1. First, get ready. Now turn on argon and turn on the switch of the welding machine.
2. Adjust the current of the welding machine to a reasonable range according to the thickness and material of the plate to be welded.
3, need to use protective glasses when welding, to prevent eye burns, but also to prevent flying sparks from burning themselves.
4. Fix the materials to be welded by spot welding, so that the remaining welding is more convenient.
5. When welding, it is necessary to hold the welding torch in one hand and feed the wire slowly in the other hand to ensure uniform wire feeding.
6, can form a continuous red line, make the weld more perfect.
7. The final welded gap is more perfect and beautiful.
The principle of electric welding:
Electric welding is to reduce the voltage and enhance the current of the commonly used industrial power supply of 220V or 380V through the voltage reducer in the electric welding machine, and to melt the steel by using the huge heat generated by electric energy. The integration of coated covered electrode makes the bond between steel higher. When welding, the electrode, as an electrode, on the one hand plays the role of conducting current and initiating arc, so that a continuous and stable arc is generated between the electrode and the base metal, providing necessary heat for melting welding. On the other hand, covered electrode, as a filler metal, is added to the weld and becomes the main component of the weld metal.
Precautions:
Beginners often have hand tremors when welding, which is caused by mental stress. The more I want to weld well, the more nervous I am. As the learning time becomes longer and the technology becomes better, it disappears. There are still some people who lack arm strength and can strengthen their exercise. They can take a covered electrode with a cover and tie it to a load for training, or they can use a head-mounted welding cap and hold the welding handle with both hands.
