In this video a Techspan Spark tester is used to show defects in Plastic Welding. This demonstration is done without any weld, to show you how the spark is seen to ‘arc’ across to a conductive material placed behind the work area. In this case we used a piece of steel angel behind the work area. Ideal to ensure your welding is free from any defects and to prove water tightness.
The Spark Tester can be supplied as a “kit” or with just the “tool only”. See more details, save time – buy online. http://www.techspanonline.com
