It is easy to wipe off when wet, and it is not durable.
2. Poor protection against contact with live parts.
3. Power deviation
Deviation of input power exceeds the standard; Some don't even specify the rated input power.
4. Quality problems
There are serious quality problems in power cord insulation sheath, input socket pin, handle, knob and test angle bottom plate. Among them, the temperature rise of the knob, the bottom plate of the test angle and the pins of the electrical input socket is out of tolerance, mainly because these parts are too close to the heat source.
5. Abnormal work
The melting of the chassis makes the temperature rise of the bottom plate at the test angle about 400 K.7. Structure.
