Re: Torch questions
The biggest difference between the 2 torches is the amount of heat you will experience while holding the torch. Water-cooled torches allow you to run 250amps on your machine for the entire duty cycle and your hand won't cook. The 17 is smaller and some find it easier to learn with due to dexterity. ...

Re: How do these welds look?
As a new student welder, your welds look good. They need to improve to be "great" but you know that. And time under a hood will bring that. Your top pass is not burnt in on the "left edge" (as you look at the picture). Remember, what ever you do on one side of the head, you do on...

Re: .021 tube welding help.
Ok thanks so just keep on practicing and try to figure out how to go 1/2 way in one pass and maybe weld a little hitter and try to go a little faster. You could slow down the wire feed instead of going faster. If you're learning to weld tube/pipe, angle matters and that a lot easier to maintain whe...

Re: Any Reason to Have Both MIG and TIG?
There's heaps of advantages to each welding process: Stick you can do outside with the wind howling, on rusty metal, and in a single pass on some pretty heavy metal. Try that with a TIG! MIG is absolutely faster, more "flexible" (as has been mentioned) and will tolerate "less clean&qu...

Re: Spot welding aluminum with TIG
I would say that you are using way too much heat. 150a for 1/16" and 3/32" is overboard. When you use a 1/8" tungsten, you are depriving the weld from some amount of heat as the electrode is consuming current. I'd be using a #5/#6 cup, 3/32" electrode, and probably a lot closer ...

Re: 1st tig weld, I think there is hope
I'd echo some of what Nail says. I'd say you're getting too much penetration. Halfway through that bead, your travel speed picked up too fast. Maybe back off the heat a bit, slow down to get the "right" amount of penetration without bulging through so much. There's no downside to welding s...

Re: Spot welding aluminum with TIG
Actually Jody did a video on this and used DC to spot tack aluminum. You can get penetration without the heat that melts and distorts thin aluminum. Search his website or YouTube videos for the tutorial.

Welding on "used" aluminum boats requires a great deal of cleaning first. Got to be clean, clean, clean, and then cleaned a bit more. Acetone wiped, then stainless brushed before welding. The pontoons are often pretty thin too, so heat control will be very important. You might experiment w...

Re: Lincoln 3/32" 6011 on Everlast Machine
You shouldn't really need the DIG function except for overhead welding, maybe some vertical uphill. A tight arc is always best with stick, you should "almost" feel the base metal. 60xx series rods burn off very quickly with a high deposition rate. It might be easier to practice with 7018 r...

Re: 7018 question
I'd offer you some opinion based input: Welding 1/8" rod on 110v is probably overtaxing your machine. While it may be listed as capable, its usually the outer limit of its performance. Hence, it may struggle to keep the amperage consistent all the way to the work surface. If you want to practic...

Re: What am I doing wrong???
The wiring melting will "sag" due to gravity. About the only way to overcome that is to whip across the middle and sweep up, letting the puddle fill in behind you. It still won't be as clean as downhill, but if you must go vertical up, it will help reduce the bulging.
