If you are not a professional welder and plan to acquire a MIG welding machine then you should consider certain technical factors during your market survey. However, if you are looking for the most suitable welding device in terms of price and functionality then comprehensive research is required. On the other hand, it’s not easy to find the quality MIG welders for ½ steel as there are several options for the latest technology welders available in the market. Somehow, we have managed to review some top-of-the-line welding machines to facilitate your online research over the best MIG welder for ½ steel.

Important factors that should be considered while selecting a suitable welder

Input Voltage

The first factor that should be taken into account is the power input that your welder produces, many welding machines have different input voltages so it is very important to verify that the welder you are acquiring is compatible with the electrical outlet of your workplace. Usually, welders with an input power of 110 to 140 volts can be employed for domestic purposes as household outlets run at this range.

However, if you intend to get a welder for professional projects and if you want to execute some powerful welds then you should opt for a welder that runs on 220 volts of a power outlet. These types of heavy welders are mostly employed for industrial welding where the electrical outlet powers heavy electrical machinery which is compatible with 220 volts of power input.

Duty Cycle

The duty cycle illustrates the efficiency of your machine, like how long you can run the machine safely without posing any damage to the welder. The duty cycle is determined to optimize the lifespan of the welding machine at certain power input. It is usually denoted as a percentage; the percentage is calculated by operating the welder for a 10-minute period before it starts overheating. For instance, if a welder shows a 50% duty cycle it means that it could be operated for 5 minutes and it will require 5 minutes to cool down again.

Commonly, welders with higher output power have lower duty cycle as it would take a longer cool-down period. It is also important to get a welder with a functional cooling system. Welders that come with integrated thermal overload protection technology should be preferred that increases the duty cycle of the welding machine.

Thickness of Metals/ Material Thickness

Metal inert gas welding machines can weld metal sheets of several thicknesses ranging from a 24-gauge (0.0239 inches) or 18-gauge (0.0478 inches) materials to thicker metal paraphernalia of about 3/8 inch or ½ inch deep. Choose your welding machine according to the thickness of the material and future proof it by choosing a welder that can weld metals with various densities.

During the welding process, a shielding gas is emitted which would increase the overall temperature ultimately melting and fusing the two metals.
