Product Name: Medium Frequency Spot Welder (25KW/35KW/40KW/60KW/80KW) Model NO.: MF25/35/40/60/80 Type: Spot Welders Current: Alternating Current Application: Ship Model: Spot Trademark: SHELLMAX Transport Package: Standard Export Package Specification: CE CCC ISC9002 Origin: China HS Code: 85152900 Product Description Medium Frequency spot welding system Features:1. Adopt medium frequency inverter controller, current is DC, 1000Hz, high productivity. Small size welding transformer but output power is big. The frequency of transformer can be inceared from 50/60Hz-1000Hz, very save the transformer marterial costs and weight.2. There phase power supply input evenly, it don't affect electric fence, The power factor ≥ 0.95, it won't be leakage the current beacause of increase the electrode arm sets to cause the contact resistance.3. Highly save energy. Lower welding current and pressure of electrode. The electrode life will be longer and more durable, straight away to same the marterials costs and production time.4. High quality. Comparing with traditional welder, the welding stability and concordance are better than others. The speed of controller and current feedback faster 20 times than tranditional frequency welding machine, very few splatter and stable spot point welding.5. Save power more than 1/3 compare with tranditional spot welder. To save theCost for the users.6. Installing the power capicity reduce more than half, reduce the cable cross sectional area to save the installing working time.7. Lower cost. Effective power is more. High productivity. It takes shorter welding time to weld a point than traditional welder.8. Equipped with PLC touch screen, LED display clearly, easy to adjust and operate, The machine itself very save power to bring the long term saving, it's very useful for All of the invest customers in real return.ITEMMF25KWMF35KWMF40KWMF60KWMF80KWRated capacity (KVA)90KW90KWMaximum welding current(KA)25KA35KA40KA60KA80KAMain voltage (V)400V400V400V400V400VFrequency (Hz) 50/60Hz-1000Hz 50/60Hz-1000Hz50/60Hz-1000Hz50/60Hz-1000Hz50/60Hz-1000HzDuty cycle (%) 50% 50% 50% 50% 50%Secondary voltage9.8V11.0V11.6V13.6V14VMaximum force between electrodes(N)4700650072001200018000Throat depth430-450mm430-450mm430-450mm430-450mm430-450mmelectrode stroke(mm)80mm80mm80mm80mm100mmFrequency transformer(Hz) 1000HZ 1000HZ 1000HZ 1000HZ 1000HZRater pressure of pneumatic system (Mpa) 0.6 0.6 0.6 0.6 0.6Cooling water consumption (L/Min)6L/Min6L/Min6L/Min8L/Min8L/Min
