Model NO.: WSE-400
Trademark: MORROW
Origin: China
HS Code: 8515390000
Model NO.: WSE-400
Trademark: MORROW
Origin: China
HS Code: 8515390000
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. Automatic protection from ovecurrent, overheat, over/under voltage
2. Support AC/DC square-wave TIG welding, DC TIG welding, MMA welding
3. Small size, light weight, high shift efficiency, energy saving, strong adaptability of the voltage
4. In TIG welding, the up/down slope of welding current can be adjustable, and with the function of pre-gas sending and delay gas sending
5. HF automatically strike arc, and extinguishes automatically after the arc is successfully started
6. In MMA welding, can be used together with almost all kinds of welding electrode with a diameter below 5.0mm
7. While DC TIG welding is adopted, can weld all kinds of stainless steel parts, pressure container and pipeline
8. While AC square-wave welding is adopted, can weld the nonferrous metals like aluminum and aluminum alloy, and so on.
9. Adopt inverter technology twice, pure square-wave output, heat concentrated, strong reverse clearance capability; cleaning frequency and ratio can be adjusted, can easily adjust the result of deoxidation in aluminum welding. The mixing ratio and frequency is preset, can effectively protect the tungsten electrode and prolong its service life.
10. Can be equipped with the distance control box to realize the distance control, simplify the operation.
