Stable DC arc performance, dual-voltage flexibility, and compact inverter portability for stainless and ferrous fabrication.
TIG-250D combines advanced IGBT inverter technology, DC TIG and MMA dual-process capability, and a compact portable body for stainless steel fabrication, repair work, and general ferrous-metal welding in workshop or field conditions.
Advanced IGBT inverter technology for stable arc output and high efficiency
The IGBT power platform delivers stable welding performance, efficient energy conversion, and dependable output characteristics for daily fabrication and repair work.
DC TIG and MMA functionality combined in one compact machine
Its dual-function design allows users to switch between precision DC TIG welding and manual metal arc welding, improving practical flexibility without moving to a second machine.
Easy arc ignition with concentrated arc energy for cleaner, more precise welding
Easy arc starting and concentrated arc characteristics help improve welding control, support smoother bead appearance, and reduce spatter during stainless and ferrous-metal applications.
Suitable for stainless steel, alloy steel, carbon steel, and other ferrous metals
As a DC TIG machine, TIG-250D is built for iron-based materials rather than aluminum welding, making it a strong fit for stainless steel fabrication and general ferrous workshop jobs.
Compact lightweight structure with simple controls for workshop and outdoor use
The 10.22 kg body, straightforward operating interface, and stable output characteristics support convenient transport, quick parameter adjustment, and reliable portable deployment.

DC versus AC/DC TIG at a glance
- TIG welding is divided into DC and AC/DC types.
- DC can weld iron and stainless steel.
- AC/DC can weld aluminum, iron, stainless steel, copper, and other non-ferrous metals.
- Choose TIG-250D when stainless and ferrous work matters more than aluminum capability.
Built for flexible workshop and field deployment
- Stainless steel fabrication up to 4 mm
- Carbon steel and alloy steel welding tasks
- Maintenance, repair, and portable field service work
- Shops that may use either 220V or 380V supply conditions
Choose DC inverter TIG for stainless and ferrous work, or AC/DC inverter TIG when aluminum capability is required.
This lineup separates inverter TIG machines by current type and material focus. DC models are built for iron and stainless steel welding, while AC/DC models extend coverage to aluminum, copper, and other non-ferrous materials.
