Welding Position
Place the tip at 3-4 mm (.12 - .16in) from the weld piece, press the torch trigger, the arc will automatically ignite; as
soon as the bath forms, move slowly and with constant speed so as to produce a bath that is uniform in penetration
and width.
If filling material is used, keep the rod at a slope and about 20 mm (.79in) from the piece; when the weld pool
becomes fluid, move the torch back and add material, touching the rod to the pool. (Filling material is always
necessary for aluminium.)
Pull the rod away and position the torch back near the weld bead.
Repeat this operation quickly and constantly so that the weld remains homogenous.
