GMAW SETUP
ALUMMIG
230
This setting adjusts the voltage which relates to the arc length and overall heat input of
the weld. Higher voltage settings eg +6 arc length will produce a longer hotter arc
making the wire burn back closer to the torch tip. Lower voltage settings will produce a
colder shorter arc eg -5 arc length with the arc burning closer to the weld pool.
Joint type and welding technique will determine what voltage and arc length is used for
the best result. When decreasing voltage/arc length you can compensate by increasing
the wire feed speed/amperage and vice versa. Other factors that will change the heat
inputs needed is the dual pulse, pulse frequency and inducatnce settings. It is always
recommened to test the machine settings on scrap material before commencing
welding on the job at hand.
