Starting The Welding Process - WELDY booster EX2 Instrucciones De Funcionamiento

Preparation for welding
• The handle (11) can alternatively be mounted left, right or bottom of the tool.
• The tool support (3) can be mounted on the left, right or bottom of the tool.
• The minimum cross-section must be ensured when using extension cables. The extension cables must be
authorized for the utilization site (e.g., outdoors) and be marked accordingly. When using a power unit for the
power supply, it must have the following nominal power rating: two times the nominal power rating of the hand
extruder.

Warning:
Excessive heating can lead to the destruction of Teflon shoes and the development of vapors that are
harmful to health. During heating, the appliance must be supervised to avoid excessive heating.
• Connect the Weldy hand extruder to the mains supply.
• Then switch on the hot-air blower switch (13).
• Adjust the hot air temperature by the air temperature potentiometer (12) to position 5.
To reach the operating temperature, the handheld extruder requires at
least 10 minutes to heat up.
Starting protection
The hand extruder has an overload protection fuse (8). If the current consumption is too high, the drive
is automatically switched off if the material in the screw is not sufficiently plasticized. Wait 1 minute and
then press the overload protection fuse (8) to switch on the handheld extruder again.

Starting the welding process

• Attach the required Weldy welding shoe (1) as per the section "Welding shoe replacement".
• Inserting the welding rod into the welding rod opening
• Welding can begin as soon as the operating temperature is reached. To do this, press the on/off switch (10)
of the handheld extruder. The handheld extruder may only be used if a welding rod with a diameter of 3 mm or
4 mm is inserted into the welding rod opening (4). A small amount of plasticized material must be allowed to
escape before welding.
• Set the heat of the hand extruder until the ideal temperature for starting work is reached.
Heating
(position 5)
The welding rod must never be guided through both welding rod openings at the same time. The
welding rod must always be kept clean and dry.
