In the MIG welding process, a steel wire or electrode is fed through a liner from the welder and out of the machine gun’s contact tip. This power is used by the welder for heating up and melting the wire for being used as an adhesive. Integration of inert gas into the metal liquid prevents it from mixing with other atmospheric substances. You can join two metal pieces as they pass through the welding gun by using the melted electrode under optimal wire control and voltage.
The process of MIG welding is quicker and simpler compared to traditional arc methods which makes it the best choice for novice users. You can bank on this process to weld both thick plates and light-gauge carbon, aluminium and iron. Such attributes make it the best bet for being used during hobby welding, autobody work, fabrication etc.
Today we are going to take you through five of the best MIG welders which have been chosen on the basis of weight, input voltage, metal thickness, duty cycle and many more parameters. But first, we are going to take a look at some of the equipment which can add to the efficiency of your welder.
Equipment Required For Your Welder
Taking good care of the welder can promise you consistently high-quality welds even after prolonged usage. Usually, MIG welders do not have high maintenance requirements.
But you can take some small steps today to make a big difference in the long run. For starters, you can keep the welder covered when not in use. This becomes an absolute necessity while using the welder in a workshop. Dust particles can damage your welder over time.
Usually, welder manufacturers also sell covers tailor-made for specific models. Dirt build-up can also happen on the drive rolls through which the wire is continually fed. You can clear out the dust by blowing some air through them or brushing them down every now and then.
Lastly, comes the contact tips which are highly vulnerable to spatter build-up. This can cause porosity and limit the flow of shielding gas which prevent contamination of the bead. You can coat the tip using a nozzle dip for preventing splatter from sticking on the same.
