          TECHTIPS


          Recently, I visited a client that utilizes a battery of Mitsubishi AWT machines in a medical production situation. The
          client was having some issues creating a good threading tip for starting new spools, so I recommended the lighter
          method used successfully by a majority of Wire EDM users. However, lighters are forbidden in this medical facility,
          so what to do?



          ANOTHER SOLUTION

          Being the combination of an engineer, toolmaker and
   EDM Today Magazine                           EDM Today Magazine                            EDM Today Magazine
          gearhead, I can be a shameless copier of a good idea
          that’s in the public domain. Therefore, I took it upon
          myself to replicate the aforementioned Charmilles wire
          preparation device and made it portable. I copied the
          pin and heat shield dimensions along with the ten inch
          separation. Rather than utilizing a transformer which
          would require fusing, a power cord and GFI for an
          environment with adjacent water, I utilized a series-par-
          allel battery bank of D cells for power. The end result
          is shown in Figure 7, is completely portable and works
          perfectly with all wire types including hard and soft
          brass, D-type wires with Cu80:Zn20 core and X-type                        Figure7
          wires with 100% Cu core.

          Hopefully, the information in this article will forever put to rest complaints that oversize wires are causing
          threading issues.
