Product Characteristics

The TIGMaster-200COLD TIGMaster-250COLD and TIGMaster-315COLD are powerful, feature-identical DC inverter TIG welders (250A/315A) offering exceptional versatility with 4-in-1 modes: COLD TIG, high-frequency PULSE TIG (500Hz), MMA, and LIFT TIG. Engineered for precision and ease-of-use, they boast adjustable gas control, specialized torch triggers (2T/4T/4T2/SPOT), Hot Start, Arc Force, and Anti Stick, plus critical cold welding capability (1-990MS) for sensitive materials. Designed for robust efficiency, they include intelligent cooling, parameter memory, a Work Time Tracker, high-duty cycle (60%), and comprehensive protection, coming outfitted with all essential TIG/MMA accessories for high-quality results across diverse applications.

	4-IN-1 VERSATILITY
	Master any job with one machine: Seamlessly switch between COLD TIG, Pulse TIG (500Hz), MMA (Stick), and Lift TIG welding modes.
	2T/4T & SPECIAL MODES
	Gain ultimate torch control: Precision welding modes include 2T, 4T, 4T2, SPOT, and Cold Spot Time (400-990ms) for complex tasks.
	PULSE MODE
	Optimize weld quality on stainless steel and aluminum with high-frequency Pulse TIG. Adjustable pulse frequency up to 500Hz ensures controlled heat input, reduced distortion, and superior arc stability.
	SAVE PROGRAMS
	Optimize repeat jobs: Save and recall custom welding parameters for one-touch consistency.
	INTELLIGENT COOLING SYSTEM
	Built for endurance: Auto-adjusting cooling maintains 60% duty cycle, even in demanding conditions.

Advantages

DC inverter stabilizes power; Cold/Pulse/MMA modes weld nuclear pipes; 2T/SPOT assures precision; Memory settings guarantee repeatability; Cooling protects productivity.

Key Features

Inverter-based TIG series using 20-30kHz IGBT tech; compact, energy-saving. Multifunctional: WSM, DC TIG, pulsed TIG. Precise slow-start/decay control; superior arc stiffness & HF ignition success.

System Specs

60% duty cycle at max output; constant current characteristic. Exceeding cycle risks overheating and damage.
