of cooling the tool. Do not cool the welder submerging it in water, which may lead to electric shock. 

Do not install more than one set of adapters. This will reduce the risk of burns. Adapters may be replaced only once they have 

cooled down completely. While replacing adapters, it is required to disconnect the power supply cord of the welder from the mains 

socket. Before work may commence, make sure the adapters are tightly installed on the heating head. 

The welding operation must not be repeated using the same connecting element, since this might expose the active parts.

This appliance can be used by children aged from 8 years and above and persons with reduced physical, sensory or mental ca-

pabilities or lack of experience and knowledge if they have been given supervision or instruction concerning use of the appliance 

in a safe way and understand the hazards involved. Children shall not play with the appliance. Cleaning and user maintenance 

shall not be made by children without supervision.

USING THE TOOL

Before work make sure the housing, the connection cord with the plug and the external extension cords are not damaged. If 

necessary clean the tool and the ventilation slots. Do not clean the welder with metal tools which might damage the surface of the 

connection elements or the heating head. In case any damage is detected, it is prohibited to continue work!

Attention! 

Any actions related to replacing pipe adapters, cleaning etc. must be carried out while the tool is off, so before such 

actions: 

Remove the plug of the tool from the mains socket!

Installation of pipe adapters (II)

Select the set of adapters corresponding to a single diameter. Make sure the contact surface between the heating head and the 

adapters is not dirty. Screw the adapters tightly at both sides of the heating head. The place of installation of the adapters to the 

heating head must be selected complying with the rule that smaller adapters must be installed closer to the end of the head. The 

edge of the adapter must not protrude beyond the limit of the heating head. 

Only one diameter of adapters may be installed at one time. 

Heating

Once the installation has been finished, place the welder on the support (III). Make sure the pipe adapters and the heating head 

are not in contact with other objects. Connect the plug of the power supply cord to the mains.

The display will show the current temperature of the heating element. 

Once the „MODE” button has been pressed, the temperature adjustment mode is selected. The temperature may be adjusted with 

the „UP” and „DOWN” arrows, adequately increasing or reducing the displayed value. It is possible to adjust the whole number of 

grades or each digit separately, which permits quicker adjustments of the required value. Switching between the digits is realised 

with the „LEFT” arrow. The digit which is being adjusted is pulsating. 

Once the temperature has been adjusted, press again the „MODE” button. This will start the heating process signalled by a pulsat-

ing „OUT” light. The increase of the current temperature may be observed in the display. 

If the „OUT” light stops pulsating while the „ALM” light is on, the set temperature has been reached. The welder is ready for work.

ATTENTION!

 At the end of the heating process the „ALM” light goes on while the „OUT” light is pulsating, which indicates a close 

end of the heating process.

ATTENTION!

 During work the „OUT” light may be pulsating periodically, which indicates heating of the head. 

ATTENTION!

 The display may indicate a slightly different temperature than the value set by the user. This is a normal effect 

related to thermal inertia.

Welding

The elements to be welded must be cleaned of any dirt, humidity and dust.

Once the heating process has concluded place a pipe or connecting element on the adapter (V). Place one part on the adapter 

and the other one in the adapter so that there is a slight difference of the diameter of the elements being welded. 

Leave the elements on the adapter for the time indicated in the table. Then the welded elements must be removed from the adapt-

ers and connected by inserting them into each other. Do not insert the elements deeper than the limit of the heated area. Leave 

the connection to cool down, avoiding any deformation.

Once the work has concluded turn the welder off disconnecting the plug from the mains. Place the welder on the support until it has 

cooled down completely. Disassemble the pipe adapters and carry out maintenance actions of the tool and the adapters.

MAINTENANCE AND OVERHAUL

ATTENTION! Before any adjustment, technical service or maintenance operations unplug the tool. Once the operations have been 

finished, the technical conditions of the tool must be assessed by means of external evaluation and inspection of the following 

elements: body and handle, conductor with a plug and deflection, functioning of the electric switch, patency of ventilation slots, 

sparking of brushes, noise level of functioning of bearings and gears, start-up and smoothness of operation. During the guarantee 

period, the user cannot dismantle the electric tools or change any sub-assemblies or elements, since it will cancel any guarantee
