This photo shows the test setup we used. The TM2100CLO torch is heating one side of the copper plate and the CEM InfraRed Thermometer is measuring the temperature directly on the opposite side. The CEM is 6" away from the plate and has a 0.5" measurement circle on the plate. The CEM has a laser pointer so you know where you are measuring the temperature. We always search for the maximum temperature during these tests to be objective in the measurements. This is a very fair test because we are measuring the work piece temperature, and the test results will be very repeatable. We measured the temperature every 30 seconds. Every time we run a test, we cooled the plate in a bucket of water and let the plate stabilize at room temperature.

When compared to CROSSTECH PROFESSIONAL TORCHES, the #1 brand torch is NOT superior to ours. The TM2100CLO uses 18.8% less fuel than the #1 brand, but also the TM2100CLO heats the work piece faster and has a higher work piece temperature. During our testing we could see the #1 brand flame intensity significantly reduced as the torch tip was being operated less than ideal tip pressure. This fact confirms that they are take much more fuel out of the cylinder then we do. The TM2100CLO did not have this problem and operated at normal tip pressure of 48 PSI. The TM2100CLO is rated to operate with MAPP® gas at room temperature for 20 minutes. The #1 brand torch had a tip pressure of 59 PSI.
We believe the reason for the CROSSTECH PROFESSIONAL TORCHES have excellent performance is because of our higher flame speeds and laminar flow though our flame stabilizers which we have been using since 1978. We have never had to improve the stabilizers in our designs nor the venturi used in our torch tips.
Our test work pieces are probably on the extreme size because the temperatures attained were below those necessary for silver brazing. They however provide a fair comparison between the products tested.
