How to adjust the current of gas shielded welding machine?

1. Adjust the current knob to the minimum and the voltage knob to the maximum, and try welding. At this time, do not move the voltage knob, and gradually increase the current until it can be welded normally.

2. On the contrary, first adjust the current knob to the maximum, then adjust the voltage knob to the minimum, try welding, don't move the current knob, and gradually increase the voltage until it can be welded normally; At this time, you should feel the respective functions of current and voltage;

3. Adjust the current and voltage knobs to the minimum, and gradually increase the voltage and current (which need to be adjusted repeatedly in the process) until you find a match that you think has the best weld formation, the softest sound and can control yourself. At this time, we can find a way. Current and voltage corresponding to various welding positions, such as vertical welding, flat welding, horizontal welding and overhead welding, can be adjusted.

Matters needing attention in using gas shielded welding machine:

1, welding may cause fire or explosion, and protect yourself and others from sparks and weldments when welding; Welding shall not be carried out where there are combustible substances, because splashing sparks are easy to cause combustion and fire;

2. Smoke and gas generated by welding will harm health; Keep good ventilation during indoor welding;

3, heating parts will cause serious burns, do not touch the heating parts directly with your hands; After cooling, the welding gun can be used for welding.
