1. Description of product
This chapter gives important basic information about the product and its prescribed use.
All technical details of the machine are put together as a general arrangement.
1.1. Application and prescribed use
The WIDOS WELD IT 315 Steel is made for heating element butt welding of pipes and fittings
with a diameter range of Ø = 90 - 315 mm.
It is a building site machine and is designed especially for the use on site as well as in the
workshop.
For this reason, the frame is kept small such that it can also be used in constrained positions
(e.g. building ditches).
All use going beyond is not prescribed.
The manufacturer is not responsible for damages caused by misuse.
The risk is held only by the user.
Prescribed use also means:
taking notice of all remarks in this manual

distributor with a FI-safety switch.
2.10. Dangers caused by the hydraulics
System parts and pressure hoses should be made pressureless before beginning
of any repair works. Even if the machine is switched off, pressure may be in the
hydraulic accumulator!
There is a danger of injuring the eyes by hydraulic oil squirting out.
Damaged hydraulic hoses have to be immediately replaced.
Make a visual inspection of the hydraulic hoses before each work beginning.
The hydraulic oil is inedible!

3. Functional description
Basically the international and national standard specifications are to be
fulfilled.
The plastic pipes are clamped by means of the clamping tools.
Then the foreparts are planed parallel by means of the planer, and mismatch is checked.
Now the WI HEAT®heating element is inserted and the pipes are pressed against the WI
HEAT®heating element with the defined adjusting pressure. This operation is called
"adjusting".
After the prescribed bead height is reached, the pressure is relieved and the heat-up time is
starting. Now the pipes are heated up to welding temperature.
After expiration of the heat-up time, the slide has to be opened, the WI HEAT®heating element
is removed quickly and the pipes are rejoined. The time between removing the WI HEAT®
heating element and rejoining the pipes is called change-over time.
The pipes are joined with the prescribed welding pressure and then cool down under pressure
(cooling time).
The weld joint can be unclamped, the welding process is finished.

temperature

5. Starting and operating
The instructions of this chapter are supposed to instruct you in the operation of the machine
and to lead you during the approppriate starting of the machine.
This includes:
the safe operation of the machine
using all the possibilities
running the machine economically
5.1. Starting
The machine should only be operated by trained and authorized people.
For the qualification a plastic welding exam can be taken according to DVS and
DVGW.
In case of danger unplug the machine immediately.
In case of power failure, the hydraulic system can still be under pressure.
For this reason, release pressure when required.
After completion of the welding work and during breaks the machine has to be
switched off. Further be sure that no unauthorized persons have access.
Protect the machine from wetness and moisture!
Operating the machine on construction sites is only allowed with an in-coming
power distributor with a FI safety switch according to VDE 0100.
Check the oil level of the hydraulic system before each starting in order to avoid
damages on the pump.
The oil-level must be between the two markers.
Connect the power line plug of the WI FORCE®hydraulic aggregate, the WI HEAT®heating
element and the planer to the mains, and be sure to have a correct mains voltage (230 V / 50
Hz / 16 A). or on construction sites to the current distributor with FI safety switch.
Connect the hydraulic hoses of the WI PRECISION®basic machine to the WI FORCE®
hydraulic aggregate.
Lay hydraulic and electric lines carefully (danger of stumbling) !
Take into consideration the environmental conditions:
Welding should not be carried out in direct sunlight.
If necessary put up a welding tent.
In case of ambient temperatures below 5°C the following measures have to be taken:
If need be, put up a welding tent and heat up the pipe ends.
Take measures against rain, wind and dust.
