Product DetailsLeisterʼs BITUMAT B2 is designed to weld modified bitumen roofing sheets (SBS, APP).

This automatic welder is safer than traditional welding torches because it uses hot air to heat the bitumen, not an open flame, decreasing the risk of fire.

It is also more efficient because it only requires one operator—unlike open-flame torches where two operators are needed—helping to keep your workforce more productive.

The BITUMAT B2 is the only bitumen welder that makes granular-to-granular welding possible. The BITUMAT B2 produces so much heat that the bitumen liquifies, melting the granular surface into the material before the two pieces are firmly pressed together to create a strong weld.

How to Test Weld QualityBITUMAT B2 heat output can be affected by an improper balance of temperature, speed, air volume and pressure, as well as external factors, such as moisture, humidity, ambient temperature and direct sunlight.

For this reason, before every use, always run a test weld on scrap material to make sure you have the proper settings. To perform 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)

Operating Instructions

17

2322 888-785-4485

Operating InstructionsA 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.

It is important to clean the BITUMAT B2 nozzle after every use to avoid bitumen buildup that restricts airflow. Buildup can cause the machine to overheat, damaging the heating element.

To clean the nozzle, use a stainless steel or brass wire brush, and in a motion away from your body scrape the excess bitumen off.

Make sure the nozzle is still hot while you do this because the bitumen will be more difficult to scrape away if it has had time to cool and solidify.

Continue until you can see that all the air holes are clear of blockages. At least once a week, hold up the nozzle to a light source and check that light is showing through all air holes.

Resources:How ToClean a Nozzle

Safety Recommendations:

• Hold the hot-air blowerʼs green handle with your free hand to secure it in place while scraping.

• Wear protective gloves and safety glasses.

• Make sure the blower is turned off so that loose bitumen pieces are not blown into the air.

Built-up bitumen can cause the drive roller to lay unevenly against the material surface, leading to a poor weld. For this reason, itʼs important to clean your drive roller after each use. To do so:

1. Unscrew the brass fastening screw and pull it away from the drive roller.

2. Pull the drive roller off the machine. 3. Spray silicone onto the drive roller and a clean rag.4. Wipe away the bitumen using the rag. 5. Once clean, coat the drive roller with a layer of silicone to help keep

it clean.6. Reinstall the drive roller and secure it in place with the fastening

screw.

Resources:How ToTo reinstall the lifting device, follow the steps on the previous page in reverse order.

When going through the reinstallation process, keep the following tips 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.

• 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 be the thickness of a dime.

Insufficient Space

There 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 welding issue, 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.

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).

Resources:TroubleshootingPoor Weld Quality

Note: The amount of air blowing through the heating element will have an inverse affect on heat output, limiting how hot the BITUMAT B2 can get.

41

4038 888-785-4485

3. 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.)

Resources:Troubleshooting

Generator

Contact your distributor or the manufacturer to troubleshoot the issue and determine the appropriate fix.

Wall Outlets

•Invest in a generator to ensure you have a consistent power source from job site to job site.

•Purchase a buck-boost transformer, which can help to maintain consistent power output.

•Contact a certified electrician to examine the electrical system. He or she may be able to safely boost power output.

42

404038 888-785-4485

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 need to send it to an authorized Leister service center for support.

WARNINGS

• It is dangerous to open the BITUMAT B2 casing while the machine is plugged in because electrified components and connections are exposed. Unplug the machine before opening it.

• Incorrect use of the hot-air welder can cause a fire, and is an explosion hazard around combustable materials and gasses.

• Do not touch a hot welding nozzle, as they can cause burns. Allow it to cool first.

• Do not point the hot airflow in the direction of people or animals.

• Connect the tool to a power source with a grounding conductor. Any faults of the grounded conductor inside or outside the tools are dangerous.

• Only use extension cords that are grounded.

Warnings and CautionsCAUTIONS• Rated voltage stated on the device must correspond to the power voltage—N 61000-3-11; Zmax = 0.105 Ω + j 0.066 Ω. If necessary, consult an electrician.

• In case of a power failure, unplug the machine and set the main power switch to 0.

• For personal protection, we strongly recommend the BITUMAT B2 be connected to an RCCB (Residual Current Circuit Breaker) before operation.

• The tool must be operated under supervision. Hot air can ignite flammable material that is not in view.

• The machine should only be used by qualified specialists or under their supervision. Children are not authorized to use this device.

• Protect the device from exposure to damp or wet areas.

• When lifting the BITUMAT B2 by hand, use the carrying handle and top of the guide bar.
