Slow pulse
(TIG DC and TIG AC)
Is used for selection of slow pulse. The
pulse current is equal to the set current. It is possible to
adjust:
Pulse time
Adjustable from 0.01 to 10 sec. in DC and from 0.1
to 10 sec. in AC, in steps of 0.01 sec.
Pause time
Adjustable from 0.01 to 10 sec. in DC and from 0.1
to 10 sec. in AC, in steps of 0.01 sec.
Base amp
Adjustable from 10 to 90% of the pulse current.
Fast pulse
Is used for selection of fast pulse. The
pulse current is equal to the set
current. It is possible to adjust:
Pulse frequency
This function is only possible to adjust in DC welding.
Variable 25-523 Hz.
Base amp
Adjustable from 10 to 90% of the pulse current.
TM
Synergy PLUS
The machines automatically and dynamically adjust
all overall pulse parameters during welding, when
the peak welding current has been set by encoder.
TIG tack welding TIG-A-TACK
The machine offers one tack welding function in the
individual program to allow quick switch-over from
welding to tack welding. In TIG DC and AC the following
features will be available:
Arc ignition HF 2-times
-
No slope-up/slope-down
-
No pulse
-
Reuse of pre-gas/post-gas values from the current
-
program
Spot TIME from 0.01 to 2.5 secs in steps of 0.01 sec.
-
Set the value by selecting the parameter "spot time"
.
Electrode welding (MMA)
Is used for selection of electrode
welding. It is not possible to change
welding process during welding.
(only TIG DC)
TM
Hot start
Hot start is a function that helps to establish the arc
at the beginning of MMA welding. This can be
achieved by increasing welding current (when the electrode
is applied to the workpiece) in relation to the set value. This
increased start amp is maintained for half a second, after
which it decreases to the set value of welding current.

Welding
start
The hot start value reflects the percentage value by which
initial current is increased, and can be set between 0% and
100%.
Arc-power
The arc power function is used to stabilise the arc in
MMA welding. This can be acheived by increasing
welding current during the short-circuits. The additional
current ceases when the short circuit is no longer present.
Amp
Set w elding
current
Arc power can be adjusted between 0 and 100% of the
welding current setting.
E.g.
If the welding current is set to 40A and arc power to 50% the
additional current is 20 A equals 60 A when doing arc power.
If the arc power is set to 100% the additional current is 40 A
equals 80 A when doing arc power.
Torch adjustment /
remote control – 7-poled plug
The regulation of welding current is made by means
of the torch potentiometer (optional). The maximum current
reachable is the level previously adjusted on the front panel.
The minimum current is 5A.
External adjustment –
8-poled plug (optional)
Can be used for foot pedal (optional) and remote
control units (optional) that use a 8-poled plug. The function
is used for arc ignition and adjustment of the current. The
maximum current reachable is the level previously adjusted
on the front panel. The actual current is shown on the
display.
Start amp can be used as a setting of minimum current as a
percentage of maximum current.
Please note: The machine will automatically start in two-times in
this function when the machine uses a software version before
