In the welding, the electrode touches the part lightly. There is no need to press the electrode against the part. After the electrode touches the welding piece, argon gas flows from the nozzle of the electrode. Argon gas both prevents oxidation of the part due to the oxygen in the air during welding, and also ensures that the welding arc is formed properly. The welding spot takes place one second after the electrode touches the part. When the welding spot occurs, the electrode retracts itself and an arc is formed. After the welding takes place, the electrode returns to its original position. The point to be considered here is not to press the electrode on the part while shooting.
