Both MIG and stick welding fall into the overarching category of “arc welding”. What arc welding means is that MIG welding and stick welding utilize electricity as their heat source. This heat source is then transformed to join together pieces of metal.
MIG welding (metal inert gas) is mostly utilized for smaller and more delicate welding projects. This includes standard projects around the house, minor repair jobs, and smaller shop-related work. Stick welding, on the other hand, is far more useful for larger projects, including structural welds, pipeline welding, and reactors. While MIG welding is suitable for beginners, stick welding requires high levels of skill and a steady, well-trained hand.
But the differences don’t stop there. This article will compare stick welders and MIG welders. We at Tool Guides Hub aim to highlight some of the major differences that exist between these two types of welding machines. Some of the differences highlighted in this comparison piece include: Levels of weld penetration, margins of error, operational costs, safety when welding, and quality of welds.
Comparison of MIG Welders vs Stick Welders: Error Margins
MIG welders offer great opportunities for its users to customize settings in many different ways. For instance, users will need to adjust the voltage, electrode, grounding, torch angle, technique used, and gas flow. What this means is that MIG welding relies heavily on the skill of the user compared to stick welding. For this reason, the margins of error involved in this facet of arc welding is much higher than the margins of error that would occur in stick welding.
It is also worth noting that, due to the fact that the adjustments and modifications are not necessary with stick welding, it might not be the most suitable for structural welding. Comparing MIG welders and stick welders regarding error margins shows that stick welders are far better than MIG welders in this category.
Penetration Levels in Welders
When mentioning levels of penetration, what is meant is the way that the welder penetrates the weld joint. As far as penetration level is concerned, stick welders beat out MIG welders for multiple reasons.
For starters, stick welders do not require much effort for weld penetration. As long as the electrode is lit, there is little effort needed. Additionally, proper positioning techniques during the welding processes add an advantage for stick welders. With this, penetration weld joins make penetration far more simple. Also, adjusting amperage to the correct settings guarantees stronger join penetration for stick welders compared to MIG welders. This is simply not the case with MIG welders.
Operating Costs of MIG Welders vs Stick Welders
Comparing operational costs of MIG welders and stick welders shows a strong difference between the two types. While MIG welders require some prerequisites such as shielding gases, stick welders are good to go with minimal preparations necessary. Additionally, by comparing MIG welders vs stick welders by number of moving parts involved, it is clear to see that MIG welders have many moving pieces, increasing associated operating costs.
Also, MIG welders require a good bit of preparation before use. Alternatively, stick welders do not require this, as they are limited in potential problems that might arise in the process. These potential problems are what lead to higher operational costs and necessary repairs.
Safety and Quality of MIG Welders vs Stick Welders
When comparing potential safety concerns of MIG welders and stick welders, the jury is still out on which edges out the other. This is because both welding machines require a very high amount of concentrated heat to work properly. Additionally, there are sparks that emanate and molten metal spattered out in the process. It is vital to have proper gear to be safe from the effects of the metal spatter. However, the inclusion of shielding cases in MIG welding requires additional caution when storing both during and after usage.
It is incredibly important to ensure that the environment of the welding area is void of potentially explosive and flammable materials. Regarding quality, both MIG and stick welders produce insanely high quality welds. MIG welders work better with thinner metals such as aluminum, while stick welders produce higher quality welds in thicker metals. This is due to the stick welders’ solid joint penetration mentioned above. It is also worth nothing that with the correct choice of electrode, proper technique, and correct settings, welders are good to go. They will experience strong quality, regardless of the type of welder being used.
