1.0 Equipment General Description and
Assembly
The equipment described in this manual was designed and built to produce permanent
characters directly onto parts. The general equipment layout can be seen on the drawings
for this equipment. (See Drawing Section of this manual) As with any piece of equipment,
no one can merely read the instruction manual and then hope to operate that equipment
safely and efficiently. Contact your local ITW Ramset dealer for operator training and
certification.
1.1 Ramset D45A General Description
The model D45A is a semi-automatic, low velocity, powder actuated tool that uses .25
caliber, 10-shot disc loads. The disk loads, which are available in five power levels,
automatically feeds into position when the tool is operated. The D45A is ideal for
permanently marking a variety of materials. When the tool is in position to mark, pulling the
trigger releases a firing pin, which strikes the powder load. This causes the powder in the
load to ignite and burn, providing a powerful release of expanding gases which drives the
piston down the barrel of the tool, striking the anvil of the Portamark. The resulting impact
drives the marking characters into the work surface. Reference the manual that is provided
with the Ramset D45A for additional information and instructions.
1.2 Portamark-Marking Attachment General
Description
The Portamark marking attachment is designed to work specifically with the Ramset model
D45A powder actuated tool. The Portamark can be supplied in either urethane for cold
marking, or steel for hot marking applications. The Portamark is attached to the D45A tool
with a threaded shank and locking ring. When fired, the piston strikes the anvil, positioned
behind the type, and the mark is achieved. The Portamark will accommodate five pieces of
1/2” type, six pieces of 3/8” type, eight pieces of 5/16” type, or ten pieces of 1/4” type.
