5.2 Function explanation
5.2.1 2--stroke mode
Set the 2--stroke mode by means of the knob (3). Set required wire speed by means
of the knob (2). The creep speed option can be set by means of the knob (6). If
creep speed is chosen the wire speed before the actual start of welding is reduced
by two. The creep speed is not recommended for speed setting close to the minimal.
The burn--back time should set by means of the knob (4). This setting should be
chosen experimentally, starting from the lowest values.
Pressing the torch switch opens the gas valve and then switching the power source
on and feeding the wire. Releasing the torch switch stops the wire feeding. After
delay proportional to burn--back time setting the power is switched off. Eventually
the gas is cut off too.
5.2.2 4--stroke mode
Set the 4--stroke mode by means of the knob (3). Other settings as for 2--stroke
mode.
This mode could be described as follows:
1. switch pressed -- gas starts to flow,
2. switch released -- power source is switched and wire is fed, the actual start of
welding,
3. switched pressed again -- stop of welding, gas remains flowing,
4. switch released -- cut off the gas.
5.2.3 Burnback time
Burnback time is a delay between the time when the wire starts to brake until the
time when the power source switches off the welding voltage. Too short burnback
time results in a long wire stickout after completion of welding, with a risk of the wire
being caught in the weld pool. Too long a burnback time results in a shorter stickout,
with increased risk of the arc striking back to the contact tip.
5.2.4 Creep start
Creep start means that the wire is fed at reduced speed within 1 sec after welding
torch trigger is pressed, and then the speed increases to the set speed.
5.2.5 Inching and gas purge modes
Set the required mode by means of the knob (3). Inching or gas purge is started by
means of the torch switch.
5.2.6 Wire feed speed
This sets the required feed speed of the filler wire in m/minute.
5.2.7 Spot welding
Set the spot welding mode by means of the knob (3). Set the required time of the
spot welding by means of the knob (5). Other settings as for previously described
modes. The control sequence is similar to 2--stroke mode sequence. The difference
is that the welding is stopped automatically after particular time. The torch switch
must be pressed up to the end of welding. Releasing the torch switch enables the
next spot welding cycle.
