Lake Maggiore  forms part of this border. As both Italy and the Switzerland are  members to the European Union, the land bo â¦ rders are presently open.dditionally, the Italian island of Sicily is less than 200 kilometers away from countries of Malta (an island country) and Tunisia (on the continent of Africa).
By Derek Odom. The first thing necessary for stick welding on aluminum is to have a machine capable of DC (direct current) polarity, and it must be capable of putting out at least 200 amps. If your welder meets these guidelines, you are in business. If you have a 120-volt, 140-amp machine, for instance, there is no way it will ever weld on aluminum.
Spot welding may require up to 90,000 amperes for thick pieces of aluminum. Maintain the current for a specific period of time. Weld times in spot welding can vary from 0.01 seconds to 0.63 seconds, depending on the metal thickness. Spot welding may be used on extremely thin pieces of metal, up to 1.25-inch metal plate.
