A
LL SAFETY PRACTICES MUST BE OBSERVED
.
Daily:
•
Clean exterior of machine to rid of solder deposits, flux, and dirt.
−
Use household cleaners like “409”.
−
For non-water soluble dirt (flux) use mineral spirits.
Note:
W
HEN CLEANING BE CAUTIOUS OF PAINTED SURFACES
,
LABELS
,
OR PLASTIC
(
SWITCHES
)-
PROLONGED CONTACT OF SOLVENTS WILL ATTACK SURFACE
.
•
Remove dross from flow well and pot cover. The inherent nature of solder generates dross as a
by-product which must be removed periodically depending on the module usage and in-house
criteria. Dross removal can be accomplished only when solder is molten.
•
Remove dross from top of solder bath. Remove dross from around impeller shaft. A fine black
powder will collect at the surface where the rotating impeller shaft enters the molten solder.
Remove with spatula tool. Dispose of dross in a metal container. The dross is at a very high
temperature and should not contact anything that can melt or catch fire.
•
Report any problem to supervisor. Fix any problems before further damage to the machine or
customer assemblies occur.
Weekly:
•
Apply film of oil on all surfaces which solder may fall (except pot cover). Apply 3 in 1
household oil to metal surfaces (around solder pot area) to inhibit solder and flux from permanently
sticking to them. Remove side shields to get access.
Note:
S
OLDER POT MUST NOT BE HEATED
.
•
Apply oil to board carrier. To protect from rusting apply oil to rails and arms of carrier. If rust
appears, it can be removed with WD40 and fine emery cloth or scotch brite pads.
