Best single phase tig welder Buying guide
When choosing a single-phase TIG welder, consider the amperage range, duty cycle, and type of welding you will be doing.
Amperage range determines the thickness of the metal you can weld. The more amperage, the thicker the metal you can weld. However, it also determines the size of the welder – the greater the amperage, the larger the welder.
Duty cycle is the percentage of time the welder can be operated in a 10-minute period before it needs to cool down. Generally, the higher the duty cycle, the more reliable the welder.
Finally, consider the type of welding you will be doing. If you are doing a lot of aluminum welding, look for a welder that is specifically designed for this type of welding. You will also want to look for a welder that has adjustable current settings so you can fine-tune your welding settings.
When shopping for a single-phase TIG welder, make sure to compare the amperage range, duty cycle, and type of welding you will be doing to ensure you get the best welder for your needs.
