Product Description:1. Using inverter technology, IGBT dual module to save energy.
2. Reactors and transformers are all copper wire wound.
3. The actual input current ensures compliance with the described current value.
4. Small size, light weight, high reliability, good welding effect.
5. All products are available for OEM.
6.Guaranty: One year for the whole machine and PC board, and we will offer you spares valued 4% of the total amount for you to do maintenance.
Features:
1.Adopt the soft switch technology, high efficiency, low power consumption
2.Automatic protection from overcurrent, overheat, over/under voltage
3.Support DC TIG welding, pulse TIG welding and MMA welding, can weld such metals as stainless steel, alloy steel, copper, silver, titanium, etc.
4. In TIG welding, can select DC or pulse welding according to the requirements, can adjust the peak/bottom current, pulse duty circle and frequency according to the size of welding seam
5. In TIG welding, HF automatically strikes arc, and extinguish automatically after the arc is successfully stroke, high efficiency
6. With the long/short seam switch and gas/water cooling switch, can make selection according to the actual need
7.In MMA welding, suitable for the electrode with a diameter of below 5.8mm
8.Can realize TIG grounding and MMA covering once a time, high efficiency, especially suitable for the welding of thin rare-metal board
9.Wide range of supply voltage, as wide as ±20%
