MIG welders are perhaps one of the most popular types of welders on the market. These welders make it simple to tackle tough metal welding projects and make the process of applying a weld a more streamlined and simplified thing. However, the quality of the welder has a lot to do with the quality of the welding action. Because welders can be a little more on the costly side than some other forms of equipment, you may be considering buying a used MIG welder for your construction business. Here is a short list of things you should be looking for when buying a used MIG welder. 

Make sure the exterior casing of the welder is not beat up. 

It is going to be difficult to find a used welder that does not have some bumps and scratches on the exterior casing of the main unit. After all, these MIG welders get packed to all kinds of places to do all kinds of tasks. However, you definitely don't want a welder that looks like it has been through a hurricane. If the exterior casing of the welder is severely damaged, it is a good sign that the current owner did not take good care of the unit. Be especially mindful of things like rust and corrosion, which would signify the welder has been left out in the weather. 

Make sure the electrode feeder is in good operable condition. 

The reason people like MIGs is the fact that they utilize a feeder for the electrode material instead of rods, which can give a more continuous weld. Therefore, buying a MIG that has major electrode feeder problems is generally not a good idea. Some MIG welder models do have feeders that are fairly easy to replace, but still, this is one of the more expensive parts to replace. 

Make sure the welder has no electrical issues internally or externally. 

If you are buying an electric-powered MIG welder, the biggest thing you need to be checking for when buying used is that there are no problems with electrical power supplication. Electrical problems tend to be one of the most common reasons these welders quit working. It could be something small, like a frayed wire or loose connection, but oftentimes, electrical issues point to major internal problems that would be really hard to fix without an almost complete rebuild or the inner-working parts and components.
