Replacing the nozzle
There are 2 reasons for replacing the nozzle:
1. Changing nozzle type to weld another welding processes (Round nozzle / Rectangular nozzle)
2. Replacing a damaged or used nozzle by a new one.
After replacing the nozzle, it is important to adjust the perpendicularity to ensure a good preheating.
Procedure
3. Untighten the 4 nuts that hold the nozzle
4. Replace the nozzle
5. Put back the 4 nuts
– Do not tighten it so it stays loose.
6. Align the perpendicularity with the ground. To facilitate the operation, the HFP should be put on a flat and
horizontal surface.
7. Tighten slightly the 4 nuts
8. Align the vertical and horizontal perpendicularity. Those perpendicularities are obtained by adjusting the
compression level of the seal.
o
Tightening the upper nuts / loosing the lower nuts makes the nozzle to rise. (And opposite)
o
Tightening right nuts / losing left nuts make the nozzle to turn right. (And opposite)
