That lead wouldn't even pass a visual inspection for commercial test & tag. It is illegal to sell in Australia due to no insulation on the pins. There must be someone you can report this too, those twisted wires are a not very funny joke... very dangerous.
Exactly which is why I changed it over.... 240V connection is now soldered with heat shrink covers. Earth is now looped through the pins... handle??? - Will have to sort that one out with some plastic material of sorts
Devices such as heating elements ( this is what this is) should NOT be soldered as the heat from the unit could melt the solder.
