Selecting The Right Tip; Tip Hole Size - Graco Magnum Pro Plus A30 Operation Instructions Manual

Selecting the Right Tip

Tip Hole Size

• Spray should be atomized (evenly distributed, no
gaps or edges). Start at a low pressure setting,
increase pressure a little at a time until paint atom-
izes.
• Fluid flow rate is controlled by tip hole size.
• The best tip hole size for fluid you are spraying is
determined by type of coating and type of surface
you are spraying.
• Use large tip hole size when spraying thicker coat-
ings.

• Use small tip hole size when spraying thinner coat-
ings.
• Tips wear and enlarge when you spray. Starting with
a tip hole size smaller than the maximum will allow
you to spray within rated flow capacity. To prevent
excessive wear, spray at lowest pressure that atom-
izes paint.
NOTE: If maximum pressure of sprayer is not enough
for good spray pattern, tip is too large or worn. See
Reversible Tip Selection Table, page 14.
