I,m a retired Tool & Die maker. I kept some of my equipment for retirement & having fun just
making stuff. I,m no welder like some of you, but I can weld fairly good. Nothing like Jody for
sure. But I have been welding Tig, Mig & stick for many years off & on. Remember I,m a machinist
not a welder.
But I have searched the net on cheap China machines. I guess the price is why. But what inspired this
post is some guy on the net said this. He said a lot of the burn down on these machines was the routing
of wires in hot places, transformers & such. I,m no sparky by any terms, OK. But can any of you guys that know
electronics think these machines can be upgraded to give them more life?
Funny how Americans can up grade ANYTHING. I love Blue & Red believe on that. My mig & Tig are both MILLER.
I would NEVER sell ether of them unless I had to. But these new ones have gone past the old Transformer ones
I have. I really would like to be able to adjust frequency as you can not with the old transformers.
That is my only thing about the ole guy machines. But if you are not a good welder you can over come that.
I,m not that good. But it would be cool for us limited income guys for some way to make the china crap
last a little longer, than the report I keep hearing.
GOD I love this form & Jody for helping us with his knowledge. the net is so GREAT with forms as this.
Thank each & every one of you for helping this Ole fellow in my retirement. God bless you all.

I think it would be theoretically possible to do so, maybe as a pet project. It may mean starting with a new case (custom user designed, of course) so you could mount things where they made the most sense, add additional cooling fans or upgrade wiring, etc. If I had the time and a machine to start with, I think it would be something that I would try.
I like to explore new things and try to make things better. I know that there are many people on this forum that are more than capable of doing just that sort of thing. For me, it would be a "learning experience"....

Just because you can, doesn't mean you should. Your time would be better spent buying an older mig (of a known good brand) for a steal, that would form a solid platform and then fix it up.

There is, or should be a second hand market. I'd rather buy a top notch item that has done a few years than brand new junk.
There is always someone who bought something they couldn't afford or not using much etc trying to sell.
As for Chinese Tigs, its like most things out of China, the QA isn't always there. I don't think there is any common fault in any of them that can easily be addressed with an upgrade, I think its just a luck of the draw. Careless design/assembly/selection of components, take your pick. Could have a cap or mosfet blow, loose connection or dry solder joint or just plain old lousy design.

My first TIG welder was an ESAB 252, a beast of a machine and weighed a ton.
I am perfectly happy thus far with my chinese AHP Alapha Tig 200x.
Doesn't have quite the balls the Esab did, but it isn't 750 pounds and it isn't bucks.
I had it apart to adjust the HF start "points" and it looks well built to me.

Making my point clear: I have no problem with cheap welders in the right settings. But to me, there is zero point in taking a REALLY cheap welder and trying to make it better by chooching around with the electronics. (Buy old good or new reasonable and be done with it...)

There are some excellent products coming out of China, and some complete junk. The trick is figuring out which is which. Everlast products are made in China, and get mostly excellent reviews for reliability and customer service. I own one of their products, a MIG/Stick welder capable of scratch TIG, and I'm happy with it. AHP has been mentioned. They too, on the whole, get good reviews for the product. I can't speak to customer service, as what I've seen is limited and mixed, but a google search would solve that if I were shopping. There's another outfit from China called Cigweld, if I remember right, that was marketing to me because of my globalspec account. They market mainly to businesses, but are worth a look for the industrial/commercial grade stuff they offer.
Just thoughts...

One of the reasons I took a chance on an AlphaTIG is that I saw a gut shot someone posted. The interior appeared to be fairly ordinary circuit boards and capacitors. I know a little about electronics, so I'm not afraid to open the box up and fix things if I have to. To get a $700 multifunction rig, I am willing to risk it. I figure I have a 75% chance of being able to revive it if something in there gets roasted. I have oscilloscopes, a nice German soldering iron, all sorts of electronic components, and so on.
If electronics intimidate you, my advice would be to think carefully about buying Chinese with the hope you can fix it. You can probably do it with help from online forums, but you may not want to fool with it.
There's a guy on Youtube who blew an AlphaTIG up deliberately. He took one or two toasted capacitors out and replaced them with better ones in what he thought was a better location. Brave!

I just don't see a need for buying chinesium here, the local market is abound with high quality used welders.
Only if I prioritized mobility would I spring for a new machine, and even then I'd do everything I could to stick to kemppi or esab. I do know kemppi still has the majority of production in Finland. Not sure where ESAB makes it's stuff anymore, I understand they aren't even Swedish owned anymore so no idea if they got any loyalties to local production anymore, but their machines are still quality.
Still this old machine I got, it's an inverter, but simple electronics compared to most modern stuff, electrolytic capacitors are the main thing likely to fail on this and that's something that should be serviceable.

With Chinese, I got 120V capability, stick, TIG, and AC for $680 plus delivery. In my area, American with AC would have cost at least 2.5 times as much, used. I also got an inverter so I don't need a 100-amp circuit. The machine is light enough to put in my truck with one hand, too. I'm content with my choice.
I wish I lived in a place where people give good stuff away on Craigslist, but it doesn't work that way here.

