 - DC TIG-Pulse- High Speed DC TIG-Pulse Controls 
 • PPS Pulses per second (Hz):DC = 0.1 – 5,000 PPS
 • % ON – % Peak Time:5 - 95% (Controls the amount of time during each pulse cycle at the PEAK amperage.)
 • Background Amps:5 – 99% (Sets the low-pulse amperage value as a % of the Peak Amps.)- CONVENTIONAL PULSED TIG - HIGH SPEED PULSED TIG  - Typically from 1 to 10 PPS. Provides a heating and 
 cooling effecton the weld puddle and can reduce
 distortion by lowering the average amperage. This
 heating and cooling effect also produces adistinct
 ripple pattern in the weld bead. The relationship
 between pulse frequency and travel speed determines
 the distance between the ripples. Slow pulsing can
 also be coordinated with filler metal addition and
 can increase overall control of the weld puddle. - In excess of 40 PPS, Pulsed TIG becomes more 
 audible than visible—causing increased puddle
 agitation for a better as-welded microstructure.- Pulsing the weld current at high speeds — between 
 a high Peak and a low Background amperage —
 can also constrict and focus the arc.This results in
 maximum arc stability, increased penetration and
 increased travel speeds(Common Range:100–500- PPS).The Arc-Sharpening effects of high speed 
 pulsing are expanded to new dimensions. The ability
 to pulse at 5,000 PPS further enhances arc stability
 and concentration potential — which is are required.- Hot Start- Hot start function reliably ignites the electrode and melts 
 perfectly to ensure the best quality even at the start of
 the seam. This solution makes lack of fusion and cold weldsa thing of the past and significantly reduces weld reinforcement.
 Adjust the hot start current here and the time here. - Arcforce correction (welding characteristics) - During the welding process, arcforce prevents the electrode sticking in the weld pool with increases in current. 
 This makes it easier to weld large-drop melting electrode types at low current strengths with a short arc in particular.- 2T/4T- Non-latched mode - 1st cycle: 
 • Press and hold torch trigger 1.
 • The gas pre-flow time elapses.
 • HF ignition pulses jump from the electrode to the workpiece,the arc ignites.
 • The welding current flows and immediately assumes the value set for the ignition current Istart.
 • HF is switched off.
 • The welding current increases in the set up-slope time to the main current AMP.
 Switching from main current AMP to secondary current AMP%:
 Press torch trigger 2 or Tap torch trigger 1
 2nd cycle:
 • Release torch trigger 1.
 • The main current decreases in the set down-slope time to the end-crater current Iend (minimum current).
 If torch trigger 1 is pressed during the down-slope time,
 the welding current increases again to the set main current AMP.
 • The main current reaches the end-crater current Iend, the arc extinguishes.
 • The set gas post-flow time elapses.- Latched mode - Step 1 
 • Press torch trigger 1, the gas pre-flow time elapses.
 • HF ignition pulses jump from the electrode to the workpiece, the arc ignites.
 • Welding current flows and immediately assumes the ignition current value set
 (search arc at minimum setting). HF is switched off.
 Step 2
 • Release torch trigger 1.
 • The welding current increases with the set up-slope time to the main current AMP.
 Switching from main current AMP to secondary current AMP%:
 Press torch trigger 2 or Tap torch trigger 1
 Step 3
 • Press torch trigger 1.
 • The main current decreases in the set down-slope time to the end-crater current Iend (minimum current).
 Step 4
 • Release torch trigger 1, the arc extinguishes.
 • The set gas post-flow time begins.
 Immediate termination of the welding process in the downslope by releasing torch trigger 1.
