4.5.1 Spot Time (7h)
This only applies when set to Spot Trigger mode. This Spot Timer setting is the time adjustment for the
welding duration and is adjustable from 0.01 – 10 seconds.
4.5.2 Slope Down (7k)
Slope-Down (or Down Slope or Final Slope or Ramp Down or t
seconds. This is the time taken for the amperage to ramp down from Main Amps to End Amps. This
allows the operator to complete the weld without leaving a 'crater' at the end of the weld pool. See
12.4.1 for more information.
4.5.3 Finish Amps (7l)
Finish Amps (or Finish Current or End Current or I
In 2t Mode: This is the final setting (adjustable 5-9A) that the welding current will ramp down to after
the torch trigger is released at the end of the weld. This is only applied if the Slope Down setting is
greater than 0.
In 4t Mode: This amperage setting (adjustable 5-9A) is maintained while the torch trigger is held down
at the end of the weld. Once the trigger is released welding arc will stop.
4.5.4 Post-Gas Time (7m)
Post Gas (or Post Flow) 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. Adjustable 0 – 10 seconds.
4.5.1 SmartStart AC (7n)
SmartStart AC is a unique setting which can be adjusted to make weld starting easier when welding with
AC current.
When welding aluminium, the material being welded and also the Tungsten electrode will have an oxide
layer on them which acts as an insulator & presents an obstacle to igniting the welding arc.
SmartStart AC delivers a specific amount of positive current at a specific energy level for a specific period
of time. This has the results of delivering very smooth and reliable AC arc ignition, every weld!
The setting is measured in as an 'energy' level (not time). Refer to the below chart for the recommended
setting ranges for different Electrode sizes. The setting may also very depending on the Tungsten
Electrode type used and specific applications.
The machine will 'beep' and flash up the Electrode diameter as the operator adjusts through the settings
ranges to make it easier to set within recommended ranges.
