Whether you're a welder or a plumber, a blowtorch could be the very thing you need. Of course, you must comply with safety regulations and be familiar with the mechanics before you begin. But that said, you will find the blowtorch a wonder tool. Take this quiz to see what you know about the humble blowtorch.
What are the sparks that you see coming out from a blowtorch?
tiny pieces of molten metal
reflective glints of sunshine
With mishandling of the blowtorch or improper pressure, what could happen?
A fire could break out.
The blowtorch could work intermittently.
The blowtorch could generate more heat.
What revolution in the welding process did the 19th-century invention of the blowtorch cause?
Welding could now be more precise by focusing high heat on a small area.
Welding could now be accomplished by the untrained worker.
Welding could now be performed on non-metals too.
Why is welding a high-paying job these days?
because welding as a career choice is unpopular, so good welders are a rarity
because welding takes many years to learn
because welding involves very expensive materials
Which of these are essential components of a blowtorch?
face mask and laser light
gas cylinder and hoses
metal straps and drainage well
What is the function of the regulators?
to regulate the heat of the blowtorch tip
to regulate the amount of gas released
to control gas pressure and flow
Why shouldn't you light the blowtorch with a match?
because you'd need someone else to hold the blowtorch for you while you're holding the match
because you might inadvertently forget to extinguish the match flame
because of the extreme heat of the flames
In terms of gas pressure, what is the rule regarding the hose and the torch head?
The torch head pressure should be more than the hose pressure.
The pressure should always be even between the two.
The hose pressure should be more than the torch head pressure.
What gases are commonly used in home blowtorches?
hydrogen or helium
butane or propane
carbon dioxide or oxygen
Which is the more volatile of the gases used in professional blowtorches: acetylene or MAPP?
both are equally volatile
