Using steps:
Firstly, check the electrode and welding-needle of the machine, and the two electrodes can not contact each other. (if contact accidentally, don't worry, it will not damage the machine)
Secondly, turn on the power switch, the power light will light up, and the machine will be entered into standby state, standby power consumption is 2W.
Then, after entering the power-on state, adjust the current and time parameters according to the thickness of the weldment. The current is generally adjust to 80-100, and time is generally adjust to 0-10.
The power situation is different in different regions, and the actual operation is generally adjusted from low to high, and welding firmly!
Finally, place the nickel sheet flat against the battery, press the two soldering pens on the nickel sheet, adjust the current and time, step on the foot pedal and the work light flashes to complete the welding!

Parameter analysis:
Current: refers to the size of the welding output power, the value is converted, the minimum output.
Time: refers to the length of the energization time during the welding process, numerical simulation, the longer the energization time.
