SECTION 4 4.4 Influence of Gas Options Cut Quality OPERATION 4.4.1 Introduction All gases are not suitable for all situations. Certain gases assist in cutting specific materials and thickness. The following explains why certain gases are selected and their influence on the finished part. Other influences such as arc voltage and gas flow/pressure are covered in the process data. ! DANGER Hydrogen explosion hazard. • Do not cut under water with Hydrogen gas! • Hydrogen explosions can cause personal injury or death. • Hydrogen can create explosive gas pockets in the water table. These pockets will explode when ignited by sparks or the plasma arc. • Before cutting, be aware of possible hydrogen sources in the water table – molten metal reaction, slow chemical reaction and some plasma gases. • Explosive gas pockets accumulate underneath the cutting plate and inside the water table. • Clean slag (especially fine particles) from bottom of table frequently. Refill table with clean water. • Do not leave plate on table overnight. • If water table has not been used for several hours, vibrate or jolt it to break up hydrogen pockets before laying plate on the table. • If possible, change water level between cuts to break up hydrogen pockets. • Maintain water pH level near 7 (neutral). • Programmed part spacing should be a minimum of twice the kerf width to ensure material is always under the kerf. • When cutting above water, use fans to circulate air between plate and water surface. 4-9
