ADVANCETIG 200
Further Controls Explained
TIG HF/ Lift Ignition Modes (7,8)
For TIG welding process, contact of the torch tung-
sten to the workpiece will cause contamination of the
tungsten and the workpiece that will adversely affect
the weld quality, especially when the tungsten is elec-
trically energised.
HF Ignition
(High Frequency) sends a pulse of high
energy electricity through the torch system that is
capable of ‘jumping’ between the tungsten and the
workpiece, ensuring arc starting without any contact
between the tungsten and workpiece. The disadvan-
tage of HF ignition is that the high energy electrical
pulse creates significant electrical and radio signal
interference, which limits its use around sensitive
electronic equipment such as computers.
Lift TIG Ignition
is a compromise that minimises tung-
sten contamination while eliminating the electrical in-
terference of HF start systems. Lift arc starting works
by lightly resting the tungsten on the work piece, ac-
tivating the torch trigger signal and then lifting the
tungsten off. The control circuit will sense when the
tungsten is removed from the work piece and send
a low powered pulse of electricity through the tung-
sten that will cause the TIG arc to initiate. Because
the tungsten is not ‘live’ when it is in contact with the
work, contamination is minimised.
TIG 2T/4T Trigger Control (9)
2T mode the trigger is pulled and held on to activate
the welding circuit, when the trigger is released, the
welding circuit stops. 4T is known as ’latching’ mode.
The trigger is pulled once and released to activate the
welding circuit, pulled and released again to stops the
welding circuit. This function is useful to longer welds
as the trigger is not required to be held on continu-
ously. The ADVANCETIG 200 also has more advanced
current controls that can be used in 4T mode.
Overload/ Error Indicator (14)
Lights when over voltage, over current or electrical-
overheating (due to exceeding duty cycle) is detected
and protection is activated. When protection is acti-
vated, welding output will be disabled until the safety
system senses the overload has reduced sufficiently
and indicator lamp goes out. May also trigger if ma-
chine experiences an internal power circuit failure.
LCD Digital Multifunction Display (15)
Before welding displays the setting selected/being
adjusted using the control knob (19). During weld-
ing, displays welding current. The parameter setting
displayed is indicated by the LEDs 12,13,14,16,17,18.
If left inactive for several seconds, display will revert
back to main welding current setting.
Parameter Select/ Adjust Knob (19)
Switch between welding parameter settings by press-
ing this knob, adjust by turning the knob. Value of the
parameter selected will be shown on the LCD display
(15).
Post Flow Gas (20)
Controls the period of time the shielding gas contin-
ues to flow for after the arc is stopped. This protects
the weld area and torch tungsten from contamination
while it is still hot enough to react with atmospheric
gases, after the weld is finished.
Down Slope (22)
When the trigger is released, the welding current will
reduce gradually over the time selected down to 0.
This allows the operator to complete the weld without
leaving a ‘crater’ at the end of the weld pool.
Pre Flow (28)
Controls the period shielding gas will flow for when
the torch is triggered before the arc starts. This purg-
es the work area of atmospheric gas which could con-
taminate the weld before the weld starts.
Up Slope (30)
When the trigger is activated, the welding current will
increase gradually over the time selected up to the set
main welding current (31).
