Dear Leister customers
Vinyl sheet flooring installers need reliable welding tools, and reliable results are a must as it is notcost effective to test every welded seam. Leister floor tools and automatic welders provide thehighest quality repeatable results by supplying constant temperature, pressure, and speed during
operation.
A floor that is properly welded is critical when it comes to hygienically sensitive surfaces. This is
why most floors in public buildings such as hospitals or schools need to be welded properly, as
well as in public transportation facilities such as planes, trains, or buses. A high-quality weld is also
required in residential construction or offices in order to satisfy design requirements or to achieve a
specific design.
Leister's ergonomic floor tools will support you in any situation and guarantee reliable and economic
operation. We maintain a global and close-knit service and distribution network that provides fast,
reliable service.
Over the following pages, please view our extensive flooring installation tool selection throughwhich Leister can support you in your work.
I hope you enjoy reading our brochure!

Welding and Pointing
For flooring applications with surface areas that have hygienic requirements which are also exposed to moisture(wet rooms) or in rooms subject to intensive wet cleaning, properly welded floors are a must.

The Welding Process
Adhesive recommended by the manufacturer is required installing linoleum and rubber. Usually 3 to 5 mm welding rod of the samematerial, that is recommended by the manufacturer is used for welding PVC or TPU surfaces.
Before welding, the seam edges are grooved to approx. 2/3 of the thickness of the surface and then heat seam welded with thewelding rod.
It is important that the welding rod is fully melted into the milled surface created by the groover. The rod is then trimmed level to thesurface in two steps using the Leister quarter-moon knife: In the first stage, the rod is trimmed using the half moon knife and slide
immediately after welding/pointing. A second pass is made with the knife once the welded seam has completely cooled down. This
prevents the welding rod from being trimmed below the level flooring material and produces an even, flush surface.

Welding in 4 Steps
Grooving
The flooring material must be glued to the substrate using the adhesive recommended by the
manufacturer.
Caution: Before grooving, the adhesive between the substrate (screed) and the floor covering must be dry.
A groove is then milled in the floor covering using the GROOVER.
Caution: Work step by step: Groove first, then weld.

1

Different blades are used depending on the floor welding application.
Caution: This will depends upon the welding and the properties of the flooring material.
The cutting depth is determined based on the following (Fig. 1):• A maximum of half of the welding rod diameter.
• No more than 2/3 of the flooring material thickness

5 mm

4 mm

Welding – preparation
The milled groove must be positioned in the center of the seam, otherwise the weld will not beadequate (Fig. 2).
Caution: Before beginning the weld, a separate weld test must always be performed toverify the heat. speed and temperature settings are correct for each application.

2

The welding parameters must be set so that a weld bead forms (Fig. 3).

A welding nozzle with a narrow air outlet must be used in order to avoid any impairment to thesurface covering.
Caution: An impairment only becomes visible after several cleaning cycles.
Short welded seams a more easily welded with a TRIAC ST/AT or the HOT JET S than a
MINIFLOOR or UNIFLOOR machine..

Welding – implementation
Welding with an automatic welder (UNIFLOOR 500 / MINIFLOOR)Is recommended for time savings and precise / repeatable welded seam results.
Constant (high) speed
Constant pressure
Constant temperatures (UNIFLOOR 500 / MINIFLOOR with TRIAC AT)
Manual welding (TRIAC / HOT JET S / GHIBLI)
Recommended for short grooves, repairs, or transitions
For a consistent weld quality, the following must be taken into consideration:
As constant a speed as possible
As constant a pressure as possible
Constant temperature (TRIAC AT)

Cutting – step 1
The first detachment procedure takes place when the welding rod is not yet coolusing a sharpened quarter-moon knife and a slide attachment.
Caution: It is essential that the welding wire is cut in two stages.
This prevents the weld from sagging below the level surface. (Fig. 4).

4

Cutting – step 2
The second trimming procedure only takes place when the welded seam has cooled
down. The cut is made flush to the surface covering using the quarter moon knife
again.
The second cut takes place after the first cut and after a rest period.
Rest period for linoleum
approx. 15 minutes
Rest period for PVC
approx. 5 minutes

5

The surface is now able to bear a load and can be cleaned (Fig. 5).
Rest period for linoleum until it can bear a full load approx. 12 hours
Rest period for PVC until it can bear a full load
approx. 1 hour

TRIAC ST: Design meets experience
The new TRIAC ST from Leister is primarily used for welding and plastic fabrication. During its development, a deliberate choice was made to do without extra technical features. Instead it is distinguished by comfort, being reliableversatile, robust and user friendly, like its predecessor the TRIAC S. A prominent feature here is the two-component
handle, which is not only attractive, but also gives the user perfect grip. The low weight of less than 1 kg/2.18 lbs
ensures a perfect weight balance.
