Effects of pressure and time on dot size |
Note the effect on dot size by applying different air pressure, time settings and tip sizes. |
|
Increasing either the air pressure, time duration or tip size will increase the dot size. |
|
Decreasing either the air pressure, time duration or tip size will decrease the dot size. |
|
Thicker, more viscous liquids, such as pastes or greases, will require either more pressure, longer time or a larger size tip. |
|
Thinner, less viscous liquids, such as cyanoacrylates or thinners, will require less pressure, shorter time or a smaller tip size. |
|
Higher pressure and/or short time cycle increases the dispensing speed and provides a higher output. |
|
Lower pressure and/or longer time cycle improves accuracy in deposit size. |

How to make consistent deposits |
The best angle to hold the barrel is between 45º and 80º degrees. The barrel should be lifted vertically to avoid spoiling the deposit. |
|
When making a dot, bring the tip into contact with the work surface at the angle illustrated. Depress the foot pedal to initiate the shot and keep the barrel in position until the cycle is complete. |
|
Remove the tip from the deposit by moving the barrel straight up. With the air pressure and time set, each successive deposit will be identical. |
Fluid filling (loading) |
Fluid loading is dependent on the type of material you are using. |
|
Low viscosity fluids. |
|
Simply pour low viscosity materials into the barrel, leaving an air space at the top. For best results fill the barrel to 2/3rds full and refill at 1/3rd full. |
