Product type
A TIG welding machine is a type of welding equipment that uses a non-consumable tungsten electrode to produce the weld. The process involves feeding a filler material into the weld pool while an inert gas, usually argon, protects the weld from contamination. TIG welding is known for its precision and ability to weld thin materials, making it a preferred choice for applications requiring high-quality finishes.
| Input Voltage | Single-phase 120V or 240V, three-phase 380V or higher |
| Welding Current Range | 5A to 300A |
| Duty Cycle | 20% to 100% at rated current |
| Weight | 20 lbs to 100 lbs |
| Control Type | Analog or digital control |
| Cooling Method | Air-cooled or water-cooled |
When choosing a TIG welding machine, consider the input voltage and welding current range to ensure compatibility with your power supply and the materials you will be working with. Look for machines with a suitable duty cycle for your application, especially if you plan on using it for extended periods. Additionally, consider whether you need air-cooled or water-cooled options based on your working environment and project requirements. Specify any necessary certifications or features such as high-frequency start or pulse welding capabilities when requesting a quote.

TIG welding is suitable for welding stainless steel, aluminum, copper, and other non-ferrous metals.
TIG welding uses a non-consumable electrode and is better for precision work, while MIG welding uses a consumable wire and is faster for thicker materials.
Yes, TIG welding requires an inert gas supply, typically argon, to protect the weld area from contamination.
TIG welding can effectively join materials as thin as 0.005 inches to several inches thick, depending on the machine's specifications.
TIG welding requires more skill and practice compared to other welding methods, making it more challenging for beginners.
Essential safety gear includes a welding helmet, gloves, protective clothing, and proper ventilation.
