1090 WIRE SPEED
Wire Speed listed is a starting value only − Wire Speed setting can be fine−tuned while welding. Wire Speed also depends on other variables, such as stick out, travel speed, weld angle, cleaniness of metal, etc.
Input Line Voltage
Higher e.g. 240 Volts AC
230 Volts AC
Lower e.g. 218 Volts AC
