•
- Increase of heat-affected zone.
- PEAK TIME
○ Time for which the current pulse is at the maximum value.
○ The SET UP, PULSED TYPE=FAST settings, the adjustment is a % of the PULSED CYCLE
(CYCLE TIME=1/PULSED FREQUENCY).
○ In the settings for SET UP, PULSED TYPE = SLOW, the adjustment is expressed in seconds.
-
Consequences of a higher value:
•
- Greater width of the beading and greater welding penetration.
•
- Facility to make deeper cuts.
-
Consequences of a lower value:
•
- Reduction of the bead and of heat-affected zone.
•
- Difficult to create a weld pool.
- PULSED CURRENT FREQUENCY
○ The greater the frequency, the tighter the bead welding and greater the welding time. Increasing
the frequency, restricts the heat affected zone. A high frequency (kHz) pulsed arc is suitable for
flat beading (head to head or over head)
-
Consequences of a higher value:
•
- Slower melt speed.
•
- Reduction of heat-affected zone.
- BASE TIME
○ Time during which current output is at the base value. Available with settings for SET UP, PULSED
TYPE = SLOW, the adjustment is expressed in seconds.
-
Consequences of a higher value:
•
- The filler material is spread more evenly.
•
- Increase of heat-affected zone.
- DOWN SLOPE
○ Time during which the current changes from the welding value to the end value by means of a
slope. Prevents the formation of craters in the process of turning off the arc. The parameter is not
used during the welding process when the following setting is present: MULTI TACK = ON
- FINAL CURRENT
○ During electrode welding the parameter makes it possible to obtain a uniform deposit of filler ma
-
terial from the start to the end of the welding process, closing the deposition crater with a current
such as to deposit a final droplet of filler material.
○ The value of this parameter can be set as a percentage of the welding current or as an absolute
value expressed in Amperes.
○ The parameter is displayed but it is not used during the welding process when the following set
-
ting is present: MULTI TACK = ON
○ By keeping the torch trigger pressed during the 3rd time, the crater filler current is maintained
thereby ensuring optimal crater filling, until the post gas time is started by releasing the torch trig
-
ger (4th time).
- POST GAS TIME
○ Time of post gas delivery when the welding arc is extinguished.
-
Consequences of a higher value:
•
More effective pickling (improved appearance of workpiece at the end of the welding pass).
•
- Higher gas consumption.
-
Consequences of a lower value:
