Product Name: T Type Spot Welding Machine Model NO.: DTN-25/40/80/100/150/200/250/300KVA Type: Spot Welders Welding Spot Number: Single Conductive Way: Both-Sided Transmission: Pneumatic Electrode Stroke: Vertical Style: Fixed Cooling Way: Water Cooling Control: Manual Current: Alternating Current Model: Dtn-25/40/80/100/150/200/300 Trademark: xinchang Transport Package: Wooden Case Specification: export standard Origin: Ningbo China Product Description Usage: Be used for Ttype point welding of wire.Method named for welders:Spot(projection) welders series: DTN-P-1(2)-LDTN: Pneumatic AC mains frequency spot(projection) weldersP: Rated capacity1: Lower arm can not be adjustable; 2: Lower arm can be adjustableL: Throat depth, namely arms lengthAdvantage &Feature:1, Machine body of thick steel sheet, not easy to deformation2, Secondary electric conduction parts is style of upper insulation, to avoid short current accident caused by Scrap iron or workpiece.3, The electrodes of speed can be adjusted at random, to decrease strike or workpiece and noise.4, Microcomputer control, accuracy and steady, Can store 15 sets welding schedules, to suit different specification products5, Controller can automatically compensate current, to make welding steady. Some material can be preheat or temper.6, Water cooling transformer: Use silicon sheets of 15000 gauss permeability to pile up. There is cooling water in inside, using full copper alloy core, reducing impedance, improving the utilization of power, 20% duty cycle to ensure the requirement of long time welding, big output power. The useful lifetime is longer, noise is smaller, structure is more compact and reasonable.7, Fast solenoid valve, making welding speed faster, thereby the productivity is higher, therefore decreasing cost.8, Cylinder adopt high accurate, anti-friction hard material, which is duralumin, without rust, lower friction, lower noise and loading is faster, thereby reducing the weld spatter.9, Quality is stable, failure rate is low, therefore machine life is longer Model Unit ItemDTN-25DTN-40DTN-80-1DTN-100-1DTN-150-1DTN-200-1DTN-80-2DTN-100-2DTN-150-2DTN-200-2Rated capacityKVA25408010015020080100150200Primary volts.V380380380380380380380380380380FrequencyHZ50505050505050505050Max short circuit currentKA15182833384328333843Duty cycle%20202020202020202020Max pressureN30003000600060001200012000790079001200012000Operational strokeMM30303030303030303030ElectrodeStrokeMM70707070707070707070Arm length and distanceMM350*220350*220350*250350*250350*270350*270400*300400*300400*300400*300Cooling water fluxL/min3344664466Max weld capacity(steel)MM2+23+34+45+56+66+64+45+56+66+6
