Sets the main welding current . Unit(A) and setting range (5-200A).
Base current setting indicator (5)
Only available when pulse mode (12) is selected. Sets the current of the low/ base pulse. Unit(A)
and setting range (5-200A).
Down slope setting indicator (6)
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. Unit(S) and setting range (0-10S).
End current setting indicator (7)
Available in 4T trigger mode, sets a welding current 5-100% of the main welding current activat-
ed when the trigger is held on to ‘unlatch’ the trigger before the weld is finished. If downslope (6)
is set, the current will go through the downslope period before going to the end current set. When
the trigger is released, the arc will stop.
Post gas flow setting indicator (8)
Controls the period of time the shielding gas continues 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. Unit(S) and setting range (0-10S).
Pulse width setting indicator (9)
Only available when pulse mode (12) is selected. Sets the time proportion as a percentage
between the peak current and base current when using pulse mode. Neutral setting is 50%, the
time period of the peak current and base current pulse is equal. Higher pulse duty setting will give
greater heat input, while lower pulse duty will have the opposite effect. Unit(%) and setting range
(5-95%).
Pulse frequency setting indicator (10)
Only available when pulse mode (12) is selected. Sets the rate that the welding output alternates
between the peak and base current settings. Unit(Hz) and setting range (0.5-200Hz).
Pulse welding
Pulse welding mode switches the welding output between a high and low current output in a
cyclical manner. When used correctly this function has substantial benefits in the TIG welding
