Product Characteristics

The TIG 225 / 245 / 250 / 315 DC argon arc welding machine is a professional multi-functional inverter, specially designed for DC and manual arc welding (MMA). The TIG 225 / 245 / 250 / 315 is specifically designed for welding low-carbon, alloy, stainless steel and alloys. It features non-contact arc ignition and protective gas valve, as well as high-frequency control of the welding gun button (TIG HF). In this argon arc system, the welding current is not sensitive to changes in power supply voltage and arc length, thereby providing better welding quality. During TIG welding, various convenient functions are also provided: smooth current reduction at the end of welding, and blowing at the end of welding. There is a digital display on the front panel of all machines, used to monitor the set welding current.

	2T / 4T MODE
	The TIG-225 series supports two welding torch modes: 2T Mode: Press and hold trigger to start welding; release to stop. 4T Mode: Press/release to start → Press/release to end. Ideal for long welds, freeing welders from continuous trigger hold.
	2-IN-1 VERSATILITY
	Due to its multi-functional nature and the ability to switch between two welding modes, this machine enables you to perform the following types of work: direct current argon arc welding (TIG AC) and manual arc welding using coated electrodes (MMA).
	OVERLOAD PROTECTION
	Undervoltage, overvoltage, overcurrent Protection
	EXTENDED EQUIPMENT
	Welding torch, welder's protective cover, brush, air hose, fixture, spare parts kit - This kit contains everything needed for a quick start of work.

Advantages

IGBT inverter efficiency; triple voltage/current protection; TIG/MMA switching; adjustable post-flow gas; 2T/4T torch modes; dual-board thermal control; multi-insulation IP21S safety.

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.

Setup Rules

Avoid dust/metal powder, corrosive gas. Op. temp: -10°C~40°C; storage/transit: -25°C~55°C. Max 15° tilt. Dry & ventilated (<90% RH), no sun/rain. Windshield weld zone. ≥20cm wall clearance; ≥30cm machine spacing.
