TEMTS0550 - Tempilstik 550F Temperature Crayon

Stop Guessing, Start Welding with Confidence

When you're on the job, hitting the right pre-heat temperature isn't just a suggestion—it's often the difference between a passed inspection and a cracked weld. The Tempil Tempilstik 550°F (288°C) is your go-to tool for verifying heat instantly. Forget about fiddling with expensive infrared guns that can give false readings on shiny metal surfaces. With the Tempilstik, you simply stroke the workpiece during heating. The moment the mark melts into a liquid smear, you know you've hit exactly 550°F.

This stick is built for the real world. It comes in a rugged metal holder that fits right in your pocket, so it's there when you need it. Whether you are working on heavy structural steel, pressure vessels, or critical pipe welds, this 550°F indicator helps you maintain the correct interpass temperature without slowing down your workflow. It's cheap insurance against weld failures and rework, giving you the confidence that your base metal is ready for the arc.

Why trust Tempil? Because they invented the technology. For decades, welders have relied on the "mark and melt" method because it works every time. There are no batteries to die in the middle of a shift and no sensors to break if you drop it. Just reliable, +/- 1% accuracy that keeps your welds up to code and your projects moving forward. Simply mark, heat, and watch for the melt—it's that easy.
