first of all i'd like to say that my primary language is not English. I found a thread that almost similar to my situation but since mine is more specific,.. bla bla(I don't want to confuse anyone due to my noobish grammar ). I managed to get A's for my 2nd semester on welding class. I know how to weld but totally clueless when choosing the right components,materials and current settings. as the title says, i would like to ask
1. can I use higher current than its recommended rating? the lowest current I can pull down is 70-80A (40-65A for 1.6mm electrodes AFAIK).
2. which electrodes provide more efficiency and easy to use on 1.0mm 1"x1" square tube(brand new,clean)?6013, 7014 or 7018? I've tried 2.5mm and 2.0mm 6013 all seems to no avail.
3. lastly...err...how to cover up these gap and holes caused by too much current(what they call it?burn through?warp? ) or..idk. just how to make these things look neat as it supposed to be?
any help will be much appreciated.