My take:
I don't think I would buy any new machine with the idea that I would alter the guts to improve it. I might do something like that in the case of a really inexpensive used machine, but I work on high power electrical/electronics stuff for a living.
When faced with decisions like this I ask myself what sort of project am I looking for. Do I want a welder to weld stuff with, or do I want a welder to "BE" the project? Either approach is valid, it just depends what you want.
I don't own any of these Chinese made machines so I do not either defend nor criticism them. What is undeniable is that there are many, many people out there that have bought them and are perfectly happy with them and they do offer a lot of bang-for-the-buck. There are a few factory support horror stories around on the web, but you can find those for Miller, Lincoln, ESAB, etc too, if you look around enough.
For myself, after much mental anguish, I went with the Lincoln SW200 from a local welding supply. That way there is a front store window that I can throw the machine through if the service is really, really bad...

I have one of the earliest Everlast Power iMig200s. It is the very same machine Jody reviewed. As his shop got cluttered, he sent it to me. I used it very hard for several months in both MIG and MMA, and use it lightly now. I don't doubt I'll use it hard again, as it fits through a 16" manway, and I will have more of that work.
It's at least five years old. I've never had a single problem with it.

Steve great honest reply as Poland308. I have a Miller 200 transformer machine that is rock solid.
But as I said I would like a smaller lighter tig that I can move around. But the bad reviews I keep
hearing it makes a retired guy on a fixed income some what hesitant. Now $800 is not going to kill me.
But I have not heard from ones that have had them for a few years & had no problems. I,m looking
at the AHP 200 or Everlast. I know I could still get a lemon, but would feel better as to others success over
3 years, of moderate use.

Choosing custom TIG welding accessories begins with understanding your specific requirements. Consider the type of materials you will be welding, the thickness of the materials, and the desired welding outcome. Once you have a clear understanding of your needs, you can move forward and explore the following factors to make an informed decision.
1. Quality of Materials:
One of the primary considerations when choosing custom TIG welding accessories is the quality of the materials used in their construction. High-quality accessories are built to withstand the rigorous demands of TIG welding and provide long-lasting performance. Look for accessories made from durable materials such as tungsten, copper, and high-grade stainless steel. These materials offer excellent heat resistance and contribute to better conductivity, resulting in enhanced precision and efficiency.
For instance, when selecting tungsten electrodes, opt for those made from high-grade tungsten alloys. These electrodes have superior heat tolerance and longer lifespan, ensuring consistent and high-quality welds. Investing in quality materials may be slightly more expensive initially, but it ultimately saves you money in the long run by reducing downtime and replacement costs.
2. Compatibility with TIG Welding Machine:
Before purchasing any custom TIG welding accessories, ensure that they are compatible with your specific TIG welding machine. Different machines have varying specifications and requirements, and using incompatible accessories can lead to poor welding performance or even damage to your equipment.
Check the specifications of your TIG welding machine and compare them with the accessories you are considering. Pay close attention to details such as connector type, size, and thread compatibility. Ensure that the accessories you choose align with your machine's requirements to achieve optimal results and prevent unnecessary complications.
3. Size and Shape Options:
When it comes to custom TIG welding accessories, having a variety of size and shape options is essential for accommodating different welding applications. The size and shape of accessories, such as collets, cups, and gas lenses, play a significant role in achieving precision and desired weld aesthetics.
For example, if you are working on projects that involve welding in tight spaces or corners, consider choosing smaller cups and gas lenses that offer better accessibility. Alternatively, when dealing with thicker materials, larger cups and gas lenses provide better shielding gas coverage and improved weld pool visibility. Having a range of size and shape options in your arsenal ensures versatility and adaptability, allowing you to tackle various welding tasks confidently.
4. Ease of Use and Assembly:
A good custom TIG welding accessory should be easy to use and assemble. Time is valuable in the welding industry, and you want to maximize productivity by minimizing setup and assembly time. Look for accessories that can be quickly and securely attached to your TIG torch or torch body. Consider features such as quick-release mechanisms or simple screw-on designs that allow for efficient and hassle-free installation.
Furthermore, ensure that the accessories are intuitive to use, even for beginners. Clear and concise instructions, along with user-friendly designs, make the welding process smoother and more enjoyable. This is particularly important if you are new to TIG welding or regularly work on different projects that require frequent accessory changes.
5. Application Specific Accessories:
Different welding applications require specific accessories to achieve desired results. When choosing custom TIG welding accessories, consider the specific applications you will be working on and select accessories that cater to those requirements.
For instance, if you often work with aluminum, choosing accessories specifically designed for aluminum welding, such as tungsten electrodes with rare-earth additives, can improve arc stability and prevent contamination. Similarly, if you specialize in fine or intricate welding, selecting accessories like precision collets and smaller cups can help you achieve intricate details and precise weld bead placement.
By understanding your specific applications and selecting accessories tailored to those needs, you can enhance your welding results and efficiency, saving time and effort.
In conclusion, choosing the best custom TIG welding accessories depends on various factors such as the quality of materials, compatibility with your TIG welding machine, size and shape options, ease of use and assembly, and application-specific requirements. By carefully considering these factors and selecting accessories that align with your needs, you can enhance your welding experience, achieve better results, and improve overall productivity. Remember to invest in high-quality materials, choose accessories that maximize your machine's potential, and prioritize ease of use and application specificity. With the right custom TIG welding accessories, you can take your welding skills to new heights.
