The UNIMIG ENVY TIG 230 AC/DC Welder Water Cooled Package is a high-performance welding machine designed for professional welders requiring precise control and versatility. It is suitable for TIG welding aluminium, magnesium, zinc alloys, mild steel, stainless steel, copper, silicon bronze, titanium, and MMA welding on mild steel, stainless steel, and cast iron.

This welder features advanced silicon carbide (SiC) IGBT technology, enabling a high switching frequency of 100kHz, which is more than double that of traditional IGBTs. This results in improved high-frequency characteristics, reduced conduction resistance, and a more stable DC current waveform with less ripple. The compact SiC IGBTs reduce electrical loss and enhance energy efficiency while offering superior impact and temperature resistance (up to 150°C), ensuring reliable performance in demanding environments.

The package includes an 8m T3 water-cooled TIG torch, an 8m T2 TIG torch, a 4m twist lock electrode holder, a 4m 300 Amp earth clamp and lead, an argon flowmeter regulator, a 1.8m quick-connect gas hose, a 15A to 10A conversion lead, and an operating manual.

Key features include:

• Dual power input compatibility (10A or 15A outlets) with adjustable duty cycles for optimized performance
• Smart fan technology for reduced noise, power savings, and minimized contamination
• Power Factor Correction (PFC) for maximized electrical efficiency and protection against voltage fluctuations
• Job memory function storing up to 100 weld parameter settings for quick recall
• 5-inch colour LCD touchscreen with an intuitive user interface
• Generator compatibility (minimum 8kVA recommended)
• IP21S protection rating against finger contact and vertical water spray
• Foot control ready with wired and wireless options for hands-free amperage adjustment

TIG welding capabilities include Speed Start™ for rapid puddle formation, Steady Arc™ for consistent weld puddles and heat input, TackPlus™ for precise tack welds, and Amplitude Control for enhanced penetration and weld speed. The TIG Smart-Set™ simplifies setup by selecting filler material, joint type, tungsten diameter, and material thickness. Mixed AC/DC welding combines AC efficiency with DC penetration for faster welds. Additional features include Tungsten Optimizer, Heat Control Trigger mode, low amp TIG stability down to 2A, Cap Shaping for optimal tungsten preparation, customizable AC/DC waveforms, and high pulse frequency up to 999 pulses per second.

MMA (Stick) welding functions include Pulse MMA for reduced spatter and improved heat control, Hot Start for arc ignition stability, Arc Force for arc length compensation, and Anti Stick to prevent electrode sticking.
