LTPAC2500 Lotos 5-in-1 250A AC/DC Aluminum Welder with 60A Plasma Cutter with pedal LTPAC2500I ordered the Lotos LTPAC2500 machine March 6, 2013 directly from Lotos. It arrived by FedEx on March 13, 2013. As of this date I have welded aluminum, mild steel, and stainless steel. The machine handles very well. I have cut 5/16" stainless steel with the plasma cutter, welded 5/32" 7018 and 1/8" 6011 and these worked well also. Setup is easy for any veteran welder. Instructions are there if needed. The foot pedal was included and seems to be heavy duty. Over all I believe this machine is the best welder I've owned including my Lincoln. There are enough controls on this machine to adjust for special welding circumstances. The machine is light enough to carry around and requires less amps than older style welders. Almost all necessary items come with machine including 220 plug (10-20P). You will need rods, tungsten, 100% argon, and air compressor to use all the functions it has to offer. Long-lasting/durability? Haven't had it long enough yet. I plan on adding to this review months down the line.
From a retired pipe welder.
Thanks for reading

I was amazed when I got the unit to see the small size, but high frquency inverter welders don't rely on large transformers. A conventional welder uses a "high slip transformer" which is terribly inefficient. So a lot of power is lost because of this. The small transformer in this unit is more than capable of doing the job as it rely's upon high frequency rather than brute force to do the job. Inverter welders are not only more efficient, but a lot lighter in weight. This welder weighs only 70 pounds and a conventional welder of this output would weigh about 250 to 300 lbs. Also having a plasma cutter built-in and not a separate item is doubly nice. The front controls seem to be somewhat complicated, but If you purchased a new high dollar machine of this calibre, it would have the same basic controls. You can control a lot of parameters with this machine. Cheaply built machines from a local supplier do not come with the ability to change as many parameters as this one does. Another nice thing about inverter machines is that they use about 1/3 less power to do the same job. Both the TIG torch and the plasma torch seem to have a good quality feel about them and if you have to go to a local store to buy tungston, tips or cups, you can use most Weldcraft parts. I do mostly aluminum tig and I really like the power this machinme has. I also have a wire feeder that works off of a standard welder so I can do it all, either mig or flux cored. Steel or aluminum. I also like the idea that the Company has an office in California and is relatively easy to get a hold of. After some serious time with this machine, I will write another review. Since this review, I have used my wire feeder, and it works great with the welder. I have used flux cored wire and I can precisely set the output. I am amazed at how well the machine remains very electrically very steady. I powered it from a generator and welded like a champ. Great machine.

I bought this because I had a big aluminum boat project. I spent a lot of time reading specs and reviews. I couldn't be happier with this unit; I have used it to weld aluminum, steel, cut ½ inch aluminum, cut 1 inch steel, and even stainless. The manual could be a bit better as far as setup - but most of the info you need is all over the web anyway - welding basics, this is an amazingly flexible machine! The machine has not let me down yet! I did install some quick connects to switch between argon and air fast, so when you need to cut something, you don't have to unclamp the hose every time.

I had been searching for a multi-function welder and was pleased to have found the Lotos 5-in-1 welder. This welder is very versatile and operates well, within it's parameter. I like the fact that it has so many tools available within one welder! It is very compact and not too heavy for what it is. It is convenient to have the different functions available in one device, as opposed to a separate piece of equipment for each function. With the addition of a welding cart (sold separately) the ease of use is increased by making the welder mobile! All the items I need are right there in a nice compact configuration that doesn't take up a lot of space in my cramped garage:) The only issues I had were with the plug not being shipped initially and it also came with the wrong plasma cutting torch. If you buy one make sure you check your shippment carefully! Other than that, they worked with me to fix and correct the issues.

I am not a welder, but my friend is a good welder and has a Miller Dynasty 200. I told him what I bought and he was very interested in seeing what it would do. One of the first things he mentioned was that he liked the high frequency start as compared to his. He also mentioned that the LTPAC2500 puts out a square wave(?), but ended up doing some really nice welds after he turned a few of the knobs. Overall, I think he still likes his machine, but I think he said his cost somewhere around $3,200 when he bought it. I believe he thinks this is a really good deal and it is great that it also has a plasma cutter.
I know I am very pleased with what it can do and even-though I can not weld as good as my friend, I was surprised that my welds didn't look as bad as I had expected. I have no regrets about buying this machine, as far as I am concerned, it is a great machine at a great price and doesn't weigh as much as I had expected (70 to 78 lbs I think). I also noticed that they sell 2 of the circuit boards for this machine which makes me feel better.
I look forward to learning to Tig weld and being able to cut things easier with the plasma cutter in this machine. Two thumbs up, and excited about my purchase!

