  4. 4. Product DetailsLeisterʼs BITUMAT B2 is designed to weld modified bitumenroofing sheets (SBS, APP).This automatic welder is safer than traditional weldingtorches because it uses hot air to heat the bitumen, not anopen flame, decreasing the risk of fire.It is also more efficient because it only requires oneoperator—unlike open-flame torches where two operatorsare needed—helping to keep your workforce moreproductive.The BITUMAT B2 is the only bitumen welder that makes granular-to-granular weldingpossible. The BITUMAT B2 produces so much heat that the bitumen liquifies, melting thegranular surface into the material before the two pieces are firmly pressed together to createa strong weld. 4 888-785-4485

  16. 16. OperatingInstructionsNOTE: The BITUMAT B2 will take approximately 3-4minutes to reach the proper welding temperature.8. After the welder has warmed up, run a test weld (see pg. 17 for details) on scrap material to make sure the temperature, speed and air-volume settings are properly configured for the job.9. If the test weld does not meet your standards, make any necessary adjustments to the machineʼs settings before moving on. 16 888-785-4485
  17. 17. OperatingInstructionsHow to Test Weld QualityBITUMAT B2 heat output can be affected by an improperbalance of temperature, speed, air volume and pressure, as wellas external factors, such as moisture, humidity, ambienttemperature and direct sunlight.For this reason, before every use, always run a test weld onscrap material to make sure you have the proper settings. Toperform a test weld:1. Cut two, 10-foot strips of bitumen sheeting.2. With the configured and warmed-up BITUMAT B2, weld the two strips together. (conʼt on next page) 17 22 888-785-4485
  18. 18. OperatingInstructionsA good weld should produce a bead of bitumen along the edge of the seam.3. Using a hook-blade, cut three-to-five 2-inch strips perpendicular to the seam. Strips should be cut from the beginning, middle and end of the test weld to ensure quality throughout.4. As soon as the bitumen surface over the seam weld is the same temperature as the rest of the material surface, tear the strips apart.A quality weld should reveal the scrim, or netting, of the bitumen material.

Resources:How ToTo reinstall the lifting device, follow the steps on the previous pagein reverse order.When going through the reinstallation process, keep the followingtips in mind: • Put the BITUMAT B2 on top of a secure, flat surface, and let the front end overhang the edge slightly. This offers greater access to hard-to-reach areas. Insufficient Space • As you tighten the fastening screws of the scraper, pull the scraper toward you. If the scraper is too far back when it is secured, it will rub against the drive roller, causing undue stress on the motor.NOTE: The space between the drive roller and scraper should bethe thickness of a dime. 38 40 888-785-4485
  41. 41. Resources:TroubleshootingPoor Weld QualityThere are a number of variables that can impact a BITUMAT B2ʼs welding performance.Below are three things you can check while on a roof. If none of these resolve the weldingissue, contact IHSʼ authorized service center.To resolve poor welding quality:1. Check that the temperature, speed and air-volume settings are properly configured. If any of these are off for the material or the environment, your seam quality will suffer.Note: The amount of air blowing through the heating element will have an inverse affect onheat output, limiting how hot the BITUMAT B2 can get.2. Make sure the welding nozzle is free of melted bitumen and debris, which can restrict airflow. If you discover any blockages, scrape them away with a stainless steel or brass wire brush (see pg. 37 for details). 41 38 40 888-785-4485
  42. 42. Resources:Troubleshooting3. Make sure the machine is receiving the proper power supply (see pg. 12 for details) by checking (in order) the power source, extension cord, and then machine power cord. • First, check that the power source is producing enough power. Use an AC voltage tester with prong probes, and make sure to wear insulated gloves. If the power doesnʼt meet the machine requirements, below are some tips to resolve the issue. (Click here for a complete blog post on the topic.)Generator Wall OutletsContact your distributor •Invest in a generator to ensure you have a consistent poweror the manufacturer to source from job site to job site.troubleshoot the issue •Purchase a buck-boost transformer, which can help toand determine the maintain consistent power output.appropriate fix. •Contact a certified electrician to examine the electrical system. He or she may be able to safely boost power output. 42 38 40 888-785-4485
  43. 43. Resources:Troubleshooting • If the power source checks out, next test the extension cord. Use the voltage tester to test the cord outlet that the machine plugs into. If there is a problem detected, youʼll need to purchase a new cord. • Lastly, check that the BITUMAT B2ʼs power cord is not frayed, cut or sliced. If it is, it will need to be replaced by an authorized Leister technician.After youʼve ruled out all these variables, if your machine is still welding poorly youʼll needto send it to an authorized Leister service center for support. 43 38 40 888-785-4485
