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 influence in
the melt-off rate of the wire that will have an influence on the
weldbead profile.
Influence of the change in electrical stickout length on the weldbead
profile.
The travel speed will have an influence on the weldbead profile 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.
