First get to know the power supply voltage and allow the power plug, and then according to the welding voltage under the corresponding input combination method to adjust the input terminals, to check whether the electric welding machine output is in the state of connection, you need to check whether electric welding machine enclosure grounding wire connected and the inspection is completed more than to use the power supply is connected.
Connect the power, turn on the switch, clamp the electrode, adjust the current, start work. The most basic is to protect the eyes, hands and feet, generally does not serious injury, resistance welding, electroslag welding, automatic welding, the eyes have to protect good, complete protection to, masks, gloves, clothing. With good, the ground at the time of welding current to the right.
