New hardware platform
1. Abandon the obsolete industrial frequency transformer solution, adopt the industry-leading three-level main power topology, output frequency up to 180KHz, full soft switching of the power switch tube, and cooperate with the whole digital control scheme of the whole machine to improve the power density of the welding machine Reduce the overall heat generation, reduce the volume of the radiator, and reduce the weight of the whole machine.
2. The leading power conversion solution brings up to 90% power conversion efficiency. The power efficiency is more than 20% higher than the traditional tap machine and about 8% higher than the conventional inverter welding machine.
3. Unique dual-loop motor drive control scheme: inner loop current control, more powerful wire feeding; outer loop speed control, more stable wire feeding. The speed is sampled by the code disk, which directly controls the wire feeding speed, and the wire feeding speed is more accurate.
4. Multiple clean warehouse design, strong and weak electricity are completely isolated, which greatly isolates the PCB from pollution, effectively prevents dust and water, fully prolongs the life of the whole machine, and is more secure and reliable. The protection level reaches the industry-leading IP23S.
5. Full-package intensive integrated air duct, stepless speed regulation of DC fan, greatly improving heat dissipation efficiency, reducing fan loss and extending fan life.
New control scheme
1. Dual control loop power supply, ultra-high control frequency, full software adjustment, can accurately control the transition state of each droplet, and calmly meet the needs of each welding process.
2. The slope of current change is as high as 1500 amps / msec. The welding wire is concentrated in the wave-controlled high current area, the arc is stable, the anti-interference ability is strong, and the arc can quickly restore stability when the welding is abnormal.
3. The voltage matching range is wide, which can adapt to the change of dry wire elongation caused by various reasons, which greatly reduces the reliance on the accuracy and stability of the welding gun, wire feeding mechanism, and welding operation methods.
4. Welder's default "fast" mode can be set to "standard" mode, the same welding machine can use two welding processes with completely different characteristics
Dex PM3000 can do what the traditional welding machine can, but not the traditional welding machine
1. High temporary load rate, high deposition rate, high wire feed speed, maximum wire feed speed of 28 m / min. Under the condition of guaranteeing welding forming, the welding walking speed can exceed 2 meters / minute at the maximum.
2. The arc starting is soft and the success rate is high. A molten pool can be quickly formed at the moment of arc starting. A full and round solder joint can be formed in 0.3 seconds.
3. The arc is soft and the bridging ability is strong. We can calmly face the welding gap caused by rough cutting of customers.
4. The arc is concentrated, the direction is clear, the penetration is strong, and the same welding current can obtain a larger welding penetration.
5. Intelligent control of welding energy, energy is concentrated in the melting zone of the welding wire, the deposition rate is high, and the same welding current can support a larger wire feeding speed.
6. Lower arc current, more reasonable welding current waveform control, bring less welding spatter.
Dex PM3000's new pulse process brings a new welding experience and makes pulse welding easier
1. Multi-purpose machine, compatible with Dex CM3000 welding process, carbon steel, stainless steel, aluminum alloy, DC, pulse, double pulse, everything is proficient.
2. Huge expert welding database, unified adjustment and automatic parameter correlation make it easier to obtain satisfactory welding results.
3. New pulse welding control scheme, softer arc starting, more stable welding and lower welding spatter.
4. Strict energy distribution for welding scheme, double-pulse forming is more clear, and stainless steel can also weld clear fish scales.
5. A variety of aluminum welding expert systems and special procedures ensure the best welding quality of various aluminum materials.
6. The parameters of each stage of open pulse welding can be fine-tuned according to different working conditions to obtain better welding quality.
