This device is a dual-manual welding TIG welder. ? 8 major characteristics of a welder Andre. IGBT tube using imported more than 10,000 hours of service life, MOS tube IGBT even older than the domestic section of the pipe, under the same conditions IGBT tube imports higher efficiency, longer life, more stable. Traditional MOS because structural problems, low pressure, consistency is not high, will be prone to the phenomenon of the bombing. II. The use of high-quality capacitors outwit + Jinyuan, at 85 ℃ operating temperature can still continue to work 2000 hours at full load without drastic attenuation. Capacitance tolerance ± 10%, far less than the national standard ± 20%. III. Transformers using amorphous structure custom models, compared to a generation inverter main transformer core, core reduces heat generation, under the same operating conditions can select more compact core, meet welding industry lightweight, small development requirements. Under the same core size, the same volume of second-generation core performance compared with the generation of the core can be increased by about 10% -25% IV. SMT high density panels, Andre proprietary chip technology in the 21st century, more stable, more durable and more efficient. Surface mounted to a printed circuit board (PCB) by mechanical precision to a short pin leadless or surface mount device (chip components). Reduce staff turnover rate caused by the operation, process improvements, the circuit is more compact and beautiful; higher seismic capacity, lower solder defect rate, good high-frequency characteristics, to reduce electromagnetic interference. Five. Patented heat sink design wavy folded surface structure, increase the cooling effect than conventional MOS pipe welding efficiency more than 20%, welding industry in the most "weight" of the radiator, the total weight of 200 welder 862.1g, materials about 45 percent higher than the average traditional welding. VI. Technology paragraph 7 high performance leaf blower, 3800 rev / min, rectifies the AC AC220V DC24V safe voltage, electric shock! When the foreign object stuck in the fan, to achieve automatic power-off protection to prevent overheating damage welder, troubleshooting automatically reset. Seven. Upgrade ceramic armor, with a tortoise imported IGBT tube dual voltage performance of achievement. Layer PCB board, 100% PCB new material, smooth and translucent plate quality good insulation effect, thickness of 1.6mm; bidirectional copper traces, more optimized circuit currents go faster.
