TGZ370 - Aurora 6-Inch Stainless Steel Digital Caliper with LCD

Essential Accuracy for Fabrication and Welding

In the world of welding and metal fabrication, precision is the difference between a perfect fit-up and a costly rework. The Aurora 6-Inch Digital Caliper provides welders and fabricators with the accuracy needed to verify material thickness, check root openings, and measure finished dimensions with confidence. While tape measures are standard for rough cutting, a high-quality digital caliper is indispensable for the critical tolerances required in structural and precision fabrication work.

Constructed from hardened stainless steel, this tool is tough enough to survive the metalworking environment. Its robust body resists the nicks and scratches common in fabrication shops. The caliper allows you to quickly verify that your stock material matches the print specifications—crucial for setting up your welding machine parameters correctly. Knowing the exact thickness of your base metal ensures you select the right amperage and wire feed speed, leading to better penetration and weld quality.

Streamline Your Fit-Up Process

Fit-up is king in welding, and the Aurora Digital Caliper is your best ally. Use the internal jaws to measure the gap between plates or the inside diameter of pipe fittings to ensure proper alignment before tacking. The depth rod extending from the end of the beam is perfect for checking the depth of blind holes or verifying the height of a weld reinforcement. With the large LCD display, you can read measurements at a glance, even through a welding helmet's passive lens or in dim shop lighting.

The tool's ability to zero at any position is particularly useful for checking tolerances. You can measure a standard part, zero the caliper, and then measure subsequent parts to instantly see how much they deviate from the target—positive or negative. Additionally, the instant Inch/Millimeter conversion saves time when working with mixed-unit drawings, eliminating the need for manual math and reducing the risk of cutting errors.

Fabrication Applications

• Material Verification: Instantly confirm sheet metal gauges and plate thickness.
• Gap Checks: Precisely measure root openings for consistent weld penetration.
• Quality Control: Verify finished part dimensions against blueprints before shipping.
• Tool Setup: accurately set fences and stops on bandsaws and drill presses.