I bought this about a 18 months ago for the plasma cutter and hoping to do TIG at some point in the future. I used the plasma cutter many times and it seemed durable. When it came time to use the TIG a couple weeks ago I setup and turned it on and BOOM sparks flew out of the box with no output. No output on tig and no output on plasma either. Tried to contact service, there is none.
I was told they no longer sell this model and there are no parts!!! Offered to sell me a new model.
I guess it is a disposable machine.
I would not advise a purchase of any LOTOS device.

I am a hobby welder: cars, tools for cars, and just started an aluminum tear drop trailer with this welder. I have the most experience with MIG. I have used a Hobart MIG, Craftsman MIG, Harbor Freight TIG/Stick, Chinese AC buzz box, and Purifion HD-300. This LTPAC2500 is nice. After buying this one, I found another welder with similar specs and offering more controls including wider range of frequency, but at a higher cost (Everlast 250EX). The higher frequency is supposed to offer deeper penetration, so if the quality is as good as this one, you might want to pay extra for the Everlast.
At first, I thought that the quality was low because the input power wires are small (12g I think), but at max capacity this thing should only be drawing about 20A so it is okay. The ground clamp and cable are okay and probably enough for most uses, but I am wary of 250A when I get to that some day.
The manual is terrible as it is short, multi purpose, and focused on other models. In fact, the design for this model must have changed since the manual was made. It has taken me a good bit of time fiddling with the machine, reading online, and watching videos to understand the controls and which ones work in which mode.
Mine came with a WP-17 TIG torch (same as my HD-300 and HF machine), which seems to be a pretty standard and common torch. The torch seems good except the line has a plastic/rubber casing that cannot handle heat! I accidentally left it on a deceptively hot piece of aluminum which melted the case and into the hose inside. My HD-300 came with a cloth like shell for its TIG line, which I might switch to because it looks more heat resistant. The connectors for the TIG switch (same as HD-300) and the pedal seem cheap. I try to be careful not to cross thread or otherwise damage those connectors. It looks like the WP-17 torch is only good to 150A so keep that in mind if you plan to max out to 250A.
The high frequency start generally works well.
The current adjustment knob is pretty sensitive or twitchy. It really needs a large knob for such a wide range. It is supposed to max at 250A on AC TIG, but the LED shows 247 as the maximum.
It has been working pretty well for my learning how to weld aluminum sessions so far. I will update after I learn to use the pedal and complete (or fail) the trailer project.
I like this welder and the cost on sale was great. I don't know why it is no longer available.

When I receved my inverter I was confused because the cord was not standers 220 colors and the manual I receved showed different colors than I had on mine. So I called the company and they couldent tell me either. So I had to pull the panals and figure ot out myself... after I got it pluged in it would not function properly (wouldent strike arks) so I called lotos again and they would not even try to trouble shoot it over the phone. They told me I woukd have to pay to have it shipped back to them $60 and they would try to repair it! I hung up and pylled the unit apart to find a pigtail ziptied to tight and half unpluged and a bad solder bridge. After correcting these issues theunit dose function but hase poor control under 75 amps also the plasma cutter has a weird quirk if yoy strike an ark and loose it for a second lije during a lift it takes about 10 seconds before the unit will attempt to reestablish an ark (usless for a cnc table) My advice is going to another company with your hard earned cash. Or if your set on this unit call customer service woth a fake problem befor buying and test there customer service it is atrocious!

Purchased a LTPAC2500 welder. I have been using the machine for about a year and am completely satisfied with it. I was pleasantly surprised that not only did it meet the advetised claims - it FAR surpasses them. I bought it for TIG welding, which it does very well, but have found myself using the plasma cutter more than anything else. Excellent value, I would recommend this machine to anybody in need.
