It is a great kit to weld plastic -1. clean sections, 2. Staple part is the tack weld. 3 is trim the staples, 4. is finish weld (fill in the tack weld) 5 final clean and prep and apply any finish.
it is the second plastic welder kit I have bought, and the hot stapler to join sections together works very well. But plan on what side to use the staples, and buy a durable pair of cutters the staples are very durable. (hard to cut). If you are going to use many staples you should use a pair of needle nose pliers load staples into the end. It will get hot do not use your fingers to load staples.
After stapling use other weld tool to filling and smooth. Kit is very easy to use. for th price it as much as I need.
