Product Characteristics

The TIG-400P ACDC, TIG-350P ACDC-W, and TIG-400P ACDC-W deliver versatile AC/DC TIG and MMA welding for steel, stainless, and aluminum. Featuring sine/triangle/square waveforms, precise pulse control (DC: 0.2–500Hz, AC: 0.2–200Hz), and torch modes (2T/4T/4T2/SPOT), these inverters optimize bead quality and heat management. Industrial durability (60% duty cycle, IP21S/F-class insulation) pairs with parameter memory, 6-pin amperage pedal control, and air/water cooling for demanding workshop reliability.

	2T/4T & SPECIAL MODE
	Effortlessly switch between 2T (temporary) and 4T (continuous) welding modes for optimized workflow. Specialized torch functions like 4T2 (multi-cycle) and SPOT (timed pulse) enable flawless tacking, intricate joints, and repeatable results across all materials.
	AC & DC Welding
	Master aluminum, steel, stainless, and more with dual AC/DC TIG & MMA modes. AC mode features adjustable 20–250 Hz frequency and 20–70% balance control for clean oxide removal. DC mode delivers ultra-precise arcs down to 10A starting current – ideal for thin gauges.
	SAVE PROGAM
	Lock in custom parameters for repeat projects! Save and recall up to 10 welding programs – including pulse settings, slope times, and gas controls – ensuring consistent quality across jobs without tedious reconfiguration.
	REMOTE CONNECTOR
	Plug-and-play compatibility with 6-pin foot pedals for real-time amperage adjustments during TIG welding. Includes a 50M wired MMA remote for stick welding flexibility across large workspaces.
	INTELLIGENT COOLING SYSTEM
	Integrated air/water cooling (standard on -W models) with auto-switching and pressure protection. Maintains optimal temperature during 60% duty cycles at 400A, preventing overheating even in high-output applications.

Advantages

Multi-process versatility; Precision control; Heat management; Material-specific waveforms; Delicate welding; Ergonomic modes; Parameter memory; Cooling protection; Industrial durability.

Key Features
