The price of the device was great, so for home use it will definitely find use for occasional work on welding PVC films, so then I will write how it met my requirements. It is currently in the middle :)
Tested the roofing welder and it function very well. Both the niple 40 mm and the roller is perfect. The heat adjustment is easy to perform and the welding sems becomes solid vulcanized.
Excellent !!! Great service! The machine works very well and it is Easy to use! Very good choice! Accurate description and the delivery time was ok. Thank you
