thick on sheets(mm) 4+4 or 2+2+2 Insulationm class: H Pretection degree: IP22 Product package of Inverter spot welding system V6: Net Weights: 165KG Gross Weights: 200KG Dimensions(MM): 1390*740*630 Quantity for 20'GP: 40PCS Quantity for 40'GP: 84PCS Quantity for 40'HQ: 105PCS
