• The machine must be operated only when in proper state of repair
and for one of the intended uses. Before welding, the welder is
required to make sure that the state of the machine is in order.
During transport, the facing tool and the heating element
have to be placed into the provided carrying rack at all
Important
times.

Intended Use

The Butt-Welding Machine is intended exclusively for joining plastic
pipes and fittings according to the butt-welding process with heating
element. See Section 3 for a detailed overview of the welding process
enabled by this machine.
The notion of intended use also includes:
• Compliance with the instructions in the User's Manual
• Observation of all service and maintenance intervals
All uses other than those mentioned above are not allowed
and will cancel any and all liability or warranty by the manu-

Understanding the Machine

This butt-welding machine for plastics can be used both as an on-site
and as a workshop installation, for jointing operations pipe-to-pipe,
but also for processing tees and elbows (see also the first paragraphs
of Sect. 4.3 for more detailed information on this).
The welder performs the welding process in the following manner:
• Applicable welding times and pressures are looked up in the
overview tables in the appendix.
• Pipes are clamped into the frame.
If pipes with an outside diameter smaller than the maximum
dimension of the machine are welded, select the reducer set
needed. The 8 individual inserts of the set that matches the out-
side diameter of the pipe to be welded have to be attached to
the clamps of the machine chassis using the provided bolts.
• Pipe butts are worked using the pipe facing tool.
• Pipe alignment is checked.
• The drag pressure, i.e. the minimum pressure to set the carriage
in motion and "drag" it along, is recorded at the machine.
