WELDING PROCESS: DESCRIPTION OF
CONTROLS AND SIGNALS
Once you have put the welding machine into operation,
switch it on and apply the required adjustments.
Adjusting the welding current
Select the welding current depending on the electrode type, joint and
welding position.
Indicatively, the different currents to be used with the different
electrode diameters, are listed in Fig. 4.
To strike the welding arc with the coated electrode, brush it onto the
piece to be welded and, as soon as the arc is struck, constantly hold
it at a distance equal to the electrode diameter and at an angle of
approximately 20º – 30º in the direction in which you are welding.
To strike the welding arc with the TIG torch, make sure the protection
gas valve is open. With a rapid, confident move, touch and then take
away the electrode point from the piece to be welded.
Heating stop indication
If the warning light is switched on (or see "HEA" in the display),
means that the thermal protection is already on.
If the duty cycle "X" shown on the data plate is exceeded, a thermal
cutout stops the machine before any damage is caused. Wait for the
operation to be restored and, if possible, wait for a few minutes more
until the gear factor is complied.
If the thermal protection is continuously on, means that the machine
is overworking.
"Hot start"
The welding machine is fitted with an automatic device that
facilitates the striking of the arc, increasing the current only at that
very moment.
"Antisticking"
The welding machine is fitted with an automatic device that interrupts
the current for a few seconds after having detected that the electrode
has tuck to the piece to be welded. By doing so, the electrode will
not overheat.
PROGRESS 1600 Additional instructions.
This equipment has an advanced control panel formed by 8 LEDs, a
3x7 segment display, two buttons and an adjustment knob.
Parameters are selected with the two lower buttons marked with a
triangle.
The left button selects the left parameters and the right button
selects the right ones.
The selection is made in a circular move, so the selected parameter
is indicated by a led light.
The specific value of the parameter is adjusted with the center knob.
Left side controls description
Led Current: When the display is on, it indicates the configured
welding amps.
Led Arc Force: Indicates on the display a value from 0 to 10- It is
used to adapt the best response depending on the type of electrode.
As a general rule, select low values for rutile electrodes (ex: E6013),
average values for basic electrodes (ex: E7018) and high values for
cellulosic electrodes (ex: E6011).
Led VRD ON/OFF: For certain jobs, a low voltage for vacuum-brazing
process is mandatory. Consult your manager or site manager. If
so, turn VRD (voltage reduction device) ON. If not required, it is
recommended to keep VRD switched OFF, as the electrode priming
will have a superior quality due to the higher no-load voltage.
MMA Led: Indicates equipment configured to weld coated electrodes.
LIFT TIG Led: Indicates that the equipment is set for TIG welding
with lift-arc ignition. In order to weld TIG, you will need a system (not
supplied along this machine; consult your Stayer supplier) consisting
of a TIG torch with a gas regulation valve, a 3/8" DINSE power
connection and gas connection suitable for a supply of technical
protective gas, normally pure argon. To start the arc is not necessary
to scrape (and contaminate the workpiece), simply touch the part
with the tungsten electrode and lift 3mm to comfortably start the arc.
Right side settings: Determined by the type of welding process
(MMA/TIG) and the electrode to be used. Once those parameters
have been selected, a correct range of use is set for any of the three
diameter selections. If you need a more delicate adjustment of the
welding current, use the central knob.
RECOMMENDATIONS FOR USE
- Only use an electrical extension cord when absolutely necessary,
and providing it has an equal or larger section to the power cable and
is fitted with a grounding conductor.
- Do not block the welder air intakes. Do not store the welder in
containers or on shelving that does not guarantee a suitable
ventilation.
- Do not use the welder in any environment where in presence of
gas, vapors, conductive powders (e.g: iron shavings), brackish air,
caustic fumes or other agents that could damage the metal parts and
the electrical insulation.
The electric parts of the welder have been treated with protective
resins. When used for the first time, smoke may be noticed; this is
caused by the resin drying out completely.
The smoke should only last for a few minutes.
MAINTENANCE
Switch off the welder and remove the plug from the power socket
before carrying out any maintenance operation.
Extraordinary maintenance of the machine must be periodically
carried out by expert staff or qualified electrical mechanics,
depending on the use.
- Inspect the inside of the welder and remove any deposited dust on
the electrical parts (by using compressed air), and in the electronic
cards (using a very soft brush and appropriate cleaning products).
- Check that the electrical connections are tight and the insulation on
the wiring is not damaged.
