MTH, PHP, THP, GHP, HFP – Hand Held Units
MIYACHI UNITEK provides a variety of resistance welding accessories such as handpieces, foot switches and electrode materials.
• Both the Model THP tweezer, and PHP probe handpiece are used
to weld small parts which require less than 125 watt-seconds or
1/2 cycle AC, and welding forces less than 7 pounds. The Model
HFP high force probe is used for applications which require higher
energy and/or force than either THP or PHP. All three models are
force fired to ensure repeatability.
• The Model GHP and HDHP are switch fired handpieces and can be
used to weld or tack materials that don’t require stringent force control.
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
