INSTRUCTION OF OPERATION
TIG-welding
The TIG-welding is very sensitive about the surface (which is to be welded) contami-
nation. 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 frequen-
cy 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 prohi-
bited.
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 empiri-
cal 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.
MIG/MAG welding
Please install the items in the order shown. Pay attention to the proper arrangement
of the elements as shown in the pictures. The device is not operational yet. Open the
gas flow at a pressure of 5-7 l/min. Protect the gas outlet against gusts of wind. Also
note the following: The first stages of the current controller are used for welding thin
metal sheets and the next stages are used for thicker walls. With each operation of
the switch the wire feed speed should also be adjusted. If a drop is formed at the end
of the welding wire while welding, the wire feed speed has to be increased; however if
it can be felt as the wire presses against the hose bundle, the speed has to be redu-
ced. Always use tongs to move the parts that have just been welded and to remove
encrustations at the end of the burner, as these elements are very hot. Once the arc
is ignited keep the hose bundle at an angle of about 30 degrees vertically.

WEEKLY MAINTENANCE

Check if the room ventilation works properly.
