How to Setup a MIG Welder

Setting up a MIG welder may seem like a big job at first, but once you get to know the controls and how they operate, it will be a breeze. It is important to practice proper safety around a welder, as the gas and heat can be extremely dangerous if not used properly. These steps will help you set up a MIG welder.

Difficulty: Moderate

Instructions

1. Understand the number of controls and what they do. There are a total of three power controls to the MIG welder that you will need to operate depending on the weld, metal and project you are working on.

2. Choose the setting on the first control. It will be all the way to the left and is similar to a toggle switch. The setting on the top is "minimum," the setting on the bottom is "maximum" and the middle setting is "off." The minimum and maximum settings indicate the power level. The minimum should be used for thinner metal.

3. Study the next switch, which will have a "1" on top and a "2" on bottom. These numbers indicate the power output. Number one is lowest power output, while two is the highest power output.

4. Use the dial control to control how fast the wire is pushed through the nozzle and essentially how fast you weld. The dial contains numbers 1 through 10. This process is learned by trial and error, it is hard to know what speed you need unless you are familiar with welding.

5. Set the gas pressure valve to the setting you want for the particular project you are doing. This is the last control you need to worry about before you start. Remember, you must connect the weld tip to the work piece to complete the electrical circuit for the weld to work.
