I have a older model Hobart 180 and welded the T Top for my 23" center console about 10 years ago. My son still has the boat and no problems. Its strong enough to stand on the top of it or hang off the back of it. It was built before I purchased the spool gun and modified my welder to use it. The spool gun would have made it much easier because you have to have your lead out without bends to feed the aluminum wire thru the lead without it binding. New clean aluminum works best also. Remember argon for your shield gas!

Yes, here is a video giving step by step instructions and there are also videos that do all the same steps on different machines (such as harbor freight welders) but are a bit more clear and easier to follow but exactly the same steps just things in different places so following both should get you the info you need.

It depends on the Aluminum you are trying to weld.
You may not be happy with the results if you are familiar with a Miller GMAW-P.. Limit on the 140 will be about 1/8" material with .035" filler.

The Hobart Handler 140 can weld aluminum with the correct shielding gas and wire but will be prone to bird nesting at the feed roller due to the longer length of the feed tube from the feed rollers to the tip. The 140 is not spool gun ready.
A spool gun will help to eliminate the feeding issues. I opted for the 210 MVP which is dual voltage (115/230 VAC) and can use the SpoolRunner 100 Spool Gun. The Miller GMAW-P. I have access to is not portable.
For most of my thinner Aluminum welding I use my TIG .
For me the key to a good weld on aluminum is the cleanliness of the base metal, preheating the pieces and clamp the pieces to a heat sink on the back side. Clean off the oxide with cleaner and a SS brush and clean it again with a SS brush right before you weld. see less

My 180 is a 220 machine so I cant say about the 110 volt unit. Sorry, no experience there. I can only tell you that I have welded some 1/16 th inch and I believe 3/32 inch plate on the #2 power setting but don't know what that would equate to on your machine without researching it. I have used .30 and .35 aluminum wire with mine. You could try it thru your lead with the lead laid out straight and test it first before investing in the spool gun. Hope this helps. Maybe someone that actually has a 110 volt machine will reply.

Yes it can weld aluminum. But you can't hook up a spool gun. It does not have wiring outlet for it.
