START-UP
A. Unpacking
Unpack all items from the package and ensure that all items, specified within the scope
of the delivery are present.
B. Work environment
It is necessary to ensure well ventilation within the working area. The device is cooled
by the fan which ensures cooling for all internal subassemblies of the device. (Tip! The
guards must be installed in such way that the vent holes could be located at the front
side of the device) In order to leave some space for cleaning and cooling, the device
should be located within the distance of at least 15 cm (from each side) from other
objects. If the device is not efficiently cooled, the make-time decreases.
C. Conduits connection
Each device is equipped with feeder cable which supplies it with electric voltage. If the
device is connected to the current source with the voltage exceeding supply rated
voltage or improper phase is connect, it may result in serious damage of the machine.
The device which has been damages in such course does not subject to repair under
the warranty terms.
D. WIG-WELDING
The handle has to be take by the hand. Unto the black closing cap. Next, it is necessary
to insert wolframic electrode into the collet. Next put the housing onto the collet and
tighten the holder head (Nozzle).
INSTRUCTION OF OPERATION
TIG-welding
Clearing the station before welding.
MMA:
1 –MMA electrode holder
2 – workpiece
3 – mass clamp
EN
The TIG-welding is very sensitive about the surface (which is to be welded)
contamination. For this reason, before welding you have to remove rests of paints and
greases as well as the oxidized layer from the surface which will be welded.
DC TIG-welding
•
Connect the gas hose to the gas to welder supply socket.
•
Connect the gas hose to the welding gun and to the argon supply (to the gun) socket.
•
Connect weld piece to the mass clamp in welder, outlet (+).
•
Connect the welding handle plug to the arc and argon control rod.
Gas test:
Check the connection of the electric supply and switch on the voltage.
Open the valve (regulator) of bottle with argon and switch on flow meter. Gun switch-
key has to be pressed and you have to select an appropriate gas flow. The inflow switch-key
has to be released and the gas inflow will be automatically stopped after several seconds. In
case of using the high frequency ignition, the wolframic electrode has to be retracted 2-3
mm from the weld piece. Next, after switching on the switch-key, the arc will be triggered.
The switch off will result in the reduction of electric current intensity and the arc will no
longer be active. The blowing shaft can not decay before the electric arc switch off. Gas
must cool down the fusion weld as it will not become oxidized. After finishing the welding
process, you have to switch off the argon supply button on the bottle and the welder supply.
Pulling the electric supply plug when the electric supply switch is on is prohibited.
Manual welding with the electrode
•
Connect the E-Hand conduit to the negative pole (-).
•
Set the current intensity regulator at the proper intensity (the impulse current
intensity regulator is in lower position). Select current in accordance with empirical
formula: I=40d, where d is the electrode diameter.
•
Positive and negative connection during the welding process.
•
The welder has to be connected to the electric supply socket and turn main switch
on. The control lamp will light.
•
It is necessary to bring the attention to the relative intensity of welding current
and the relative welder’s make-time.
•
The overloading may result in damages. You can avoid this.
•
After finishing the device operation, it is necessary to leave the device for cooling
and then – switch off the supply.
MAINTENANCE
The gun has to be checked for wear, cracks or bare conduits. All worn elements have to
be repaired or replaced before next operation of the device. Strongly worn gun nozzle
may result in the decrease of welding speed, voltage drop and uneven material cutting
line. The gun nozzle strongly worn symptom is the extended or too big hole. External
part of the electrode should not be located deeper than 3.2 mm. Check the screw
thread if there is problem with tightening protective cap.
WEEKLY MAINTENANCE
Check if the room ventilation works properly.
