How is it different from the PAW-22 EZ?
The PAW-12 ST is the standard version, while the PAW-22 EZ adds the EZ mechanism, which opens the blade automatically the moment the insulation is cut. Both cover 0.2-2.0 mm².
What should not be cut with this stripper?
Do not cut hard materials other than copper conductors, and note that fluororesin (PTFE / Teflon) insulation may not be strippable.
Is it marked in mm²?
Yes, the PAW-12 ST is marked directly in mm² (SQ), the way wires are labelled in installations in Romania and Europe.
