Welding of modified bitumen sheeting (SBS, APP) with Leister’s flameless BITUMAT B2 is faster and safer than with an open flame. Only one user is needed to properly operate the BITUMAT B2 (for open-flame machines two users are needed — one for heating and one for pressing on), enabling your team to complete the job more efficiently. Welding results will also be stronger and more consistent with hot air.

  • Flame-free welding of modified bitumen
  • Consistent welding results
  • Easy control of hot air volume
  • High working speed of up to 39.4 ft/min
