welding cables that remain flexible at extremely low temperatures. It
also has an internal case heater to warm the electronics to an
acceptable working temperature.

o

operation will apply:
Plug the welding unit into the correct supply voltage and switch it
on.

show on the lid next to the display.
When the internal temperature warms to the correct level, the case
heater will switch off, the indicator light will switch off and the
electronics will switch on.
