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.
Specific instructions for the PROGRESS 2021K model.
This equipment has an advanced control panel with 8 LEDs, a 3x7
segment display, two buttons and an adjustment knob. The parame-
ters are selected with the two lower buttons marked with a triangle.
The left button selects the left parameters and the right the thickness
of the electrode to be used. The specific value of the parameter is
adjusted with the center knob.
Controls description:
Hot Start:
Indicates on the display the value from 0 to 100. It is used
to regulate the ignition current in the arc. Set value 0 when using
TIG.
Arc Force:
Indicates the value from 0 to 100 on the display. It is
used to adjust the best response depending on the type of electrode.
As a general rule, select low values for Rutile-type electrodes. (ej:
E6013), medium values for basic electrode (eg E7018) and high va
-
lues for cellulosic electrodes (eg E6011).
Set value 0 when using TIG
VRD On/Off:
Press and hold the left button for 2 seconds to change
this value.
Low vacuum welding voltage is mandatory for certain jobs. Consult
your manager or site manager.
If so, set VRD (Voltage Reduction Device) to ON.
If it is not required, it is recommended to select VRD in OFF since the
electrode priming is of superior quality thanks to the higher voltage
in no-load.
Led diameters MMA:
Selection of the thickness of the electrode to
be used and limits the current values, if no LED is on, the current can
be selected from 20 to 200 amps.

Using the LIFT TIG
This equipment has a synergic system, it is not necessary to select
TIG welding, simply connect a system (not supplied, consult your
Stayer dealer) consisting of a TIG torch with gas regulation by valve,
1/2 ”DINSE power connection and gas connection compatible with a
supply of technical protective gas, normally pure Argon. To start the
arc it is not necessary to scrape (and contaminate the part) simply
touch the part with the tungsten electrode and lift 3mm to comforta-
bly start the arc. Take into account leaving Hot Start and Arc Force
values at “0”.
