Why is Mig Welder Popping?
Mig welding is a process that is used to join metals together by melting them together. It is a popular choice among metalworkers due to its ease of use and affordability. However, one of the most common problems many Mig welders face is the “popping” sound it makes while welding. This sound can indicate a variety of issues that need to be addressed in order to improve the welding process. In this article, we will discuss why Mig welders pop and what to do about it.
What Causes a Mig Welder to Pop?
The popping sound is caused by a combination of several factors. First, it can be caused by the arc that forms when the metal is melted. This arc generates an intense heat that can cause the metal to expand and contract rapidly. This rapid expansion and contraction produces the popping sound.
Another potential cause of the popping sound is the shielding gas used in the welding process. When the shielding gas escapes from the welding area, it can cause a pressure difference between the inside and outside of the welding area. This pressure difference can cause the metal to expand and contract rapidly, resulting in the popping sound.
Finally, a third cause of the popping sound can be due to improper welding technique. If the welder is not moving the welding gun at the correct speed, or if the gun is not pointed in the right direction, it can cause the metal to expand and contract rapidly.
How to Prevent Mig Welder Popping
The first step in preventing Mig welder popping is to ensure that the welding technique is correct. The welder should be moving the welding gun at the correct speed and should be pointing it in the right direction. Additionally, the welder should be sure to keep the welding area clean, free of debris and other objects that could interfere with the welding process.
The second step is to ensure that the correct shielding gas is being used. Different types of shielding gas are available, and the type used should be matched to the type of welding being done. Using the wrong type of shielding gas can cause the metal to expand and contract rapidly, resulting in the popping sound.
Finally, the third step is to check the voltage and amperage settings on the welder. These settings should be set according to the welding specifications. If the settings are too high or too low, this can cause the metal to expand and contract rapidly, resulting in the popping sound.
Mig welding is a popular and affordable way to join metals together. However, it is not without its problems, one of which is the popping sound it can make. This sound is caused by a combination of factors, such as the arc, the shielding gas, and improper welding technique. Fortunately, these issues can be addressed by ensuring the correct welding technique is used, the correct shielding gas is used, and the voltage and amperage settings are correct. By taking these steps, it is possible to reduce the occurrence of popping and improve the overall welding process.
