POWER SUPPLY: 230/240 Volts (model also available in 115V +/- 15%) 50 –
60 Hz Power supply rated at 10 amps
The machine is supplied with a three-prong plug and is a waterproof unit.
START-UP
To start the machine, set the unit to the “on” position. Press the emergency
stop button to reset it. The machine will not work if these steps are not
performed.
Fill the pot with a solder bar, wire, or shot to a level between 1 and 2 mm
below the rim of the crucible.
Set the controller to the desired temperature (max. 450°C). Check that the
engine is off, then start the heater. Wait about 45 minutes for the solder to
melt. The motor can now be turned on and the potentiometer can turn. The port
speed is about 13 rpm. and the direction is clockwise.
Note: The motor drive is interlocked by the digital temperature
controller relay contacts (setpoint 2) so that the motor will only run when
the alloy is molten. Always set the regulator to a soldering temperature above
200°C.
Use the four adjustable feet located under the housing to level the solder
surface relative to the slag tray.
WELD MAINTENANCE
The pickup blade may require adjustment to ensure maximum removal of slag from
the surface of the tin.
A tray is fitted so that the slag can be swept to the outlet chute, which
leads to the collection bin. Avoid too-tight adjustment of the pickup blade so
as not to interfere with the rotation of the pot.
MAINTENANCE
If examination of the device is required, disconnect it from the mains.
Access can then be obtained by removing the thermocouple from its location and
the slide from the plate. After that, the entire pot can be removed.
If the belt tension needs adjustment, remove the L-shaped control panel and
adjust the motor mount. The belt should only be tight enough to drive the pot
otherwise the motor bearings could be damaged.
SPECIFICITIES
If the Rotadip is to be incorporated into specific equipment or installation,
care should be taken to ensure that there is sufficient ventilation to protect
the internal components from exposure to ambient temperatures above 50°C. This
is particularly valid for the high temperature (HT) Rotadip.
It may be necessary to incorporate a forced airflow into the machine to
protect the Rotadip.
During the IEE safety checks before use, it is advisable to operate the device
at a temperature of approximately 100-150°C for approximately 30 minutes to
remove moisture from the insulation of the element, which could distort the
reading of insulation-to-ground tests.
If an RC.B is installed in the electrical circuit, it may be necessary to
disconnect the ground from the machine during the warm-up period.
“Setpoint 2” is factory set and does not require any additional service
changes. The red light on the front of the controller turns off when the motor
circuit is live.
TINNING
RULES OF USE AND SAFETY
Welding and brazing are processes widely used in industry to join metals.
As with all manufacturing processes, a number of points must be considered to
ensure the success of the method and the safety of operating personnel.
RULES OF USE FOR TINNING
- The parts to be joined must be free of all surface contamination such as grease, oil, rust, paint, and other plating.
- The junction area must be fluxed before heating. Flux is a material that coats the metal during heating to prevent surface oxidation. It also contains chemicals that will clean the metal of light contamination to ensure good adhesion when joining alloy fluxes. There is a multitude of different fluxes available to suit various metal alloys and assemblies. Flux residues normally need to be removed after the weld is created, some dissolve in water and some require chemical or mechanical removal.
- The correct splice alloy to use depends on the strength required, the joining of metals, and the end use of the part.
- It is necessary to heat the part in order to melt the alloy. There is a very wide variety of heating methods and the right one to choose depends on the part, the production rate required, the type of work required and the method of processing, etc.
OPERATOR SAFETY
Brazing uses heat, chemicals, and various metal alloys. Care should be taken
when using Rotadip.
Appropriate safety equipment should be worn to avoid burns.
1 . Grounding
Make sure the machine is properly located and grounded.
2. Heater
Valid for devices such as soldering irons, heating plates, soldering pots,
etc.
Heat is produced by an electric current. Precautions must therefore be taken
to avoid burns. In the case of the solder pot, two additional dangers are
present.
2.1. Molten metal is present, so parts must be dry and flow limited before
dipping, as steam will immediately form and excess will cause the metal to
spray.
2.2. Small pots, in particular, should be secured to a workbench to prevent
them from being knocked over.
ALLOYS
Alloys may contain tin, lead, silver, and zinc. All of these metals tend to
oxidize and volatilize if overheated and the vapors should not be inhaled.
Therefore, areas, where brazing is in progress, should be equipped with air
extraction
FLUX
Solder fluxes may or may not be corrosive. The chemicals used vary widely, but
the non-corrosive is usually resin and alcohol-based. The vapors are not
pleasant but are rather harmless. Corrosive fluxes, however, are based on
acids and the vapors should not be inhaled. Many of these fluxes contain zinc
chloride and the fumes contain hydrochloric acid. Air filtration equipment is
therefore essential.
For silver soldering, the melting of alloys at low temperatures is based on
sodium fluoride, potassium, and lithium. If they do not give off fumes at the
prescribed working temperature, any overheating causes the formation of
vapors; it is therefore recommended to filter the air.
SUMMARY
Brazing equipment is not dangerous if it is used correctly and the usual
protective measures are observed by maintenance technicians, especially when
servicing units connected to the mains.
The alloys and fluxes used in the tinning process require heat and good
ventilation is highly recommended. Guarding may be required to protect the
operator from burns from hot parts, high-frequency burns, and mechanical
hazards associated with handling the equipment.
USING THE CONTROL BOX To increase the case temperature, press the right
button until the green indicator shows the desired set point.
To decrease the temperature, press the second button from the right until the
green indicator shows the desired set point.
The white indicator shows the actual temperature.
The green indicator shows the set point.
These are the only two buttons you should use, the other buttons are used to
set the programming which is set by the manufacturer for optimal use and which
are locked.
If you remove the locks and modify the programming, the controller will not
work properly and could void the warranty.
