What can be the consequence of using a torch tip that is too large?

Using a torch tip that is too large can indeed burn holes in the metal. This occurs because a larger flame has a broader heat area and can easily exceed the melting point of the material being welded. When the heat is concentrated excessively on a specific area due to the larger torch tip, it can vaporize the metal instead of allowing it to melt and fuse properly, leading to holes or excessive penetration.

Moreover, the larger flame can also make it more challenging to control the heat effectively, resulting in a lack of precision that is essential when welding thin materials. Consequently, careful selection of the correct torch tip size is crucial for achieving the desired weld quality and structural integrity.
