Basic steps of welding operation
1. Basic operation steps
⑴ Step 1: Prepare for welding
Hold the welding wire in your left hand, hold the soldering iron in your right hand, and enter the welding preparation state. The tip of the soldering iron is required to be kept clean, free of oxides such as welding slag, and coated with a layer of solder on the surface.
⑵ Step 2: Heating the weldment
The tip of the soldering iron leans against the junction of the two weldments and heats the entire weldment for about 1 to 2 seconds. For soldering components on printed boards, care should be taken to make the tip of the soldering iron touch both objects to be soldered at the same time. Wires and terminals, component leads and pads should be heated evenly at the same time.
⑶ Step 3: Feed the welding wire
When the welding surface of the weldment is heated to a certain temperature, the solder wire contacts the weldment from the opposite side of the soldering iron.
Note: Do not send solder wire to the tip of the soldering iron!
⑷ Step 4: Remove the welding wire
When the welding wire melts a certain amount, immediately remove the welding wire to the upper left 45°.
⑸ Step 5: Remove the soldering iron
After the solder infiltrates the soldering pad and the soldering part of the weldment, move the soldering iron away from the upper right direction by 45° to end the soldering. From the third step to the end of the fifth step, the time is about 1 to 2s.
