TIG Welders
- Provides the highest quality, precise welds
- Highly aesthetic weld beads
- Allows adjustment of heat input and torch while welding by use of a foot control
- Has shielding gas
- Uses both AC and DC
MIG Welders
- The easiest to learn
- High welding speeds
- Better control on thinner metals
- Cleaner welds possible with no slag to clean
- The same equipment can be used for Flux-Cored Welding
- Has shielding gas
- Using filler metal
Stick Welders
- Better suited for windy, outdoor conditions
- More forgiving when welding on dirty or rusty metal

Types of Projects and Corresponded Metal Thickness
Next, identify the types of welding projects and materials you will weld most of the time.
Are you a professional welder or just a hobbyist? Do you want to create metal works or simply fix broken metal materials or attach metal pieces to each other?
Based on the types of work you want to do with welders, refer to the information below to know what kind of welding machine you should choose.
| Possible Projects | Average Material Thickness |
| Auto body | 3/16-inch or less |
| Trailer frames and fencing | 1/4-inch to 5/16-inch |
