2. Water-break, electric-break, automatic stop protection function
3. No engine valve automatic stop function
4. Brush gun regularly function
5. Arc light protection function
6. All the machinery moving parts(except feeder and discharge part) use whole sealing protection measure
4. Install requirement
Below preparation should be ready before machine arriving:
1. Electric powder supply:380VAC±10%,one 65A air switch
2. Gas supply: Bottle industry pure argon purity is99.99%. Provide oxygen pressure reducing valve in the same time.(low tension range 0-4Kg/cm2)
3. Provide 50kg of deionized water.
