Stable HF arc ignition, compact portability, and practical DC TIG versatility.
TIG-250mos combines MOSFET high-frequency inverter technology, dual-process DC TIG and MMA capability, and compact construction for fabrication workshops, maintenance work, and field welding operations.
Advanced MOSFET high-frequency inverter around 100 kHz
The MOSFET power platform supports efficient energy conversion, stable welding output, and practical reliability compared with conventional transformer-based machines.
High-frequency arc ignition for easy and consistent arc starts
Reliable HF arc ignition helps improve starting performance, maintain stable arc behavior, and support cleaner setup for day-to-day TIG welding work.
DC TIG and MMA output in one compact machine
Dual-process functionality expands the machine beyond TIG-only work, allowing users to switch between DC TIG precision welding and MMA stick welding applications.
Smooth concentrated arc with improved weld appearance
Stable output and concentrated arc characteristics help improve weld bead appearance, reduce spatter, and support precision welding on stainless steel, carbon steel, alloy steel, copper, and other non-ferrous metals.
Compact lightweight build for workshop and field use
The compact body and 10.5 kg class weight support convenient transport, on-site setup, and practical everyday deployment across maintenance and fabrication environments.

- Field welding and mobile repair work
- General industrial DC TIG and MMA tasks
- Sites where compact size and reliable output matter
Select compact DC TIG, AC/DC aluminum TIG, or transformer and SCR platforms by output type, cooling, and material demand.
This TIG lineup covers portable DC TIG and MMA inverters, higher-output pulse TIG machines, AC/DC inverter systems for aluminum and non-ferrous work, and transformer or SCR models for conventional workshop and industrial applications.
Portable and production-ready DC TIG machines for steel, stainless steel, repair, and fabrication work
- TIG-200, TIG-250mos, TIG-250D, and TIG-250P cover compact DC TIG and multi-process welding for workshop and field use.
- TIG-315P, TIG-400P, and TIG-500P extend the range for higher-output pulse TIG and industrial fabrication demand.
- Choose this group when DC TIG performance, portability, or wider pulse-control range is the main requirement.
AC/DC TIG systems for aluminum, non-ferrous metals, and higher-duty production welding
- AC-DC-TIG-250P, AC-DC-TIG-315P, AC-DC-TIG-315PW, AC-DC-TIG-500P, and AC-DC-TIG-500PW cover AC/DC TIG across air-cooled and water-cooled formats.
- These models are the preferred choice when aluminum welding, AC output, or longer high-load operating cycles are required.
- Water-cooled versions are better suited to continuous higher-current work where torch temperature and long-run stability matter more.
Conventional transformer-class and SCR-controlled TIG platforms for workshop durability and heavier-duty operation
- AC-DC-TIG-350PT and AC-DC-TIG-500PT serve thicker-section AC/DC TIG applications in transformer-class format.
- TIG-200SCR-1PH-220V, TIG-200SCR-1PH-380V, TIG-250SCR-1PH-380V, and TIG-300SCR-1PH-380V provide transformer SCR DC TIG coverage for conventional workshop use.
- Select this group when traditional machine construction, single-phase transformer supply, or heavier-duty shop use is preferred.
