Connecting Gas - STAMOS S-MIG 250P Manual De Instrucciones

PLEASE NOTE! THE DEVICE MAY ONLY BE USED UPON
CONNECTION TO AN INSTALLMENT WITH A PROPERLY
FUNCTIONING FUSE.

4.3.2 CONNECTING GAS

• Gas tanks must be placed far from the welded object
and be protected against falling.
• Gas connector of the welder must be connected with
the tank or gas installation by means of the correct
pipe and regulator with gas flow regulation. Please
note! Connection of line regulators to the tank and
the other way round is prohibited. Such a change can
result in regulator damage and serious injuries.
• Economical gas use extends the welding time.

3. Overload / fault LED indicator:
a) if the machine has malfunctioned and cannot be
operated.
b) if the cutting device has exceeded the standard
working time the protection mode is initiated and the
machine will stop functioning. This means that the
machine is now being cooled in order to be able to
restore temperature control again after the device has
overheated. Therefore the machine is stopped. During
this process, the red warning light on the front panel
lights up. In this case it is not necessary to remove the
power plug from the socket. The ventilation system
may be left on in order to enhance the cooling of the
machine. When the red light goes dark, this means
that the temperature is now down to the normal level
and the unit can be put back into operation.

the metal welding/cutting process, release this button
to end this process. 4T – press this button on the
burner to start the metal welding/cutting process,
releasing this button does not end this process.
Press and release this button again to end the metal
welding/cutting process).

12. Grounding:
at the back of each welder there is a screw and a label
to provide the necessary grounding. Before operating
the unit it is necessary to ground the shell of the
welding apparatus by means of a cable with cross-
section not less than 6 mm.

5.1. PREPARING THE DEVICE FOR USE / DEVICE USE
Each unit is equipped with a main power cable, which
is responsible for providing current and voltage to the
device. If the device is connected to power which exceeds
the required voltage, or if the wrong phase is set, it may
lead to severe damage to the unit. This is not covered
by the warranty for the equipment and the user will be
responsible for such situations.

5.2. INSTALLATION OF THE WIRE COIL AND INSERTING
THE WIRE
1. Open the left side door of the welder by pulling the
lever.
2. Please observe the size of the coil holder. The size
must match the diameter of the coil. Place the coil
on the rack.
3. Next pull out the wire clockwise. The beginning of
the wire is usually fixed to the coil, so that the wire
can not be separated from the coil. Use a standard
coil. The size of the holder is in accordance with the
standard.
4. Loosen the anchor bolt on the coil holder. Then
place the coil on the rack. Attach the anchor bolt
and tighten it so that the wire can not slip off. Please
remember not to attach this element too tightly, as it
might negatively impact the welding effectiveness of
the device. Please keep the end of the wire straight
and free of burrs.
5. Open the rotary knob
6. Raise the pressure element.

7. Check that the grooves on the wire feed roll match the
wire diameter, if necessary remove the fixing of the
wire coil by loosening the screws.
8. Now lower the pressure element and tighten the knob
until the wire runs evenly on the rolls. If the wire slips
on the rolls, tighten the knob further.
Caution: Do not tighten the element too much, as
excessive pressure on the rolls may damage the wire
feed motor.
9. Switch on the welding device. (ON/OFF switch)
10. After making sure that all security measures have
been taken, proceed as follows, depending on the
model:
In the case of S-MIG250P and S-MIG250 the gas and
power nozzle have to be removed from the hose
bundle and the current controller along with wire feed
speed regulator should be put on Stage 1. Now hold
the INCHING switch until the wire slides out from the
tip of the hose bundle. Then put the power and gas
nozzle back on.
11. Set the required volume of gas at the valve of the gas
cylinder.
Tip: (0.6 mm wire > 6 l/h), (0.8 mm wire > 8 l/h), (1.0
mm wire > 10 l/h).
