LED Display

 

 
3 digit LED meter is used to display the main amperage when welding, it will also show 
current parameter value when using selector buttons to scroll through additional settings I.E 
Pre-flow gas, start amps, up-slope ,peak amps, slope down, end amps, post flow gas etc. 
 

14.  TIG starting control 

 

HF - Mode LED is Green: The arc will automatically start when trigger pressed without 
touching tungsten electrode to workpiece 
 
Lift – Mode LED is Red: The arc will start by touching the tungsten electrode to work piece, 
when the tungsten is then lifted of the work piece the arc will start. Used for when welding 
on vehicles with sensitive electronics. 

 

15.  Pre-flow gas

 

 
This sets the amount of time gas flow will happen before arc is started, for most jobs 0.1 -
0.5 seconds if fine, when welding stainless steel where a longer gas purge time may be 
required adjust accordingly. Range is 0 to 10 seconds. 

 

16.  Start Amps 

 

When in Tig mode with 2T/4T operation set, this will adjust the start amperage 
 
This allows you to set the initial start current from 5A DC. In 4T mode when trigger is 
pressed and held you will remain at start amps, when you let go machine will then go to 
main set amps.  
 
Do not set the start amperage too low for tungsten size otherwise you may experience 
sluggish / non arc starting. I.E A 3.2mm tungsten is for high range 160+ amps welding, so 
you would not need to set start amps at 5. The thicker the tungsten used the higher the 
start amperage has to be. We recommend to achieve faster arc starting:- 
 
1.0mm Tungsten - 5 Amps minimum 
1.6mm Tungsten - 15 Amps minimum 
2.4mm Tungsten - 30 Amps minimum 
3.2mm Tungsten - 50 Amps minimum 

 
 

17.  End Amps 

 

When in Tig mode with 4T operation set, this will adjust the end (final) amperage 

 

18.  Memory store

 

 
You can program up to 9 jobs into memory - very helpful when doing process welding. 
Press button to select required memory and options will be set as pre-programmed into job. 
 
To program, select job number required, enter parameters I.E amps / upslope / downslope / 
gas post flow, then press and hold program button for 3 seconds, this will save current 
settings. 

 

19.  Select function 

 

Press left or right to scroll through available parameters, Once required parameter LED is
