First stationary job in my tent. I'm fabricating 9 Steel Columns, about 3.4 m long, from 6 meter long profiles. The three columns must be welded from two peces, the columns mainly carry the compressive load, but it is still worth welding them to full penetration. Cutting without a band saw with a large angle grinder with a little care, you can cut the profiles straight. For me, the most important thing is to properly clean the surfaces of the welded elements. I weld with a metal core MIG in an argon and co2 mixture. These wires give a very strong fusion and allow spray welding from about 180 amps. Welding with a solid wire in this case could be just as good for open root welding is better for me to weld with metal core wire. Often people ask me if this grinding helmet does not fog up. Generally it is ok but in such extreme conditions it would fog up in a few seconds. The mask does the job and the valve directs the exhaled air downwards and even in such difficult conditions there is no problem with the fog of the glass beyond the very edge, which does not bother you at all.
