Welding Plastic with a Soldering Iron

Begin by thoroughly cleaning the plastic with soap and degreaser, even if it does not appear to be dirty. Sand the edges of the plastic down so that they are not jagged. Next you will plug in the Plastic Welding Kit China and give it enough time to warm up, which should only take a few minutes.

Push the two pieces of plastic together and hold them there while you run the soldering iron tip along the seam until the two pieces of plastic are partially melted together. While the pieces of plastic are still hot and movable, adjust them so that they fit together as best as you can manage.

You can strengthen the weld by adding small pieces of plastic — ideally thin strips — to the seam. Then fully melt these pieces of plastic by pressing them with the External Heating Soldering Iron tip until they are liquefied. Distribute the liquefied plastic smoothly along the length of the seam with soldering iron tip.

The last step is to go over the seam and the plastic surrounding it with the Temperature Controlled Soldering Iron using swift, smooth strokes. Once you have some practice with this technique, you should be able create an even, smooth plastic weld.
