Commissioning the UNIPLAN 300
Prior to commissioning, check the
power cord (3)
, the plug,, and the extension cable for electrical and
mecha- nical damage. Damaged plugs and the extension cables must not be used, due to risk of an electric
shock. If you are using the hot-air welder on a table, take care at all times to prevent the welder from falling
off the table.
If the operation will be prolonged, we recommend the use of a guide handle. The accessories set contains a
short guide handle (working on a table) and a long guide handle (working on the ground).

At this stage, the heating is not yet turned on
Connect the device to a
socket with a protective conductor
. Any interruption of the protective
conductor inside or outside of the device is not permitted. Only use extension cables with protective
conductors.
If the device is being used on job sites, a residual-current circuit breaker must be used to protect site
personnel.
Operating readiness
Starting the device
Setting the welding parameters
The local supply voltage must match the nominal voltage specified on the device. EN 6100-3-11; UNI-
PLAN 500 Z
max
= 0.384Ω + j 0.240Ω; UNIPLAN 300 Z
max
= 0.377Ω + j 0.236Ω. If necessary, consult
supply authority. If the power supply fails, turn off the
main switch (11)
and place the
hot-air blower
(9)
into the park position, in order to avoid damage.
