Factors To Be Considered Before Purchasing An MIG Welder

Multifunction or MIG/Flux-Cored Welders

The MIG welders might either require a gas cylinder or may be flux cored while some have capability of both. Initially the flux core models might seem to be more appealing since the gas cylinder does not require to be hooked up. However, a layer of slag is created by flux core models which require to be chiselled away. For ensuring maximum diversity, it is advisable to opt for welders having both these functions available.

Transportability and Size

The machine needs to be easily portable if you are planning on using the same in multiple locations. The same might not pose as a big threat if you wish to get your job done in a workshop. However, if your power requirements cannot be encompassed within a portable size, then you can place the same on a wheeled cart for being moved around. High quality MIG welders weigh a minimum of 25 pounds and come with inverter technology which aids in bringing down its weight while the heavier options can weigh anywhere around 200 pounds.

Output Power

The power requirement varies in accordance with the type of welding you are trying to achieve. Several manufacturers provide with a custom chart which can be of great yield in choosing the correct settings and benefitting from the highest quality weld.

Spool Gun

If you wish to weld aluminium, then it is essential to purchase a welder capable of attaching a spool gun which is not the case in most of the smaller sized versions. You can take the example of Hobart 140 which in spite of being a brilliant welder does not include this functionality like that of the Longevity 140. While purchasing a spool gun it is recommended to go ahead with one having quick release feature.

Brand & Warranty

It is always advisable to proceed with a trustworthy and reliable welder brand. Various welder manufacturers bring along different support levels but Hobart, Miller, Lincoln and Everlast are some top-notch brands which have been delivering quality products for quite some time now. Also, make sure to check your welder’s warranty which usually extends up to 5 years in top models and provides extra investment assurance. If you wish to try out lesser known brands, then make sure to conduct a thorough market survey before purchasing the same.

Duty Cycle

The length of welding time can also be a determining factor especially if you require using the MIG welder for long stretches. Welders having higher output power and lower duty cycle require increased span of time for cooling down. If you are worried about the machine being overheated, then you should purchase a welder having thermal overload protection thus preventing damage to the welder by keeping the duty cycle from getting exceeded.


Last but not the least, budget also plays the role of a determining factor while bringing home a MIG welder. Contrary to popular belief, the most expensive one might not suit you best at all times. If you know exactly what you are looking for given the specific budget, then you can pick the optimum welder to usher in finest performance at diminished expense.
