Feed rollers and hot-air pressure, heat-sealing temperature and speed

Switch the machine on.

Before changing the feed roller and hot air pressure, the pressure on the

appropriate regulator must first be set at 

"0"

. The required pressure can then be

set.

Hot-air pressure

 

(only for machines with hot air):

Set the hot-air pressure on regulator 

1

 according to the material of the workpiece (at least

0.3 bar

).

Before switching the main switch on, make sure that the hot air pressure is

above 

0.2 bar

!

If the hot air pressureis too low, the heating switches off automatically.

Feed roller pressure:

Set the feed roller pressure (see Chapter 7.10) according to the material of the workpiece

(

max. 5 bar

).

Heat-sealing temperature:

Set the heat-sealing temperature on buttons 

2

 according to the material of the workpiece

- hot wedge model max. 

550ºC

- hot air model max. 

650ºC

.

Display 

3

 shows the required temperature and display 

4

 the actual temperature.

Heat-sealing speed

Set the heat-sealing speed (see Chapter. 7.07) according to the material of the workpiece

(

max. 10 m/min.

).
