Hey guys, i looked in the search feature but can't get answers to the following questions. I have a MM 210 and have just bought a 3035 spoolgun to do aluminum. Most of the welding i do will be 1/8" square tubing to build a couple trailers and a headache rack for my truck. It will mostly be 2x2 or 1.5 x 1.5 tubing for the trailers racks. Now for the questions..
1) Does the metal need to be preheated? If so how - with a propane torch or something?
2) Do i use 4043 or 5356 aluminum. Whats the real differences with the two. Can i mix and match the two. If i have a spool of 5356, can it be used on a piece of 4043?
3) What does push/pull mean. I read alot about it but cant find out what it means. Is the push/pull gun the spoolgun?
4) And finally when welding aluminum, do i go from left to right, or right to left? Do i keep the arc in the puddle or away from it, thanks.
