Expert Verdict — Reviewed by the SuperArbor Pro Desk
Heating elements are the most common wear item on hot air welders; heat output fades gradually and seam quality drops before the element fails outright. Track welder temperature and keep a genuine 142.718 element in the service kit. Always replace with genuine Leister parts so welder performance and warranty coverage stay intact.
Disconnect the welder from power and let it cool completely before replacing the heating element.
Order the genuine Leister Triac ST heating element 142.718 and keep your welder at full temperature.
