Precision MultiAngle Tungsten Grinder for Professional TIG Welding Four Optimized Sharpening Angles: Choose from 10°, 15°, 20°, and 22.5° to achieve precise tungsten tips tailored for AC or DC TIG welding. Consistent angles ensure stable arcs, cleaner starts, and minimal contamination, resulting in professionalgrade welds every time. Wide Electrode Compatibility: Adjustable brass guide screws securely hold tungsten electrodes from 0.04 inch up to 1/8 inch diameter without the need for extra parts. Ideal for both fine, delicate welding and heavyduty fabrication tasks. Durable CNCMachined Construction: Made from quality aluminum alloy, weighing only 14.1 ounces, this grinder offers a lightweight yet stable grinding experience. The solid build reduces vibration and delivers longlasting reliability with consistent precision. Fast Wheel Replacement: Openhead design allows diamond grinding wheels to be swapped in under 30 seconds with no tools required, keeping downtime to a minimum and productivity . Use Scenarios: 1. Preparing ultrasharp tungsten tips for thin stainless steel tubing to prevent arc wander and ensure clean bead appearance. 2. Grinding sturdy tungsten electrodes for amperage aluminum welding in fabrication shops, where tip consistency is critical for smooth starts. 3. Quick maintenance onsite for varied TIG welding projects, changing grinding wheels effortlessly to match the job at hand. This precision tool delivers consistent results, extends electrode life, and provides a dependable solution for welders seeking accuracy, efficiency, and durability in their tungsten preparation process.
