BOC Smootharc 180 Multiprocess operating manual
Torch position for llet welds
When welding llet welds the torch should be positioned at an angle of
45° from the bottom plate with the wire pointing into the llet corner.
Welding is still performed in the push technique.
Electrical stickout
The electrical stickout is the distance between the end of the contact
tip and the end of the wire. An increase in the electrical stickout results
in an increase in the electrical resistance. The resultant increase in
temperature has a positive inuence in the melt-o󹟽 rate of the wire that
will have an inuence on the weldbead prole.
Inuence of the change in electrical stickout length on the weldbead
prole.
The travel speed will have an inuence on the weldbead prole and the
reinforcement height.
If the travel speed is too slow a wide weldbead with excessive rollover
will result. Contrary if the travel speed is too high a narrow weldbead
with excessive reinforcement will result.
