Mild Steel,Aluminum,Stainless Steel and other metals wire are capable Input Voltage Compensation keeps welding parameters constant even when input voltage change±15%. Lowest input voltage can be 300 Volts and highest one can be 470 Volts Protections including over-heat,over-voltage,low-voltage and over-current Digital Voltmeter and Ammeters for easy viewing Adjustable weld stabilizer(high-low inductance)provide the flexibility to produce the optimal arc characteristics. Presettable welding voltage and current allows you to easily set weld output before welding Power efficiency gives exceptional value and return on you investment. Stick Function with adjustable Arc force Flux cored self-shielded Cylinder reck ready makes you move completely and set easily
