I've got a similar one.. Not a twin brother but in the family.
If you are going by factory tip charts to determine your travel speed for a given thickness, it's a good idea to calibrate your track burner about every six months.... I've found that the inches per minute can change pretty significantly with the seasons, even indoors. Or maybe it's ancient rheostats simply wearning away...
Alot of people think (especially with Bug-o's) that the numbers on the dial represent inches per minute... I've never found this to be the case if you actually measure how fast the torch travels in a minute :)
The cut you made looks great... You prolly just use the *force* to set the thing eh?
Hello weldwade, I've got a personal track burner similar to yours also. I believe mine is actually a "Heath Kit", Victor also built, or had a similar one built for their product line. As far as settings and such, I generally select tips, pressures, and the rest from the manufacturers suggestions, Travel speed is much more the result of analyzing the flame, amount and look of dross being emitted from the underside of the cut, and the sound. They are a very adequate and reliable machine. Enjoy yours and may the force be with you. Best regards, Allan
