The S-24 was the original DUS TIP developed by Hughes Aircraft. This series is a single ended deep access parrallel gap electrode with an insulator (spacer) that binds the two halves together and establishes the width of the gap. The Hughes DUS TIP used pins and screws to bind the two halves together. This design uses an adhesive insulator which is a much more economical design that works very well. Custom materials are available. Contact the factory for assistance at (870)-269-4367.

S-21 Round Tip

The S-21 series is a fully customizable spot welding round electrode available in multiple materials.  See the drawing for an understanding of the various dimensional values and construction of this electrode.  It comes with a .125” or .250” diameter copper body.  Glidcop and copper versions are built from one piece, and essentially any A value larger than .025” diameter is acceptable in these two materials.  Tip materials of class 11 copper-tungsten, class 13 pure tungsten (W), and molybdenum (M) have the tip pressed into the shank, with standard A values for pressed materials being .062” , .093” , and .125” .  Other A values requested in pressed materials will be constructed by inserting a standard A diameter material size, and then resizing the end of the tip.  Please note that requesting non-standard A dimensions with class 11 copper-tungsten, class 13 pure tungsten, and molybdenum materials will add additional cost to the base price of the electrode.  Adding a –B to the end of the part number makes the tip brazed into the copper shank.  Adding a -P to the end of the part number makes the tip pressed into the copper shank with no brazing. Tip sizes with an A value larger than .125 are always brazed onto the copper shank.  While brazing the tip material into the shank adds some additional cost to the electrode, we highly recommend using this option, as it produces a superior electrode.  An electrode with a pressed tip and no brazing has the potential for the resistance to change due to oxidation of materials at the joint between the tip and shank.  This can lead to inconsistent welding results.  Custom materials are also available.

S-20

The S-20 series is a parallel gap electrode design for use in the Miyachi Unitek round electrode holders, and functions the same as the Miyachi Unitek Unitip C series electrodes. This electrode is functionally the same as our S-23 series, but more expensive. We advise picking an S-23 design with equivalent tip size if you need this electrode.  The S-23 offers better clearance angle and works the same as this S-20 electrode.

S-19

The S-19 series is a round electrode with a flat face and a tapered angle leading up to the tip.  See the drawing for an understanding of the various dimensional values and construction of this electrode.  It comes with a .125” or .250” diameter copper body.  Glidcop and copper versions are built from one piece, and essentially any A value larger than .025” diameter is acceptable in these two materials.  Tip materials of class 11 copper-tungsten, class 13 pure tungsten (W), and molybdenum (M) have the tip pressed into the shank, with standard A diameters for pressed materials being .062” , .093” ,and  .125”.  Other A values requested in pressed materials will be constructed by inserting a standard A diameter material size, and then resizing the end of the tip.  This electrode also has an optional tip radius “R” that can be added to the electrode if needed.  Leave the R value completely out of the part number if you do not need this clearance angle.  Please note that requesting a R radius, as well as using non-standard A dimensions with class 11, class 13, and molybdenum materials will add additional cost to the base price of the electrode.  Adding a –B to the end of the part number makes the tip brazed into the copper shank.  Adding a -P to the end of the part number makes the tip pressed into the copper shank with no brazing. While brazing the tip material into the shank adds some additional cost to the electrode, we highly recommend using this option, as it produces a superior electrode.  An electrode with a pressed tip and no brazing has the potential for the resistance to change due to oxidation of materials at the joint between the tip and shank.  This can lead to inconsistent welding results.  Custom materials are also available.
