TIG 400P DC Pulse TIG Welding Machine
The TIG 400P is a powerful industrial DC Pulse TIG welding machine built for higher-current fabrication. With AC 380V input, up to 400A output in both MMA and TIG modes, programmable upslope and downslope control, and 1-20Hz pulse adjustment, it is designed for workshops that need strong, versatile, professional welding performance.
TIG 400P combines strong 400A output, dual-process MMA and TIG capability, and precise current slope control to support more demanding production welding and fabrication workloads.

400A pulse TIG output with full weld-cycle control for demanding fabrication.
TIG 400P is suited to workshops that need higher current, flexible MMA and TIG performance, and precise adjustment over arc start, arc finish, and pulse parameters for professional welding control.
Delivers MMA and TIG output up to 400A from the same machine
The official specification positions TIG 400P as a high-capacity dual-process platform, helping shops cover both precision TIG welding and general manual arc work without moving to separate machines.
Independent arc start, arc end, upslope, and descent adjustments
Current adjustment at the beginning and end of the weld cycle, together with 0-10 second upslope and descent controls, helps improve start quality, crater handling, and overall process consistency.
Broad pulse and base-current control for heat-input management
With published pulse current, base current, and 1-20Hz pulse frequency adjustment, TIG 400P offers practical control over bead shape, heat concentration, and welding rhythm.
Built for stronger fabrication demands with a 400A working range
Its 15-400A output range makes TIG 400P suitable for heavier fabrication than compact portable TIG systems, giving workshops more headroom for demanding projects.
Robust 25kg format for stable industrial use
The 25kg machine body supports a more industrial-class power stage while remaining practical for installation into workshop bays and production environments.
Where TIG 400P works best
- Heavy fabrication workshops
- Industrial TIG and MMA support
- Jobs needing weld-cycle adjustment
- Production bays with AC 380V supply

Why TIG 400P is built for demanding work
TIG 400P offers higher output and deeper weld-cycle control than lighter pulse TIG machines, making it a practical option for shops that need stronger, more configurable industrial performance.
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.
