Excessive drag lines during oxygen-fuel cutting typically indicate that the cutting torch is moving too slowly or that the oxygen pressure is too low. This can lead to poor cutting quality, with increased slag and an uneven cut surface. It may also suggest improper technique or that the torch tip is worn or damaged. Adjusting the cutting speed and ensuring proper gas pressures can help mitigate this issue.

What is the meaning of the coloured lines on a laser cutter?
In laser cutting, colored lines typically indicate different cutting or engraving settings. Each color corresponds to a specific operation, such as cutting, scoring, or engraving, and may also represent variations in speed and power settings for the laser. For example, a red line might signify a cut, while a blue line might indicate engraving. This color-coding helps operators efficiently manage and execute their design files during the cutting process.
What are the different types of sectional lines?
Sectional lines are used in technical drawings to indicate different features or materials in a section view. The main types include solid lines, which represent visible edges; dashed lines, showing hidden details; and center lines, indicating the center of circles or symmetrical parts. Additionally, cutting-plane lines are used to indicate where a section is taken, often marked with arrows. Each type serves to enhance clarity and understanding of the drawing.
What does widely spaced lines indicate?
I am very sure that widely spaced lines indicate flatness.
Thin unbroken lines used to indicate dimensions are?

Contour lines that are far apart indicate?
Contour lines that are far apart indicate gradual slopes, while contour lines that are close together indicate steep slopes.
How do you draw two water moleculer with dashed lines to indicate where hydrogen bonds form between the molecules?
To draw two water molecules with dashed lines to indicate hydrogen bonds forming between them, represent each water molecule as an oxygen atom (O) with two hydrogen atoms (H) bonded to it. Then, draw dashed lines connecting the oxygen atom of one water molecule to the hydrogen atoms of the other water molecule. These dashed lines represent hydrogen bonds forming between the two water molecules.
Why there are markings of two parallel white lines and yellow lines on roads?
(in the US) They indicate a no passing zone. The white lines indicate multiple lanes of travel in the same direction, while the yellow lines indicate opposing lanes of travel.
What do the numbers on index contour lines indicate?
The numbers of contour lines indicate altitude or elevation along that line.
What do two white parallel lines on the road indicate?
Two white parallel lines indicate that no passing is allowed.
On a topographic map contour lines that are closer together indicate?
On a topographic map, contour lines that are closer together indicate a steeper slope.
Contour lines on a map indicate?
Contour lines on a map indicate elevation. They connect points of equal elevation, showing the shape and steepness of the terrain. Closer contour lines indicate steep slopes, while spaced-out lines represent flatter areas.
Is Laser cutting of steel a thermal cutting process?
CO2 laser cutting carbon steel with oxygen is an exothermic (thermal) process. The oxygen used with the laser cutting burns the steel, thus assisting the cutting process. This process causes striations, or lines, to form at the cutting edge and provides lower cut quality but faster cutting. In contrast, when cutting stainless steel with nitrogen, only the heat from a CO2 laser performs the melting (operating in the far infrared region at 10600 nanometers). The nitrogen assist gas pushes the melted material down and out of the way, leaving the cut that is typically a polished edge.
