MIG Welder Buying Guide

The MIG in MIG welding means “Metal Inert Gas.” It is the arc welding process wherein continuous solid electrode wire is fed with a use of a welding gun to the weld pool, thus binding two materials as one. Inside the welding gun is a shielding gas mix along with the solid electrode wire and acts as a contamination protection for the weld pool. This is important because the weld must be shielded from oxidation.

Advantages and Disadvantages

Switching from regular stick welding to MIG welding may seem simple, but knowing the advantages and disadvantages will greatly help in knowing whether to buy an MIG welder is advisable. Here are some common Pros and Cons when it comes to MIG welding.

  1. Advantages – the main advantage of using welding machines that use flux core is portability. This is mainly because no bulky gas cylinders lug around with the welder. Such flux core machines that feature direct current shielding leads to deeper permeation perfect for overhead and perpendicular welds leading to a stress-free welding process. In addition, in MIG welding, no fillers or metal waste is produced. In general, thinner materials are welded together much easier compared to regular stick welding. Another reason why many prefer MIG welding is that it is a welding process that produces neat welds, and chipping slag is not required.
  1. Disadvantages – some cons with flux core wire are excessive smoke, slag and splatter, the price of flux core, and difficulties in thin metal use. Switching to MIG welding certainly will lead to high initial cost, added with the need to purchase a shielding gas regulator. Some machines though can be used with flux core that protects themselves with no need for gas or regulator. All material types can be welded by the MIG welding machine, but the process for different materials does require various wires and gas making it quite complicated.

Choosing the Best MIG Welder

A good number of MIG welder models from different manufacturers are available for the choosing. Offering a wide array of features, additional accessories, and of course, prices makes choosing the correct welder challenging. This is why it is important to do proper research and comparison before purchasing one. The best MIG welders available today have been discussed already, so we will now focus on the important specs that are worth considering and would help in selecting the right and best value MIG welder. The following are some important specifications that make an MIG welder a good performer.

  1. Input Power – most welders run either on 110 Volts or 220 Volts, but many units feature dual voltage option. This makes such units more flexible and highly favorable. It is important to understand though that higher voltage means more power is needed to operate the machine. Therefore, for home projects or thin metal works, lower voltage welders are more appropriate. If welding projects involve thicker sheets, a welder with a 220 volt input power is recommended.
  1. Duty Cycle – the duty cycle of a welder is measured in between 10-minute increments. This is the number of minutes the welder can continuously run within the 10 minute time period. This means that a welding machine that has a 40% duty cycle weld for about 4 minutes before the welding machine needs a rest. So a machine with a high duty cycle will have longer welding time in any 10-minute period.
  1. Heat Overload Protection – this feature is not present in all MIG welders available today, but it’s certainly very important if one values safety in the workplace or home. This feature makes sure that the welding machine automatically shuts off when its temperature gets too high. It’s a crucial feature that saves the workspace and the machine itself.
  1. Material Thickness – the effectiveness of any welder depends on its capacity to weld depending on the thickness of the material to be welded. Fortunately, most welders have adjustable settings that will allow power control so that the user can customize the needed power or strength that would work best for the work at hand. Some even feature digital displays, making it simple to adjust to the right levels of power. It is advisable though to check the machine’s maximum and minimum power and also its limits in thickness of materials to be welded. Under power machines would get you nowhere, and pushing your machine to its limits may cause breakdowns.
  1. Portability – aside from its superb performance, it is always advisable to pick the best portable MIG welder It doesn’t matter if the welding machine is for DIY home use or for heavy industrial use, a portable welder would be perfect in maneuvering around in any workplace. It is ideal for the on the go welder, but not a big issue if you plan to keep and work with it in a permanent location like the garage. The perfect portable MIG welder is light but still packs a punch when it comes to welding capabilities.
