A fair market price for 2025 ranges between £900 and £3,500, depending on brand and specifications.

Investing in an AC/DC TIG welder supports varied applications, such as automotive fabrication or aerospace components, reinforcing its value among professionals seeking equipment optimised for detailed and robust projects.

Key Features To Consider

When selecting an AC/DC TIG welder, several critical factors influence performance and usability. Highlighting these features ensures informed choices for welding tasks across industries.

Power Output And Range

The power output determines the materials and thicknesses a welder can handle. AC/DC TIG welders typically provide an amperage range between 5 and 300 amps, offering flexibility for thin aluminium sheets or thick steel plates. For professional use, such as in automotive or aerospace sectors, models with a variety of settings, like the WeldMax Pro 300, are ideal. Higher power ranges also allow smoother transitions between AC and DC modes for complex projects.

Duty Cycle

The duty cycle impacts how long a welder operates continuously before cooling down. A 60% duty cycle at 200 amps means six minutes of welding for every ten-minute interval. For intensive applications, such as automotive fabrication, a higher duty cycle ensures efficiency and uptime. Brands like BritArc 250 are known for maintaining reliable duty cycles even at maximum settings, making them a strong choice in 2025.

Portability And Build Quality

Portable TIG welders combine lightweight designs with durable components. Units weighing 10-15 kg use inverter technology for easier transport and reduced energy consumption. High-quality materials, like aluminium casings, ensure durability under heavy use. Models from UK-based Advanced Weld Systems offer rugged construction, making them suitable for construction sites or workshops. Portability becomes especially important for professionals frequently changing locations.
