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
