Ladies and Gentlemen,
      Tried to post my power point presentation. Finally learned how to do it. Earned living in front of screen chasing welding etc. info on internet. Power Point presentations good info! Way that worked, Read the "blank" paper or screen "learning curve" done! Under the posting after completing  it there is "attachment" noted. Seen it one million times and added it up finally. My underwater wet welding back ground goes back more than thirty years ,  includes five patents and managing a job with thirty welder divers. Note step two , attachment Power Point presentation I made at our annual meeting in Las Vegas 2012 !   I presented at the  “Underwater Water Welding Cutting Conference“

One development is a gelatinous coating comprising particles of electrode coating and thermite suspended in a gel for use as an insulating coating and fluxing agent. Patents have run out on many patents. However, Andersen is available for consulting.”

Will answer underwater welding questions and appreciate getting such. I look forward to hearing from you.
                      Sincerely
