4.2.2 TIG welding parameters description
Gas bottle symbol
–
Adjustment of a shield gas supply before arc ignition
lp
– Start amps. Start current lasts while welding pool creates than it ramps up to welding current.
tn
– Current ramping time. Setting the time it takes for start current to reach welding current value.
lb
– Base current when welding with pulse. Lower value of pulse amperage.
Is
– Welding current. Upper value of pulse amperage when welding with pulse.
Puls bal.
– Pulse balance
.
Adjustment of a base current (Ib) to welding current (Is) ratio. 50% setting
means that base current lasts for the same time as welding current.
Puls Hz
– Adjustment of a TIG pulse frequency.
AC balans
– Adjustment of a positive to negative polarization when welding with AC/DC current.
AC Hz
– Alternating current frequency. Number of cycles per seconds.
to
– Time it takes from welding current to decrease to end current.
Ik
– End current. Adjustment of a current it takes to fill out the crater before arc goes off.
Gas bottle symbol 2
–
Adjustment of a time when shield gas is provided after arc stops.
4.2.3
Bi-Level feature description
Bi-Level is active only when the pulse welding is off. This feature allows to switch between previously
provided welding current values (
Ib
and
Is
). It it mostly used when welding material with various
thickness or when there is a need to use two different amperage values without putting the arc off.
To use the feature first pulse welding must be put to off. Than using the torch control mode button select
Bi-Level. it is described with an
r
symbol and a value from 2 to 10 seconds. It is the time you need to
press the button to terminate welding. After the feature is activated the welding current Ib and Is can be
provided.
To conduct welding hold the button on the torch handle until arc ignites. While you hold the button the
device keeps the base current (
Ib
). To switch between previously provided amperage values release
the button. Afterwards the device sets the second provided amperage which is welding current (
Is
). If
you want to switch back to the previous amperage value (
Ib
) you need to quickly press and release
the button. And again if you want to switch between the values you need to press and release the button.
To terminate the welding press and hold the button for the time previously selected (
r
).
