1. The device has been overheated. Wait a few minutes. After the
diode goes out, continue welding.
Unsatisfactory weld quality
when MMA welding, the
electrode sticks to the
material being welded
1. Check the polarity of the welding cable connection
2. Check that the electrode is not wet. Replace the electrode.
3. The welder is powered by a power generator or by a long
extension cord with too small cable cross section. Connect the
device directly to the mains
Unsatisfactory
weld
quality for TIG welding
1. Replace consumable parts. Change the tungsten electrode or gas
cylinder for higher quality materials
2. Check that the shielding gas flows with the right intensity
3. Check gas supply hose, improve hose connection with fittings and
condition of quick couplings
4. Check the bench gear reducer.
9. OPERATING INSTRUCTIONS
The machine should be operated in an atmosphere free of corrosive components and high dustiness. Do not
place the device in dusty places, near working grinders, etc. Dusting and contamination with metal chips of
control boards, wires and connections inside the device may lead to electric short circuit and, as a
consequence, damage to the welder.
Avoid operating in environments with high humidity, especially in situations of dew on metal components.
In the event of dew on metal parts, e.g. after placing a cool device in a warm room, wait until the dew has
disappeared. It is recommended to place the welding machine under a roof to protect against adverse weather
conditions when using the welder outdoors.
The machine should be used in the following conditions:
-
changes in the effective value of the supply voltage not more than 10%
-
ambient temperature from –10 ° C to + 40 ° C
-
atmospheric pressure 860 to 1060 hPa
-
relative atmospheric humidity not more than 80%
-
altitude up to 1000m
10.MAINTENANCE INSTRUCTIONS
As part of daily service, keep the welding machine clean, check the condition of external connections and the
condition of electric wires and cables.
Replace consumable parts regularly.
Periodically clean the inside of the machine by blowing compressed air to remove dust and metal filings from
the control boards as well as the wiring and electrical connections.
A general inspection and condition of the electrical connections should be carried out at least once every six
months, in particular:
-
status of electric shock protection
- insulation condition
- security system status
- proper functioning of the cooling system
Damage resulting from operating the welding machine in improper conditions and failure to comply
with maintenance instructions are not covered by warranty repairs.
STORAGE AND TRANSPORT INSTRUCTIONS
The device should be stored at -10
°
C to + 40
°
C and relative humidity up to 80% free of corrosive fumes
and dust. Packaged equipment should be transported using covered means of transport. During transport,
the packed device must be secured against slipping and positioned correctly.
