The Proskit GK-390B is an 80W hot silicone glue gun with an ergonomic handle, designed for long-hour use in construction and craft applications. It uses a PTC heating element for controlled, consistent heat, reaching operating temperature in 3–6 minutes and delivering a glue flow rate of 15–20g per minute.

It accepts glue sticks with an Ø11mm diameter and operates on 110–240V input, making it suitable for use across different mains voltage standards.

Product Benefits

• The PTC heating element self-regulates temperature, maintaining a consistent 150°C melt point without requiring manual adjustment
• At 80W and 15–20g/min flow rate, the gun applies adhesive quickly, reducing waiting time between glue applications
• The 3–6 minute preheat time means the gun is ready to use shortly after powering on
• Universal 110–240V input allows use with different power supplies without a voltage converter
• The ergonomic handle reduces hand fatigue during extended crafting or assembly sessions
