How to Use the Coldheat Soldering Gun

by Jonra Springs

Use the Coldheat soldering gun to execute small soldering jobs in seconds. The cordless Coldheat tool transfers heat faster than a soldering iron or solder gun. The tip of a Coldheat gun is made of two separated electrodes that become a circuit when connected by touching the conductive metal of solder, wire or a connector terminal. The circuit generates heat to 500 degrees in one second and the temperature continues to increase for as long as the tip is against a metal. The tip then cools to touch in a matter of seconds after being removed from a metal surface.

How to Use the Coldheat Soldering Gun

Step 1

Set up the Coldheat soldering tool. Remove the protective cover from the tip and insert it into the opening at the end of the unit, so the inner contacts fit into the slots of the tip mount. Remove the screws at either end of the dark gray battery cover on the underside with a Phillips screwdriver. Pull the cover off to open the compartment. Slide AA batteries into the compartment in two rows with the positive ends toward the tip. Replace the cover and tighten the screws.

Step 2

Turn on the Coldheat tool. Push the sliding switch to the "On" side. The power usage red light will come on and the white pen light sends a beam in the direction of work if the unit is functioning properly. The tip will not generate heat until it touches a conductive metal.

Place solder against the tip so it touches both sides of separated tip. Touching only one side of the tip does not complete the circuit that transfers heat to the metal. Remove the Coldheat soldering tool from contact with the metal as soon as possible. The tip continues to heat for as long as contact is maintained.


  • Avoid exerting pressure that presses the tip against your work components. The small ends of the tip can break easily under pressure while heating. Do not touch the tip of the Coldheat tool anytime the red power light is on. The Coldheat soldering gun is not intended for use with extremely small or temperature sensitive components. Check the heat tolerance of any questionable components.


  • Try optional tip shapes available from Coldheat. The tool comes with a bevel tip, but chisel and cone shapes are also available. View the tip shapes at Think Geek dot com. A link is featured in the resources section.
