What are the conditions of good starting performance of welding machine?

⑴ Sufficient starting speed. The starting speed is high, the gas leakage in the cylinder is small, the heat transfer time of compressed air to the cylinder wall is short, and the heat loss is small, so that the gas temperature and pressure at the end of compression can be increased. Generally, the speed is required to be above 1_0_0_r_/_m_ I _n.
⑵ The sealing of the cylinder is better. This can further reduce the amount of air leakage and ensure that the gas has sufficient combustion temperature and pressure at the end of compression, and the compression pressure of the cylinder shall not be lower than 8_0_%_of the standard value_.
⑶ It is required that the matching clearance between the engine and the running parts is appropriate and well lubricated.
The battery should have enough starting capacitance, and the technical condition of the starting circuit is normal.
(5) The starting oil quantity shall meet the requirements, the injection quality shall be good, and the injection advance angle shall meet the requirements.
(6) Use fuel that meets the requirements
