- This SCR DC TIG model is positioned for precision sheet and workshop welding with dependable transformer-style operation.
- Single-phase 380V input supports sites that need broader available TIG output.
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.
