b). Crimping Operation
The reference value of wire strip is 2.3mm. As wire strip length differs depending on type of wire and crimping method ,
decide the best wire strip length considering processing condition. When wire is stripped, do not damage or cut off
wire conductores.

Note 1. Crimp height at wire barrel should be set to pre-determined dimensions.
Note 2. Adjust crimp height at wire insulation barrel to the extent that wire insulation is slightly pressed,
and set it so that crimping is not excessivery.
Note 3. Crimping condition at wire insulation barrel is as below Fig.1.
Note 4. For AWG#28,#26,#24, use UL1007 type. For AWG#22, use UL1061 type.

Check of crimping appearance visually for correct crimping as referring to above Fig.2
Check the tensile strength at crimped part when operation finishes.
