Gas Consumption

In China,one bottle of Oxygen is 8 $/bottle, Nitrogen is 16$ /bottle.

Standard oxygen or nitrogen gas bottle is 40L/bottle.

1.For carbon steel, we mainly use Oxygen to cut.

For carbon steel cutting, the thicker, the less Oxygen pressure need. 

2.For stainless steel, mainly use Nitrogen to cut.

The thicker of the stainless steel, the higher Nitrogen pressure we need.

3.As for the gas, clients mostly use oxygen and nitrogen,also some choose compressor air.

When using the compressor air, we should make sure the compressor air up 13bar,

something need to keep in mind:

Firstly,make sure your gas cylinders have enough air.

Usually 1.8m height air tanks is enough.

Secondly,the compressor air must be dry and clean,

without any water and dust.

Thirdly,also need dryer and filter

4.Other Precautions of using laser cutting machine

Fiber laser cutting machine laser source is fiber laser generator,

it will give out waste gas when cutting, some of gas are harmful.

So when cutting these special materials, need to deal with the waste gas and then give out.

The fiber laser source is category 4,laser beam is harmful to human boy, especially to eyes.

Workers need to protect themselves, also should prevent fire.
