| Name: DC spot welder - phase rectifier 3 * 100KVA model: JDTZ-3 * 60/3 * 100/3 * 150/3 * 200KVA Applications: In addition to welding mild steel, coated steel, stainless steel, heat-resistant alloys, copper, aluminum and aluminum alloy, but also can be welded titanium, niobium, zirconium, tantalum and other rare metals and multilayer plate. Features: | 1. This type of welder is at the output of the transformer secondary winding solder power added silicon diodes, the alternating current into direct current for welding new better weldability. | 2. The secondary DC circuit inductance can be ignored | | When the same output current, welder power factor greatly improved, up to 0.8-0.9. This welder required apparent power only ordinary welder 1 / 3-1 / 5, greatly reduce the impact on the grid. | | | | 3. DC heating | | No time alternating magnetic poles arm, to avoid splashing, cluster effects of the direct current generated by the ferromagnetic metal AC amplitude of the current is too large to produce good solder joints shape, penetration, multi-layer steel spot welding but also to ensure quality. | | Technical Parameters: | | | | unit | Rated | Rated | Rated | load | Arm extension | Maximum pressure force | electrode | cool down | weight | Welding capacity (two stitch welding) | | | model | capacity | Voltage | frequency | Sustained rate | size | | stroke | Water | | | | | | | KVA | V | HZ | % | mm | N | mm | L / min | KG | mm | mm | | | JDTZ-3 * 60 | 3*60 | 380 | 50/60 | 50 | 500*300 | 15000 | 20-80 | 30 | 1000 | 5.5+5.5 | 3.0+3.0 | | | JDTZ-3 * 150 | 3*150 | 380 | 50/60 | 50 | 400*350 | 24000 | 40-120 | 50 | 1600 | 6.5+6.5 | 4.0+4.0 | | | JDTZ-3 * 200 | 3*200 | 380 | 50/60 | 50 | 400*350 | 30000 | 40-120 | 80 | 2000 | 7.0+7.0 | 4.5+4.5 | | | |
