I have a little dispute with a guy I work with, he thinks it is extremely important to bleed the lines on the mig welder when it is being shut down. I think this is a waste of time.
his argument is that the pressure (which is at most 20-25 psi) is hard on the lines. he says this is what he was taught, and that it also goes along with what he learned with scuba diving. but I can't find any info that agrees with this.
my argument is that I have never seen a failure of the gas hose or the regulator due to just shutting off the tank valve and calling it a night, and I had never heard this from ANYONE until he mentioned it. I have seen and worked with a number of machines, some that were close to 20 years old with all the original equipment that have ONLY been shut down by turning off the tank valve and leaving everything else set. It just seems like extra work and a waste of welding wire and time to me.
any thoughts?
