Note:
When using foot pedal ensure this is set to minimum unless you want to have a
HOT burst at end of weld.
14.
Post Flow Gas
Adjustable from 0 - 50 seconds. When you stop welding the gas will continue to flow for this
set amount of time, this allows the tungsten to cool without getting contaminated and also
protect the weld bead until it has cooled slightly.
For up to 100 amps use about 8 seconds, for 100 - 150 use 12 seconds and 150-210 use
15 seconds.

Process selector
Options are:-
HF Tig - For automatic arc starting (normal setting for AC & DC Tig Welding)
Lift Tig - If welding near sensitive electronic devices (car ECU etc) DC Only
Stick - NON VRD - Normal 70v OCV is present before welding happens
Stick - VRD (Voltage reduction device).
The OCV is reduced to below 20V (+/- 3v) for added safety. Once the electrode touches
workpiece the arc is established and weld carries on as normal. However when using VRD
sometimes it can be harder to strike the arc and you may need to scratch the electrode on
work a bit more, even more so with rusty / dirty metals.
When welding with VRD you may notice a slight delay in the initial striking, this is normal.

Parameter selector
Press this button to scroll left to right through the machine parameters
17.
Parameter adjuster
Turn this knob to adjust parameter values, if you hold the knob in and turn it increase
adjustment speed.
18.
MMA Arc Force control
This controls the arc response to when electrode is held close/away from workpiece. Arc
force automatically adjusts by changing the volts / amps to maintain a stable arc.
This is represented as a % of available arc force amperage
19.
MMA Hot Start time
Adjusts the time from 0 - 2 seconds that the hot start will happen at beginning of weld. This
helps to reduce electrode sticking to work.
20.
MMA Hot Amps %
For controlling the amount of extra amps when the arc is first started and prevents the
electrode sticking to work. Adjustable from 0 - 100% of hot start amps available.
