February 18, 2009 youleth I got the leak stopped on the welding machine shield hose, thanks to Permatex #1, which we were not allowed to have on submarines, but we all kept a tube for emergencies. That shield gas tube will NEVER come apart! Share: Previous Post Having problems with leaks in my welding machine’s shield gas system. Next Post Got a lot done, but nothing on the car. Cleaning up, straightening up and organizing the shop. It pays to stop every once in a while and put things in order. I will accomplish much more, quicker, when I go back to work on the car.
