2.Check whether the acetylene hose body has cracks, bulging, dent deformation, scratches and whether the base splicing welds are cracked and other problems.
3.Check the corrosion of the acetylene hose body, especially check the corrosion of the bottom and side seams of the acetylene bottle carefully.
4.Check whether the acetylene hose and accessories are defective and damaged.
5.Check whether the color of acetylene hose is off and discolored, if the color of the gas cylinder is not correct, check carefully to determine whether it is acetylene hose. If the new bottle should be pumped into vacuum and replenished with acetone. Open the cylinder valve and check whether the inner core and valve stem of the cylinder are intact and not slipping when measuring the residual pressure of gas with the residual pressure table.
