I ran 75/25 gas, the k member was hot tanked but there was some oil still seeping out from between the flanges, I was also welding outside and a slight breeze could affect the shielding gas.
I did weld up the LCA mounts because the factory welds were crap, undercut in spots and poor penetration. Tim
Quote: Personally I wouldn't weld washers to the LCA points. The tubes welded into the K will do a fine job of handling and spreading the load. If there had been no tubes then that area would definitely need to be beefed up. Otherwise, nice job. If you switch to a mixed gas next time you need a bottle, you'll find a HUGE improvement in your weld appearance - there is virtually ZERO spatter with a mix. Additional cost ... shouldn't be a factor unless you're a production shop. The way I look at it, the time I save not having to clean up spatter is well worth any additional cost.
