How To Adjust A Mig Welder Settings – The Best Beginner Guide 

Setting the proper mig welder settings is essential to creating a good weld. If the settings are too low, the weld will be weak and may not hold. If the settings are too high, the weld may be too hot and could weaken or even destroy the metal.

In order to get your desired results when carrying out MIG welding in different projects, it is important for you to modify the settings on your welder. There are no ideal universal settings; therefore I have outlined a few rules and general guidelines that will help guide you towards success.

Here we go!

What are the different types of mig welders and how do they work?

Mig welders come in a variety of types and sizes, each with its own unique set of features and capabilities. The three most common types of mig welders are gas metal arc welders (GMAW), flux cored arc welders (FCAW), and shielded metal arc welders (SMAW).

Gas metal arc welders use an electrode that is fed through a welding gun and into the welding puddle. The electrode is made of a metal that melts and becomes part of the weld. Flux cored arc welders also use an electrode, but it is consumable and has a core of flux. The flux helps to protect the weld from contamination. Shielded metal arc welders use an electrode that is shielded by a gas. The gas protects the weld from contamination.

All mig welders use electricity to create an arc between the electrode and the base metal. The arc heats the metal, which melts and joins the two pieces together. Mig welding is a fast, efficient way to weld metal, and it can be used to weld a variety of metals, including aluminum, stainless steel, and mild steel.

How to set up your mig welder for the first time

Before you begin welding, it is important to set up your mig welder properly. Follow these steps to ensure that your mig welder is set up correctly:

1. Read the owner’s manual for your specific model of mig welder. This will help you understand the capabilities and limitations of your machine.

2. Select the right type of electrode. The type of electrode you use will depend on the metal you are welding, the thickness of the metal, and the welding technique you plan to use.

3. Select the right gas. The type of gas you use will also depend on the metal you are welding, the thickness of the metal, and the welding technique you plan to use.

4. Set the power. The power settings on a mig welder are generally expressed in volts and amps. The correct setting will depend on the metal you are welding, the thickness of the metal, and the welding technique you plan to use.

5. Set the wire speed. The wire speed is the rate at which the electrode is fed through the welding gun. The correct setting will depend on the metal you are welding, the thickness of the metal, and the welding technique you plan to use.

6. Set the travel speed. The travel speed is the rate at which you move the welding gun along the seam of the metal. The correct setting will depend on the metal you are welding, the thickness of the metal, and the welding technique you plan to use.

 

How to adjust a MIG welder voltage settings

When using a MIG welder, you want to make sure your electrodes lead the electricity flow from metal into your welding handle. The voltage setting will decide how deep the welding torch penetrates through materials and quality of welds.

You may have noticed that your device is not working properly. This could be because the voltage settings are set incorrectly on it. To fix this issue, turn to page 15 in the user manual of product box and look for an instructive chart or diagram showing you how to adjust these setting accordingly by using a wrench tool with no more than one inch diameter head size.

When you cannot find the perfect voltage setting for your welding project, try increasing or decreasing its power by watching how quickly it heats up. If the heat-affected area melts slowly, increase the energy a little bit and vice versa.

Gradually, you can learn to feel the appropriate power level. You will also become familiar with the minimum and maximum range of the settings. For beginners, you had better set the voltage at the medium point for common use at first. Later, modify it for the perfect welds.

You can consult the parameters in the following table. Feel free to change  a bit to suit your cases better.

Max amperage	90	110	130	150	180
Max thickness for bottom joints	5/64	3/32	1/8	5/32	13/64
Max thickness with V cap	1/8	5/32	9/64	15/64	19/64

How to adjust a MIG welder wire feed speed settings

This setting is for adjusting how fast the MIG welder feeds its wire into the weld joints and managing the amperage to some extent. Its unit is IPM (inches per minute).

High speed can create a burn-through and fast popping sound, whereas low speed causes the wire to burn too slow and forms an unstable arc.

Use the chart below to set the wire speed based on the wire size. For example, if the wire size is 0.23 inches (used for sheet metal), then you need to multiply by 3.5 inches per amp, which is equal to 437.5 ipm

• .023 inch                        Multiply by 3.5 inches per amp
• .030 inch                        Multiply by 2 inches per amp
• .035 inch                        Multiply by 1.6 inches per amp
• .045 inch                        Multiply by 1 inch per amp

How to adjust a MIG welder gas flow rate setting

Last but not least, we have the gas flow rate setting that helps regulate the transfer of gas  to protect the weld area from the contaminants in the air. Gas flow rate setting is regulated in CFM (cubic feet per minute).

Lower gas flow rate settings will allow less gas, which is not enough to shield the weld area. The result is the  porosity in the surface of the weld.

The setting should not be too high or too low as higher gas flow may result in  turbulence and weld contamination. Make sure to do some tests to determine the perfect gas flow rate before going on with the real job.

Try to set proper MIG welding settings for mild steel along with other kinds of metals.

The optimal gas pressure varies a little, but it should be around 15-25 CFH.
