The Model PHP handpiece is used to weld small parts which require less than 125 watt-seconds or 1/2 cycle AC, and welding forces less than 7 pounds.

Handpieces are available with either 4-foot or 10-foot long cables.  As a general rule, the energy delivered to the workpiece with 10- foot #6 cables will be approximately 15% of that delivered with 4-foot #6 cables. Handpieces are furnished with cables, as indicated in the following table, and one pair of RWMA electrodes.
