Burger Boat Co. has weathered many a storm in its 150-year history, often changing direction to incorporate new technologies and adapt to changing market conditions. When the pleasure craft industry sank in 2009, it went after commercial work, and in the process had to develop a program for working in steel, which it hadn’t done in five decades or so. With the new process came new consumables from ESAB.

Q: I would like to know if a wire-feed welding machine can double as a modest-amperage DC shielded metal arc welding (SMAW) machine if I attach an electrode holder to the output. I have been told that aluminum welding works well and is convenient using SMAW and DC. I have the aluminum roller kit...

Q: I just ran across the article you wrote about gas metal arc welding (GMAW) machines in the July/August 2004 issue of Practical Welding Today. Your article was very informative. I will be purchasing a welding machine soon and would like to know if a GMAW machine can handle a motorcycle frame. Any...

Q: I only have a 110-V arc welding machine, and I want to weld car panels, but I keep blowing out the metal. What can I do to stop this? Can I use aluminum rods? Dan F. A: You can use aluminum rods on aluminum only, and they typically are used only for really thick pieces, about 0.25 inch and...

Welders often ask me, “Can I dry welding rods in my oven if they have gotten wet?” and “Can I put 7018 welding rods in my freezer for a certain amount of time if they are old?” The 7018 electrode is a low-hydrogen rod, which means it doesn’t tolerate moisture in its flux. If you’ve...
