3.2 Operating instructions
In accordance with national or EU ordinances and guidelines, e. g. DVS 2212,
Section I, only duly qualified and authorised personnel are allowed to operate the
ROWELD welding machines!
Only trained and authorised welders are allowed to operate the machine!
3.2.1 Putting into operation
Please read through the operating instructions and safety instructions attentively
before you put the butt fusion welding machine into operation!
Do not use the heating element in explosive environments or bring it into contact
with easily flammable materials.
Stay a safe distance away from the machine. Do not stand or reach into the
machine. Keep other people away from the work area.
Before every start-up, check the oil level of the hydraulic unit. The oil level must
be between the min. and max. marking on dipstick in the oil filler cap. If
necessary, add HLP 46 hydraulic oil.
Transport and set the hydraulic unit only in a horizontal position. If it is set at an
angle, oil escapes from the vented plugs with the dipstick.
 Connect the hydraulic unit to the basic unit with both hydraulic hoses.
Protect the quick couplings from contamination. Replace leaky couplings
immediately!
 Connect the trimmer unit, hydraulic unit and heating plate mains plugs to the power outlet/
supply specified on the type plates.
For P160-250/5-8B:
 The red diode “Stand by“ lights up. That is: there is a voltage being applied. Switch on
the heater element using the large pushbutton (lights up green) and select the desired
temperature (160°C to 285°C) using the “+“ or “-“ button.
Heating up of the heater element is displayed by a yellow diode on the heater element. A
horizontal bar also appears on the temperature indicator. The yellow diode goes out shortly
before reaching the set temperature (tolerance +/-3°C) and the green one lights up. After
a further 10 minutes the heating element is ready to use. Check the temperature using a
temperature measuring instrument.
Setting the off-set: press the “+“ and “-“ button at the same time. The heater element
can subsequently be calibrated using one of these buttons and an external temperature
measuring instrument.
If the heater element displays a smaller value than that on the external temperature
measuring instrument then the difference must be adjusted using the “+“ button. For
indicated values in the other direction adjust the difference using the “-“ button. If “Er1“
appears it means that the electronics are defective. “Er2“ means that the resistance
thermometer is defective or not connected.
Risk of serious injury! The heating plate can reach temperatures of over 290°C
(554°F)! We highly recommend storing the heating plate in the designated
carrying frame immediately after use!
For P355/12B:
 Turn on the main switch of the control box. The switch lights up green and the actual
temperature of the hotplate is shown on the display. Use the – and + keys to set the desired
temperature between 160°C and 270°C.
