Putting into operation
Spare part replacement
• Evaluate welding temperature: direct observation for transparent PE material, speed and temperature will be
appropriate if welding mark is flat and in transparent glass form; temperature will be too high and speed be
too slow if mark is heavily broken; temperature will be low and speed be fast if mark is not transparent and
with white. For opaque material, observe if there is obvious welding mark, also tensile test can be made after
complete cooling.
• Flatly and straightly trim the weld edges and frontage faced, with lower left and upper right overlapped. The
overlap width is 100mm.
• After temperature and speed have been determined, insert material to be welded between the two pressure
rollers, make machine body parallel with edges of base materials and engage press lever handle for proper mo-
tion. Check the welded seam (welded bead/weld path). If required, correct the speed with the
Speed control
knob (6).
• When welding will be ended, timely press lever handle to disengage upper and lower pressure roller to prevent
rubber wheel damage for long duration.
• Excessive temperature high and low may occur because of
thermal inertia. On this condition, temperature deviation may be
compensated by speed regulation on a small degree.
• A “T” shape overlap is formed between welded and additional
material. Welding method is shown as figure below, tightly butt
the overlap head of hot wedge against weld mark, and beveling
cut length is approximately 100 mm.

Replacement of hot wedge assembly
Remove the front end covering, remove the 4-M4
screws and tapping screw, remove a half housing,
release 4-M3 screws, remove the 2-M5 screws
that connect heating support and slide carriage,
remove hot wedge and replace with a new one, and
reassemble the complete machine (shown in the
following figure).
Note:
conform to color on wiring.
