8.2 MMA WELDING PARAMETERS
• WELDING CURRENT
○ This parameter regulates the primary welding current value.
• HOT-START
○ This parameter aids electrode melting at the time of arc striking. It is set as a percentage referred
to the value of the following parameter: WELDING CURRENT. The value is limited to 250A max.
- Consequences of a higher value:
• Ease of activation; Greater starting spatter; increase in the activation area.
• Consequences of a lower value:
• Difficulty of activation; Less starting splatter; Reduction in the activation area.
• ARC FORCE
○ This parameter helps to avoid electrode sticking during welding. It is set as a percentage referred
to the value of the following parameter: WELDING CURRENT
- Consequences of a higher value:
• Fluency factors in welding; Arc welding stability;Increased melting of the electrode within the
workpiece; More weld spatter.
- Consequences of a lower value:
• The arc is extinguished more easily, less welding spatter.
8.3 TIG WELDING PARAMETERS
• 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:
• Lower gas consumption.
• Oxidation of electrode tip (more difficult arc strike).
