Transformer durability, 5 A arc starting, and thicker aluminum AC/DC welding coverage.
AC/DC TIG-350PT (TRANSFORMER) is positioned for thicker workshop welding with square wave AC/DC control, stable arc behavior from low-current starting, and process flexibility across aluminum, stainless steel, and broader mixed-metal fabrication needs.
Minimum 5 A arc start with stable arc behavior across thin, medium, and thick plates
The supplied product information positions the machine with minimum welding current from 5 A, good arc stability, and practical suitability for thin, medium, and thick plate work.
DC pulse TIG coverage for stainless steel, copper, titanium, and carbon steel work
The DC pulse TIG process is described as suitable for stainless steel, copper, titanium, carbon steel, and related fabrication materials where stable heat control is beneficial.
Rapid zero-crossing AC waveform supports stable current and arc performance
AC mode is described as providing drooping characteristics together with a rapid zero-crossing current waveform, helping support welding-current stability and more reliable arc behavior.
AC TIG for aluminum alloys together with AC/DC TIG and pulse process flexibility
AC TIG is positioned for aluminum and aluminum-alloy welding, while the broader AC/DC TIG and AC/DC pulse TIG process set helps extend the machine into mixed-metal workshop applications.
Current rise and decay functions help fill the arc crater and reduce crack risk
Current slow-rise and current-decay functions are intended to help fill the crater at arc stopping, supporting cleaner weld completion and reducing the chance of weld cracking.
Transformer-built main unit positioned for long service life in heavier workshop use
The supplied comparison states a main-unit service life of 12-20 years and positions the transformer structure as a longer-life option for customers prioritizing durability and heavier-duty equipment.
