Feature： Combining the most potent welding and cutting tools into an easy-to-use professional machine, The Firstess YWT-211ACDC is multi-functions in 1 machine, allowing to cycle through High-frequency AC/DC TIG, Lift TIG, Pulsed High-frequency AC/DC TIG, Lift TIG, Cold Spot TIG,  and Stick welding. As a result, this welder offers a great combination of features for everyday TIG/Stick projects. Intuitive and Easy-to-Use Control Panel Color LED Screen: Visualizes the welding process and parameters for easy monitoring.Effortless Adjustments: The value knob and buttons provide quick access to welding modes and parameter settings.Versatile Mode Selection: Easily switch between 2T/4T/Foot Pedal (Remote) mode, and choose from Stick, Lift TIG, High-Frequency TIG, Pulse TIG, and Cold Spot welding. Remote Amperage Control for Hands-Free Operation Compatible with a 5-Pin Foot Pedal: Allows real-time control of welding current remotely.Supports Both Foot Pedal (not included) and Torch Remote Control (not equiped): Perfect for maintaining precise control while welding. Note: The foot pedal is not included. If using a different brand, ensure wire compatibility. 2T/4T mode is unavailable in foot pedal mode. Lift TIG Welding – Smooth Arc Ignition Touch & Lift Ignition: Ensures a stable arc start without damaging the tungsten.User-Friendly & Reliable: Minimal sticking and excellent arc control for precision welding. Pulsed TIG Welding – Ideal for Thin & Delicate Materials Low-Heat Precision: Adjustable pulse settings minimize heat input, reducing distortion on stainless steel and non-ferrous metals.Spatter-Free Welding: Smooth and controlled arc with a minimum 5A output, perfect for highly conductive materials. Cold Spot TIG Welding – Protects Thin Metals Controlled Heat Application: Reduces the risk of deformation and discoloration.Perfect for Precision Spot Welding: Ideal for thin and delicate metals.Includes a Spot TIG Torch: Comes ready for cold spot welding out of the box. Reliable & Efficient Stick Welding Arc Force: Maintains arc stability by compensating for voltage fluctuations.Hot Start: Boosts amperage for a smooth and easy arc ignition.Anti-Stick Function: Prevents electrode sticking by automatically cutting off the current. This welder combines intuitive operation, advanced welding capabilities, and superior remote control options, making it an excellent choice for both professionals and hobbyists!
