• Comprehensive protecting function: with the protection of overvoltage, under voltage, default phase, against lightning stroke, overcurrent, over heat etc.
• The unique air duct design: failure rate greatly reduced, extending the service life of the machine.
• Unitization design: the machine consists of 4 units-control unit, input unit, inverter unit, output unit. Only need replace the related unit power board for maintenance, any professional debugging is unnecessary.
• Designed for heavy duty stick welding needs. Whether you are using cellulose, low hydrogen, stainless steel or hardfacing electrode, it can produce a smooth, quality arc for consistent results day-in and day-out.
• Easy to operate-Microprocessor panel control makes procedure setting simple and easy.
• Arc gouge with the carbon electrode.
