Alphatig 200x TIG Welder #3- Welding Steel Sheet!

Haven't had much time to play lately.

Decided it was time to practice a little. Tried something different this time though- switched it over to DC to weld on some steel. With my old welder, this was NOT an easy process. It involved unplugging the high frequency box and taking leads out of it and then re-routing the leads to the correct lugs on the main welder. Might not sound like a big deal but trust me, it was a royal pain.

The Alphatig- Click two switches. Wow, that was easy...



I changed the AC to DC, and the pulse to direct / flat / whatever it's called.


This thing welds steel BEAUTIFULLY. I'm a sucky welder as you can tell, but I was astounded by how easy it was to kludge pieces together. I didn't burn ONE SINGLE HOLE through the 18g sheet I'm using here. Compare that to using my little 110 wire feed where I couldn't run a bead longer than 1/4" without having to stop and let the metal cool, this TIG welder is AWESOME!

First nasty welds, getting it figured out.



Once I understood I could actually put some heat to it and not blow holes the size of Texas, I made some progress. Top is a lap joint, middle is a butt joint, and the bottom is just a bead ran on top of the metal.



The lap joint turned out really nice. Was giving a little forward-back motion as I went and it seems to have worked great.



Time for a little project! This would have been impossible to make on my wire feed welder. Cut a bunch of 2" squares out and tacked them all together. I should also mention tacking things like this together was a breeze. LOVE having the foot pedal.



Not real pretty, but all welded up.





Wish I could spend some time practicing, 'cause I really need it. Got a couple of bigger projects in mind if I can ever get caught up on everything else!

Alphatig 200x Tig Welder #2- Setup and testing.

Well I hauled it in to school and set it up. Right off the bat I noticed this...



Plastic grating was cracked on the back. This is sort of in the location of the dent in the box. Figured it was still superficial, so I hooked it up to test it out.

Random info on the side of the welder:



Only took about 25 minutes to get everything out and hooked up, but I did already have an argon tank with regulator for my old TIG welder. The new one is sitting on top of it...



Yeah, I know, it's a disaster. Temporary just to test the thing out.

Business end of the welder:



Dislike #1- This is the power switch. Its a breaker, and it's located on the very BACK of the machine. ???



Dislike #2- the torch spins in the handle where I'm pointing at it. Very annoying when trying to weld, kept tipping and dabbing the tungsten. Not sure what to do about that yet.



Otherwise it does some pretty cool stuff! I have watched dozens of videos and read from several different sources, coupled with my previous "experience" with the other welder. Here are the first couple of (pretty sucky) welds off of the machine.





Best one so far is the last pic, second from the bottom. Basically just trying to figure out what all of the different knobs do. I *love* having the pedal- even though I don't yet quite have the coordination yet to hold the torch, apply the rod, and keep the pedal at the right spot all at the same time. It's fun to be able to dial back the heat but just keep welding. My other welder I could only do ONE of those beads at a time, then I would have to cool the metal, and re-start. All of these I pretty much did one after the other.

Now I just need practice practice practice...

For reference- here's the regulator that came with the welder-



and the one that cost my $60 through airgas.



Several reviews mentioned the regulator as being "cheesy" although it seems to compare just fine to the one I already had.

Only have about 45 minutes of weld time on it so far, lots more to follow I'm sure!

Alphatig 200X Tig welder #1- a review.

Yeah, one of those "Cheap chinsy Chineese crap welders".



I've been sort of looking to upgrade my wicked old Century 5-star welder for about 2 years now. It's an decent welder- AC/DC, with a high frequency box, but its really a stick welder that I set up to do TIG. It simply will not work for what I want to do- weld thin aluminum sheet metal.

Finally had enough money that I've been seriously looking for a TIG welder for the last 2 months. I was hoping to buy used, get a decent older welder that met my needs- AC, foot pedal, and LOW amps. I have had ZERO luck finding one locally. I expanded my search to within a 4 hour drive and still couldn't find anything that fit my needs. Best I could do was a decent Lincoln squarewave 175, both out of my price range and too far away to be able to pic up.

Crusing ADVrider, I stumbled acrossed a post about the Alphatig. First thought- yup, junk. But dang, the price sure was good. Got to looking around and they have pretty darn good reviews.

Meh, I'll hold out for something good... and another couple of weeks pass by- while I'm still researching the Alphatig. Sounds impressive. Oh, the 2015 model fixed a few of the minor issues (not problems, but added more features) from the 2014? And its on SALE? Why not.

$790, ordered on amazon.com late Friday night and it was here Wednesday.

 
This worried me a little...



But everything looks okay.



Included junk.



From the upper right hand corner, going clockwise: regulator, foot pedal, plug adapter to go from 220 style to 110, ground clamp, pack of cups, collets, and torch parts, stinger for stick welding, TIG torch and cable, and the infamous "manual".

The welder itself- LOTS of buttons and knobs!



So far, quality looks pretty good. No loose anything like you would expect from something bought at Harbor Freight. I can tell I'm not going to like the goofy cover for the knobs- but it pops right off so it'll probably just store it somewhere and forget about it.

More to follow!
