An AC/DC TIG welder is a versatile welding machine that uses tungsten inert gas (TIG) welding to create high-quality welds on a variety of metals. These machines can operate on both alternating current (AC) and direct current (DC), making them suitable for welding materials such as aluminum, stainless steel, and mild steel. The AC function is particularly effective for welding non-ferrous metals, while the DC function is ideal for ferrous metals.
| Input Voltage | 220V to 480V |
| Output Current Range | 10A to 300A |
| Duty Cycle | 20% to 60% |
| Weight | 50 lbs to 150 lbs |
| Cooling Method | Air-cooled or water-cooled |
When choosing an AC/DC TIG welder, consider the types of materials you will be working with and the thickness of those materials. Look for machines with adjustable output current for better control. It's also important to check the duty cycle to ensure it meets your production needs. Specify any required certifications or features such as pulse welding capability or advanced control options when requesting a quote.

AC is used for aluminum and magnesium, while DC is best for steel and other ferrous metals.
Typical machines can weld materials ranging from 0.020 inches to over 1 inch thick, depending on the machine's output.
Yes, standard safety gear includes welding helmets, gloves, and protective clothing.
No, TIG and MIG welding require different equipment and processes.
Most machines have a duty cycle between 20% to 60%, indicating how long they can operate before needing a cooldown.
While not mandatory, a foot pedal allows for better control of the welding current.
