Current Flow & Times
Current flow measured in Amps is the factor that determines the temperature of the weld.
When the Powercore Welding Rod is placed between two pieces of plastic, it requires a minimum of 6 amps of current to reach a stable welding temperature (for HDPE 3/16". Rod under certain conditions). Higher current can be used when a faster welding time is needed, or a material thicker than 1/2" is to be welded.
Decreasing Weld Time:
To decrease heat-up time, a two step current flow may be used. For example 0.060" (1.53mm) sheet can be welded at 15 amps for 55 seconds, then 6 amps for 60 seconds. Extreme caution must be used, if current is left at 15 amps for too long, a fire may result!
