9.3. initiation arc
Initiation arc welding coated electrode is to touch the electrode to the workpiece, and short rubbed isolation. For initiation of the arc electrode wherein
the sheath forms a non-conductive when solidified slag to be pre-clean the tip of the electrode by repeatedly impact against a hard surface until the
metal in contact with the work piece.
10. TIG welding
MMA welder 200 allows TIG welding using an additional TIG torch. The handle is required gas-cooled current-carrying capacity of 190A, equipped with
a flow control valve for the shielding gas and shielding gas cylinder. Arc ignition takes place by friction, in analogy to the MMA.
11. Before calling service,
In the event of malfunction of the unit, before sending welding for service, check the list of basic failures and try to remove them yourself.
Repair work may only be carried out after removing the plug from the wall socket.
Attention! The device is not sealed, and the user can remove the cover of the welding device in order to remove minor breakdowns.
symptoms
Remedy
The power indicator is not lit, the fan does
not work, no output
1. Remove the casing and check the connection of all electrical plug inside the device
2. Make sure the switch is in the ON position
3. Check the security on the network connection and
Power light is on, the fan does not
work, no output voltage.
1. Remove the casing and check the connection of all electrical plug inside the device
2. Check if the device has not been connected to the higher voltage. If so, connect to 230V
and turn again
3. The supply voltage is unstable and turns on the overvoltage protection. Turn off device for
2-3 minutes and then back
4. Short switching on and off switch may have been activated overvoltage protection.
Turn off device for 2-3 minutes and then back
Power light is on, the fan is running,
no welder strikes the arc
1. Check the correct terminals and the electrical conductivity of the electrode wire
and the mass
Power light is on, the fan works, light
is overheating
1. The device is overheated. Wait a few minutes until the LED goes out and continue welding.
Unsatisfactory quality of the weld, the
electrode sticks to the work piece
1. Check the polarity of the welding wire
2. Check that the electrode is not wet. Replace the electrode.
3. The welder is supplied from the generator or by a long extension cord diameter is
too small cable. Connect directly to the mains
12. OPERATION MANUAL
Operation of the device 200 MMA should take place in an atmosphere free of corrosive components and dusty. Do not place the device in dusty,
near the working grinders, etc. Dust and pollution control boards metallic filings, wires and connections inside the unit may cause an electrical
short, and consequently damage to the welding machine.
