Factors to Consider When Choosing a MIG Welder

MIG welders are a great choice for both DIY home projects and industry-grade tasks. To find the best MIG unit, however, some various concepts and factors must be taken into consideration, some of which are listed below:

  1. Motor Amperage

This refers to the electrical current load of the welder’s motor for a given period of time. The motor amperage of a MIG welder determines the size (thickness) of material that the unit can weld for a period of time without affecting the various components of the motor. For example, you will require a motor amperage of 180 amps to weld into a quarter-inch of steel in a single pass. Ensure that you evaluate this factor before purchasing a MIG welder. Also, look into reliable online resources to determine the needed amperage for various metal types and thickness.

  1. Percentage Duty Cycle

Duty cycle refers to the timing ratio when a welding unit is on and when it is off, and it is typically expressed in percentage. The duty cycle of a unit influences the duration that you can use it continuously. The higher the percentage duty cycle, the more reliable the machine. A welder with a 40% duty cycle, for example, means that the unit must be out of use for 6 minutes after 4 minutes of using it. For larger projects, you might want a unit with a relatively high percentage cycle for efficiency.

  1. Gas or No-Gas Modes

While some MIG welders require gas to operate, some do not, as gas is not a fundamental component for MIG welding. For DIY and irregular welders, a gasless welder would be ideal. Gasless units are more portable, save you money, and minimal clean-up is required after use. Alternatively, you might need a machine that uses gas for high-quality welding. Consider a model that allows you to upgrade from the gasless to hand gas modes.

  1. Thermal Overload Protection

There are plenty of security features that you must consider when buying a MIG welder, and thermal overload protection must be on the list. The thermal overload protection feature initiates an automatic shut off of the welder to prevent possible damages. This feature is activated when there is airflow restriction and when the percentage duty cycle has been hit.

  1. Portability

Portability is an essential factor, especially when you do not have a designated location for your MIG welder. Having a lightweight welder will be helpful if you have to work from an outdoor space. However, if your machine will not have to be moved from one place to another when you need to work, then you can always opt for a heavier and sturdier welder.

  1. Complementary Accessories

Accessories go a long way in easing out the welding experience. If you are a first-time buyer, then you might want to look for a MIG welder with an assortment of complementary accessories. A basic package of accessories should include such tools as fastening clamps, a torch, cleaning materials, and protective gear. You can always get more specialist accessories, such as eye protection gear and some pairs of gloves.
