Dual-voltage pulse TIG control for professional precision welding.
TIG 250P is positioned for professionals who want pulse heat control, high-frequency non-contact starts, and compact portability in a machine that can adapt to both 220V and 380V working conditions.
Adjustable peak current, base current, duty cycle, and pulse frequency
The published pulse parameter set gives operators practical control over heat input and weld pool behavior, making TIG 250P suitable for cleaner, more controlled welding on thin and moderate-gauge materials.
Operates on 220V or 380V input for broader deployment options
Its dual-voltage input expands where the machine can be used, supporting workshop installations as well as jobs that demand more flexible site power compatibility.
High-frequency ignition for cleaner starts and improved tungsten protection
High-frequency arc ignition helps start the TIG arc without direct tungsten contact, improving arc initiation consistency and helping preserve tungsten condition.
Adjustable gas timing and current rise/fall settings for better start and finish quality
Pre-flow, post-flow, current rise, and current fall adjustments give welders more control over shielding, arc entry, and crater fill behavior across professional TIG applications.
Compact inverter body sized for workshop and field use
Despite its higher output and pulse functionality, TIG 250P remains compact and easy to carry, making it practical for service professionals and fabrication teams alike.

Why TIG 250P stands out
TIG 250P offers a strong balance of pulse control, portability, dual-voltage flexibility, and weld-cycle tuning, making it a well-rounded professional choice for varied TIG work.
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.
