dbigK,
I am but lowly inspector and can only test accordingly to the whims and wishes of those further up the food chain and way beyond my paygrade. My limited trials with 7048 has yet to impress me.
The new plate ordered is 516 gr. 60. Yeah, and the other part of the gig is I'm dealing with Boilermakers/Tankies, and they are a high amperage, go gitter mind set. Granted, this is good from a pounds per hour point of view, but when it comes to old tank retro-fit....ah the horror! Fortunately, I'm working with UA pipefitters in a remote shop and this is just a partime/fill-in deal to help out the field division. Every time I come accross bone headed ideas like this, it reinforces my decision to have "hung-up the hood"! When you have to make a project like that fun, it becomes challenging...Herculean.
Thanks again for the input.
