TEMTS0300 - Tempil Tempilstik 300F Temperature Crayon

The Welder's Choice for Accurate Heat Control

Achieving the correct preheat and interpass temperature is critical for preventing cracks and ensuring the integrity of your welds. The Tempilstik 300°F is the legendary tool that welders have relied on for decades to hit those temperature targets with confidence. Forget about dead batteries or finicky digital gauges; this temperature-indicating crayon is always ready to work. Simply mark your metal before or during heating—when the chalky mark turns into a glossy liquid, you know you have hit exactly 300°F.

Built for the shop and the field, the Tempilstik is rugged enough to survive in a tool bucket or pocket without losing calibration. It is the ultimate "go/no-go" gauge for heat management. If the mark hasn't melted, you aren't hot enough. If it melts immediately upon contact, you are at or above temp. This instant feedback allows you to focus on your arc rather than fiddling with settings. The 300°F rating is a common requirement for many mild steel and alloy applications, making this stick a staple in any welder's arsenal.

The Tempilstik 300°F is designed with a practical aluminum holder that provides a solid grip, even when you are wearing heavy welding gloves. It allows you to adjust the stick length as it wears down, ensuring you get full value out of every purchase. With its +/- 1% accuracy, you can sign off on your weld procedures knowing you met the code requirements. Simple, effective, and precise—it’s the smart way to manage heat.
