The welder in this video is about as good as the information in this video. NEVER POKE YOUR ROD TO START AN ARC! STRIKE IT LIKE A MATCH! DRAG THAT ROD ACROSS YOUR WELD JOINT LET THE SLIGHTLY ROUGH SURFACE CHIP OF A MICROSCOPIC PICE OF THE ROD, GUARANTEED TO STAR THE ARC EVERY TIME!
My first two and really only two fears of welding underwater welding… electrocution and drowning… this video still doesn’t really answer the question, how do you change electrodes and not get shocked, I understand once the are is started, is there an on/off button the diver controls?
