  • striker lighters

    what is the reason your supposed to use these contraptions to light the flame when welding? (not even sure its the proper name.)

  • #2
    Good question. I thought that part of the reason for the design is that it has that cup to form a pool of gas to ignite. This might work better than trying to light a stream of gas as it shoots past the flint.

    At the end of the project, there is a profound difference between spare parts and left over parts.

      Forming a pool of gas to ignite sounds good.

      I always thought it was to keep from having to juggle a match and the torch and the knobs all at once.
      And, of course, to keep your hand away from the upcoming jet of flame.

        I always just assumed that it was simply much more convenient than using an open flame made by a match or whatever.

          I know in alcohol one, the fire helps to heat th bottle to build pressure

            Cause if the jet of gas doesnt ignite, it can blow out the flame from a match or lighter, and then youve got flammable gas building up in the area. Cant blow out burning magnesium

              magnesium? no idea, is part of the striker magnesium? i never had one.

              i have always used one of these, but the pros seem to be using the striker and i remember reading somewhere that was the proper way to do it:

                Personally, I wouldn't light an oxy-acetylene torch with a hand-held container of flammable gas from the dollar store. Maybe in a pinch, after the butane was gone just for the spark, but better, and safer, options exist.

                  Well because they work. No flame to to blow out in a windstorm, can be operated with heavy gloves on, and not all have a cup on them. A good design reduced to it's simplest form.

                      At work we used this type exclusively. But we had to blow a hole in the cup to prevent gas build up and a possible explosion. With welding gloves on these are a lot easier to manipulate

                        You’re kidding right? Possible explosion? In a striker cup that’s open on one side?

                          Thought it was magnesium, could just be flint. Either way the sparks are more reliable than a lighter flame that could easily be blown out

                            Propane or butane lighters of any kind are deadly around welding. A hot spark can burn right through the plastic tank and cause a fireball. I remember hearing of a guy with a butane lighter in his shirt pocket getting severely burned when a hot spark landed in his pocket.

                              AFAIK the cup helps lighting. I know if there is any wind, I get the cup over the edge of the burner and then squeeze it. The mix is trapped in there and lights.

                              Dunni about a hole.... yeah it may light with a sharp pop, but....?????
