Input wiring diagram
After welding machine panel of the power input line equipped with circuit breaker and
grounding line access to the single-phase 220 v power supply (power grid); It is strictly prohibited to 380 v power
supply access welder (380 v power supply which can seriously damage the welder), it is forbidden to the earth wire
connected to the electricity grid, otherwise the consequence is proud
。
Notice: the power supply earth connection is
not zero connection.
