Gas pre-flow
Gas pre-flow is the period of time for
which gas flows after torch trigger is
pressed and before the HF arc is
established or until the torch is lifted away
from the workpiece in the LIFTIG
process. The time can be set to 0.1 to 5.0
Sec. The time can be adjusted by pressing the
keypad and simultaneously turning the large control
knob.
Slope-down
When welding is stopped by
activation of the trigger the machine
enters into slope-down. During this
period the current is decreased to the
final current. The length of this period
is the slope-down period, which is
indicated in seconds from 0-16 Sec.
Gas post-flow
The gas post-flow time is the period from
the extinction of the arc to the interruption
of the gas supply. The time is indicated in
seconds from 3-25 Sec. The time can be
adjusted by pressing the keypad and
simultaneously turning the large control
knob.
Torch control
Adjustment is made by means of the adjustment
button on the welding torch if such one exits. The
maximum welding current is adjusted on the button
on the machine control panel. By means of the torch
adjustment it is it is possible to decrease the current
to the minimum current of the machine.
Advanced functions
The machine has advanced
functions that can be adjusted in
order to optimise the use of the
machine. Pressing the keypad for ignition method
until the display changes to text can open the
functions. The large control knob should be turned
until the required parameter is shown in the display.
Thereafter the keypad for ignition method should be
pressed shortly and the parameter can be adjusted
by means of the large control knob. The keypad for
ignition method should be pressed again to save the
changes in the internal memory. Other parameters
can be selected by means of the large control knob or
a short press on another keypad than the keypad for
ignition method will close the menu.
The machine has the following advanced functions:
A
StA Start amp (TIG)
B Sto Stop amp (TIG)
C US Slope up (TIG)
D LC Base current (TIG pulse)
E Fr Pulse frequency (TIG pulse)
F rAt Pulse time (TIG puls)
G Hot Hot start time (MMA)
H AC Reset of all settings
Start amp (TIG)
Is adjusted from 3 A to the maximum welding current.
If the selected start amp is lower than 3 A, the start
amp will be 50% of the welding current. If the start
amp is higher than the maximum welding current the
start amp will be the same as the welding current.
Original setting: 50%
Stop amp (TIG)
Can be adjusted from 3 A to the maximum welding
current. If the selected stop amp is higher than the
maximum welding current the stop amp will be similar
to the adjusted welding current.
Original setting: 3A
- Slope up (TIG)
Can be adjusted from 0.1 to 2.55 Sec.
Original setting: 0.1 Sec.
- Base current (TIG)
Can be adjusted from 20 to 100% of the selected
pulse current.
Original setting: 60%
- Pulse frequency (TIG)
Can be adjusted from 0.2 to 50 Hz (pulses per
second). Original setting: 2.5 Hz.
- Pulse time / base amp time (TIG)
Can be adjusted from 20 to 100%.
Original setting: 40%
- Hot start time (MMA)
Can adjusted from 0.0 to 5.0 Sec.
The hot start current is 20% above the welding
current.
Original setting: 0.0 Sec.
Fixed functions
A number of functions are fixed and cannot be
connected or disconnected from the control panel.
- Anti-freeze
- Arc power
Antifreeze
The antifreeze function is always active. When
welding MMA or TIG it may occur that the electrode
sticks to the work piece. The machine will register
that the electrode sticks and it will then decrease the
welding current to 12 A which make it easy to break
the electrode off the work piece. Welding can then be
restarted as usual.
Arc Power
Arc power is an arc enhancing function used to
stabilize the arc in electrode welding. This is done by
increasing the welding current during the short
circuits. The additional current disappears when there
is no longer a short circuit. The function is optimized
to a large amount of rutile and basic electrodes.
