Pneumatic sealless steel strapping tool is one of the pneumatic steel strapping tool, this machine get motive power with air supply instead of mauanl strapping. sealless steel strapping tool firstly tension the steel strapping tool  and then press the steel strapping together hardly.

   So the steel strap tension force is important for the strapping process, if the tension force not enough, it would make the strapping effect and performance really bad.
How to avoid sealless steel strapping tension force not enough:

   First, choose suitable width and thickness steel strapping for strapping machine and cargo.
   Second, confirm the strapping tool with good condition, so we can make the tension force higher
   Third, do not forget to check the air pressure, the air pressure need be in 4.5~6Mpa to ensure the good strapping effect and high performance.
