Oxyfuel Basics
This process is most suitable for cutting ferrous metals like carbon steel.
What is oxyfuel cutting?
A properly tinted lens used for oxyfuel cutting falls within this shade range.
What is shade 3 to 6?
SMAW is commonly known by this name.
What is stick welding?
This voltage is present when the machine is on but no arc is active.
What is open-circuit voltage?
This output rating is paired with duty cycle to determine welding machine capacity.
What is rated amperage?
The chemical reaction during oxyfuel cutting causes the metal to do this.
What is oxidize?
Oxyfuel fittings with left-hand threads and a V-notch are used for this.
What are fuel gas fittings?
This device converts AC to DC in a welding machine.
What is a transformer-rectifier?
To prevent welding machine tip-overs, always connect the lifting eye to this.
What is a shackle?
These connectors provide a quick disconnect for welding leads.
What are DINSE®-style connectors?
Combining pure oxygen with a burning material causes this.
What is rapid and violent combustion?
These safety devices prevent reverse gas flow and flashbacks.
What are check valves and flashback arrestors?
SMAW machines are designed to maintain this type of current.
What is nearly constant current?
Fall protection equipment should be inspected this often.
What is before each use?
This should be done to a work clamp before using it.
What is ensure it matches the rated machine capacity?
This type of flame has an excess of fuel gas.
What is a carburizing flame?
This test, performed with a bubble-forming solution, checks for gas leaks.
What is a leak test?
A current with no frequency and a straight waveform.
What is direct current (DC)?
These safety tools are used to remove slag and coatings from welds.
What are wire brushes and chipping hammers?
To reduce voltage drop, longer welding leads must be matched with this.
What is a larger cable size?
The process of burning a small hole to start a cut is called this.
What is piercing?
When shutting down oxyfuel equipment, the regulator adjusting screws should be positioned like this.
What is both screws loose?
The number of cycles completed per second in AC current.
What is frequency?
This toxic gas can accumulate from engine-driven machines in closed areas.
What is carbon monoxide (CO)?
SMAW creates a weld by completing an electrical path through this.
What is an arc?
