350A output on a 50A single-phase circuit burns thick material without upgrading shop power.
400A max output with 100% duty cycle at 300A keeps production running without thermal shutdowns.
20–400Hz adjustable AC frequency tightens arc focus, improving aluminum penetration and puddle control.
30 programmable memory slots let operators recall exact weld setups instantly between repeat fabrication jobs.
Smart water-cooler with low-coolant shutdown protects torches and prevents costly mid-job equipment failures.

HTP America Invertig 400 AC DC TIG Welder Product # 601602
Includes: Invertig 400 AC DC power source, welding cart, smart water cooler, 12.5 ft 18 series rigid neck Trimline water cooled TIG torch, 12.5 ft foot pedal, flowmeter regulator, gas hose, 1 gallon coolant, 15 ft ground cable and clamp assembly Does Not Include: Gas cylinder, filler rod, power plug
Industrial AC DC TIG welding system designed for high amperage fabrication and production welding.
The Invertig 400 AC DC is a high output TIG and Stick welding machine designed for industrial fabrication and heavy duty welding environments. It supports TIG welding, pulsed TIG, Stick welding, pulsed Stick welding, and air carbon arc gouging.
The machine operates on either single phase or three phase input power. When connected to single phase 208 to 240V power it produces up to 350 amps of welding output. When connected to three phase power from 208V to 575V the machine produces up to 400 amps.
Advanced TIG controls allow adjustment of AC frequency, AC balance, waveform selection, and asymmetric arc control. The system also includes programmable memory slots for storing welding parameters used in repeat production work.
Input Voltage: Single phase 208 to 240V or three phase 208 to 575V Maximum TIG Output: 400A Maximum Stick Output: 300A AC Frequency Range: 20 to 400 Hz under 100A AC Frequency Range: 20 to 200 Hz above 100A AC Balance Range: 10 to 90 percent Programmable Memory Slots: 30 Cooling System: Smart water cooler with low coolant protection
USED For • Aluminum fabrication and heavy TIG welding • Pipe fabrication and structural welding • Motorsports and precision fabrication shops • Shipyard, rail, and industrial repair work
Not For • Shops without adequate electrical service • Portable field work requiring small lightweight machines • Users without water cooled TIG torch systems
If you do not have 208 to 240V single phase power or three phase power available, this is not your machine.
