8.0 WELDING PROGRAMS MANAGEMENT
The welding and the relative parameters set up can be done manually through var-
ious commands.
When first switched on the generator is set up in a predefined state and with weld-
ing parameters value that allows to work immediately.
Moreover, the generator is provided with a memory that saves the set up config-
uration for each welding mode (MMA, TIG HF, TIG Lift) before it is turn off.
Therefore, the worker will be able to see the last set up when the generator is
switched on again.
9.0 THE USE OF THE REMOTE CONTROL
CAUTION: PRESSING VERTICAL SCROLL KEY (Ref. 14 - Fig. 1 page 3) WHEN
THE REMOTE CONTROL IS NOT CONNECTED HAS NO EFFECT.
In electrode welding mode, after activating the remote function you can adjust
welding current continuously from minimum to maximum using the remote con-
trol. The display will show the current set with the control.
NOTE: IN ELECTRODE MODE YOU CAN SELECT MANUAL REMOTE
CONTROL ONLY
In TIG welding mode you can select between two different remote controls:
1.
Manual Remote Control:
nation with remote controls or RC-type torches, i.e. equipped with a knob or
slider to regulate current remotely. The welding current will be adjustable
11.0 TYPES OF MALFUNCTIONING/ WELDING FAULTS – CAUSES – REMEDIES
TYPES OF MALFUNCTIONING
WELDING FAULTS
The generator does not weld: the digital switch is not
lit.
During welding suddenly the outgoing current is
interrupted, the the orange led goes on.
Welding power reduced.
Excessive jets.
Craters.
Inclusions.
Inadequate penetration.
Sticking.
Blowing and porosity.
Jacks.
The electrode fuses in TIG.
WELDING PROGRAMS MANAGEMENT
The power source allows the use of the remote con-
trols. After connecting the remote control to the
female connector on the front of the machine you can
choose whether to work in local or remote mode by
means of vertical scroll key (Ref. 14 - Fig. 1 page 3) .
this mode is especially useful in combi-
POSSIBLE CAUSES
A) The main switch is off.
B) The power lead is interrupted (lack of one or two
phases).
C) Other.
Overheating has occurred and the automatic protec-
tion has come on. (See work cycles).
Outgoing wires are not correctly attached.
A phase is missing.
Welding arch too long.
Welding current too high.
Fast removal of the electrodes.
Inadequate cleaning and bad distribution of coating.
Faulty movement of the electrodes.
Forward speed too high. Welding current too low.
Welding arch too short.
Current too low.
Damp electrodes. Arch too long. Wrong torch pola-
rity.
Currents too high. Dirty materials.
Wrong torch polarity. Type of gas not suitable.
continuously from minimum to maximum. To use this peripheral device
properly and comfortably selection of "four stroke" mode is recommended.
2.
Pedal-Operated Remote Control:
combination with pedals equipped with a microswitch with a trigger func-
tion. This selection involves inhibition of the up and down slopes. Welding
current can be adjusted with the pedal between the minimum value and the
panel setting.
The microswitch in the control pedal means you can start welding by simply
pressing the pedal, i.e. without using the TIG torch button. To use this peri-
pheral device properly and comfortably selection of "four stroke" mode is
recommended.
NOTE: IN THIS MODE, WHEN THE WELDING PROCESS IS NOT ACTIVE, USING
THE REMOTE CONTROL (PEDAL) WILL PRODUCE NO CHANGE IN THE CURRENT
INDICATED ON THE DISPLAY.
10.0 MAINTENANCE
IMPORTANT: Disconnect the power plug and wait at least 5 minutes
before carrying out any maintenance. Maintenance must be carried out more fre-
quently in heavy operating conditions.
Carry out the following operations every three (3) months:
a.
Replace any illegible labels.
b.
Clean and tighten the welding terminals.
c.
Replace damaged gas tubing.
d.
Repair or replace damaged welding cables.
e.
Have specialized personnel replace the power cable if damaged.
Carry out the following operations every six (6) months:
Remove any dust inside the generator using a jet of dry air.
Carry out this operation more frequently when working in very dusty places.
CONTROLS AND REMEDIES
A) Switch on mains.
B) Verify and repair.
C) Ask for the intervention of the Assistance Centre.
Keep generator switched on and wait till temperature has
dropped again (10-15 minutes) to the point where the
orange switch goes off again.
Check that wires are intact, that the pliers are sufficient and
that they are applied to welding surface clean from rust,
paint or oils.
Wrong torch polarity, lower the current values.
Increase current values.
