GENERAL
The use of GAMMA 110 is reserved exclusively for trained and suitably skilled users.
Use the machine exclusively for purposes described in chapter 2 “Field of application” and in accordance with the
operating and maintenance instructions, Any other type of utilization is considered as improper use and therefore
prohibited because of the risk of serious injury of operators, other persons and/or damage to the machine and other
property.
It is prohibited to remove any safety device (switches, microswitches, seals ecc.).
Immediately replace all worn or damaged parts using exclusively Ritmo original spare parts.
All repairs on the machine must be performed by skilled and qualified personnel.
SAFETY ALERTS
When you see this alert sign , carefully read hat it says:
YOUR SAFETY IS AT STAKE.
You will see the hazard alert sign followed by one of these words:
indicates and imminently hazardous situation

which, if not avoided, will result in death or serious injury.
Indicates a potentially hazardous situation which,

if not avoided, could result in death or serious injury.
Indicates a hazardous situation which, if not

avoided, may result in minor or moderate injury
In this manual you should look for two other words: NOTICE and
IMPORTANT.
NOTICE: can keep you from doing something that might damage
the machine or someone's property. It may also be used to alert
against unsafe practices.
IMPORTANT: can help you do a better job or make your job

easier in some way.

2. Heating phase:
Release pressure and keep edges in contact with heating plate for time t2
Note: When releasing pressure, edges must remain in contact with heating plate. In case this doesn't happen, it is
necessary to repeat the weld from the start.
3. Removing heating element:

Remove heating plate in max time t3, without damaging edges to be fused.
4. Reaching welding force:

Bring edges into contact, slowly increasing pressure until reaching pressure F5, in time t4. Prevent melded material
from coming out suddendly and exceedingly.
5. Fusion welding phase:

Keep edges into contact for time t5.
6. Cooling:
Let the joint to cool down naturally without subjecting it to mechanical stress.
Do not use water or compressed air to accelerate cooling.

The joint should be protected against rain, wind and/or excessive sunlight.
Once the cooling phase is done, it is possible to remove the welded elements from the machine.

THERMOREGULATOR, TEMPERATURE
SETTING
Connect the heating element plug to the POWER SUPPLY

power supply.
The two leds A and B in the handle will

light on at the same time.
After about 10-20 minutes heating plate

will reach the working temperature and
the green led B will start flashing,
indicating that thermoregulator is going to
manage the incoming tension and keep
the set temperature.
Set the temperature to the correct value

according to the material and thickness
of pipes / fittings by rotating the screw C
with a screwdriver. Such value is
C
recomended by the pipes / fittings
manufacturer and must be observed.
B

WARNING!
The instant release of the handwheel 3 might
be cause of injuries for the user. Always take
care to slowly move the handwheel.
2. Heating phase
Slowly release the handwheel 3 to reset the

applied force, then keep the edge of pipes in
contact with the heating plate for the time t2. 3
Important:
Warning: do not separate the edges from the
heating plate. If that happens will be
necessary to repeat the welding operations all
over again.
