The KC Welder Pro has an 80 Watt element, flat tip and a 3/16 in. hole in tip for repair rod insertion. Includes a selection of Hobie color welding rods. Fix holes and cracks or customize polyethylene products. Insert the rod into the tip and place against the product to be welded. The tip heats the plastic surface and the rod. As the materials melt, move the tip along the repair area while pushing the rod into the tip to fill the repair area with new plastic material. Plug small holes after moving accessories. Rebuild keels after excessive wear from dragging.
After having placed the order, the item arrived within 5 days via. ground transportation, a respectable turn-around time given I live in CT. The KC welder pro performs well with a deft touch. I practiced on scrap polyethylene from a discarded child's play house. I also salvaged additional scraps to use on future repair projects. It is critical to allow the iron (welder) to reach maximum heat before attempting a weld. Only then will the material not stick to the iron. My first real repair was a 1/2" x 2" hole in the bottom of a kayak at the stern. By inserting a strip of scrap poly on the inside of the kayak and holding it in place with a guitar string until the weld began to flow and adhere to the boat and scrap strip, I was able to completely repair the hole. Two people were needed for the initial part of the process. If you can access the inside of the boat or other project you are tackling, definitely weld both sides for added strength. One has the option of using the feed hole in the iron for the poly rods or melting them using the foot and not the hole. I used both with equal success. This is an excellent product that does what it is advertised to do. I do wish the manufacturer would have listed the working temperature of the iron. R.E.G.
If someone is an expert at welding or soldering they might get this product to work. I couldn't. It takes 10 minutes to heat to desirable temperature, and I was completely unable to repair a flex crack in my kayak despite 3 attempts taking 20 minutes each. I bought a flexible adhesive patch for 1/5 the price, applied it in 30 seconds, and it completely solved the problem. I do NOT recommend this product for flex cracks.
These items worked very well with other steps to plastic weld a small crack in an expensive kayak. It is not difficult or costly to perform such a repair, and these tools were a small investment.
Product works as advertised. Never thought I would need one, but it does the job nicely.
