This serves as a steady during welding or as a support when the unit is set
aside. As an accessory, a clamp can be supplied for the workbench (Fig. 2 (2)),
which can be used to secure the unit in a horizontal or vertical position.
Supporting the sleeve welding unit FM
The unit should rest on the support stand (1) or be fixed on a workbench by
using the bench support (2).
CAUTION
When the unit is hot, hold it only by the handle (3). Do not touch the
heating element (4), the welding tools (5) or the metal parts between the
handle (3) and heating element (4), otherwise a burn injury may result.
2.3. Selection of welding tools EE
The choice of welding tools, i.e. heating spigot and heating socket (Fig. (3),
depends on the size of pipe to be processed. The tools themselves are mounted
to the heating element with the allen key supplied, as shown in Fig. 1 (5). The
plug can be prevented from secured twisting with the pin, which is also supplied.
Depending on the model specification and intended application, two or more
welding tools can be mounted to the heating element at the same time.
Selection of welding tools FM
Select welding tools (5), heating spigot and heating socket, according to the
pipe size. The tools are mounted on the heating element (4) with the allen key
supplied. Two welding tools can be mounted on the heating element at the
same time.
2.4. Electronic temperature control EE
According to DIN 15960 and DVS 2208, Part 1, the temperature of the heating
element should be capable of being adjusted in fine stages. In order to ensure
that the heating element operates at the required constant temperature, these
machines are equipped with a thermostat. DVS standard 2208, Part 1 specifies
a maximum differential of 3°C between the preset and actual temperatures. In
practice, this degree of accuracy cannot be achieved mechanically, but only
by an electronic thermostat. For this reason, therefore, welding machines
operating at a fixed, preset temperature or employing a mechanical thermostat
may not be used for welding operations as described in DVS 2207.
The temperature can be adjusted on all REMS sleeve welders EE. They are
supplied with an electronic thermostat. The type of thermostat fitted is identified
on the rating plate by code letters, examples of which are given below:
for ex. REMS MSG 63 EE: Adjustable temperature (E), electronic thermo stat
(E). The preset temperature is adjusted to within +/- 1°C, i.e. with a preset
temperature of 260°C (welding temperature for PP), the actual temperature
will fluctuate between 259°C and 261°C.
Mechanical temperature control (thermostat) FM
The required operating temperature is set at 260 ±10°C. Pay attention to the
manufacturer's information pipe and fittings! Before starting any welding work,
the temperature on the surface of the welding tools should be monitored.
2.5. Preheating of the sleeve welding unit EE
As soon as the connecting lead is connected to the mains, the welder will begin
to heat up. The red power-on indicator lamp (6) and green temperature indicator
lamp (7) light up. The machine requires about 10 minutes to heat up. Once the
required preset temperature is reached, the built-in thermostat cuts out the
power supply to the heating element. The red indicator lamp continues to glow.
The green tempe rature indicator lamp lights up intermittently, indicating the
repeated switching on and off of the power supply. After a further 10 minutes
waiting time, (DVS 2207, Part 1), welding operations can begin.
Preheating of the sleeve welding unit FM
As soon as the connecting lead is connected to the mains, the welding unit
begins to heat up. The green power-on indicator lamp (6) and the red temper-
ature indicator lamp (7) light up. The unit requires about 10 min. to heat up.
Once the required temperature is reached, the built-in thermostat cuts off the
power supply to the heating element. The red temperature control lamp turns
off. Whenever the red temperature control lamp is lit, the no welding should be
carried out.
2.6. Selecting the correct welding temperature EE
The welder heating element is preadjusted to the average welding temperature
for PP pipes (260°C). Depending on the pipe material and gauge of the pipe
walls, it may be necessary to adjust this temperature. In this case, observe the
manufacturer's information on the pipes or mouldings without fail. In addition,
the temperature of the welding tools (spigot and socket) should be checked
with an electric surface thermo meter. If necessary, the temperature can be
adjusted by turning the temperature adjusting screw (8). In this case, it should
be remembered that the heating element must not be used until 10 minutes
after the preset temperature has been reached.
3. Operation
3.1. Description of process
In welding with the sleeve welder, the pipe and sleeve are welded together
overlapping. The end of the pipe and moulded sleeve are heated to welding
temperature by means of the welding tool (spigot and socket), then welded
together. The end of the pipe and fitting are matched to the welding spigot and
socket respectively in such a way that a build-up of pressure takes place in
the joint when the two components are mated (Fig. 4).
