Tip Dress Pressurization
- Recommended pressure: 330lbf/1470N.
- Do not exceed 375lbf/1700N
- Recommended pressurization time: 1-1.3 second
- Longer than 1.3 seconds may result in clogging
- Standard Pressurization thickness for KTWHL Cutters: 5mm.
*Note: some applications use different thicknesses, so validate with customer drawing or manually measure.

Electrodes
Poor/Partial Dress
- This type of dress may occur when the timing of the dress needs to be adjusted or the cutter needs to be replaced
- Occasionally, this type of dress can pass a resistance check, but our TMN-01 tip monitor camera can catch this error
Optimal Dress
- This is a fully dressed electrode with a defined weld face edge
- No leftover residue is on the weld face
*Pictures taken with TMN-01 weld face inspection unit
**Dia is the weld face diameter and Rem is the reflectivity judgment
