The Difference Between Bump and Sequential Firing


The Difference Between Bump and Sequential Firing

Electric nail guns are powerful tools with an easy-to-operate trigger mechanism to boost productivity. It’s important to understand how different trigger mechanisms work to prevent errors when purchasing them or using them on a job site.

Nail gun triggers vary based on how the operator uses the trigger and the safety tip on the nose. The trigger mechanism can vary based on the order in which the user activates these controls and whether they can hold the trigger to discharge multiple nails. Some nail gun models contain a selective trigger switch to allow the user to choose between trigger systems. The following information provides insight into the difference between bump and sequential firing and how these mechanisms affect the safety risk of the user.

Full Sequential Firing

Full sequential firing earned the name “single-shot firing” because of how the user actuates the nail gun controls in a series. The user must press the safety tip, then pull the trigger to release a single nail.

Full sequential firing suits small-scale projects where precision is more important than speed. It’s best to use this form of firing for applications like framing, carpentry, or fastening surfaces with defined holes.

Single Sequential Firing

Single sequential firing has a similar mechanism to full sequential firing because it also requires the user to activate the controls in a series.

Single sequential firing doesn’t require the user to lift the tool. Instead, they can just drag the safety nose across the surface. The single sequential firing trigger operates at a higher speed than the full sequential trigger.

Contact or Bump Firing

Contact firing earned the name “bump firing” because the user can “bump” the safety tip against a surface to continuously fire nails.

Bump firing suits large-scale projects that don’t require specific fastener placement. It’s best to use bump firing on horizontal and flat surfaces, such as flooring, decking, roofing, and pallet making.

The sequence of the controls has no effect on the trigger mechanism, which means you can rapidly fire nails. In bump firing, you must both pull the trigger and press the safety tip to release nails.
