As long as you don't put the unit up against your stimulator and pull the trigger! ???

I have a friend who used to like to TIG weld.
He ended up with an implanted defibrillator.
His cardiologist observed that depending on the frequency of the TIG it might cause it to fire or adjust the frequencies of the device.
You might want to consider checking with your doc.

Unfortunately, all the doctors I've dealt with for my back problems and surgeries have long since retired. I've found most don't really have a clue and default to the conservative side.
Instead, I went to the manufacturer of my implant and found out there's little worry for me. A pacemaker might well be a different outcome.

Anyway, after much research, Iíve decided to go the cheap Chinese route and think Iíll be going with this model: https://www.amazon.com/dp/B08HT1CZDX/?coliid=I2RFNAELJ54UH6&colid=3BTJ1CQT4L78V&ref_=lv_ov_lig_dp_it&th=1
A cheaper model I was considering is here: https://www.amazon.com/dp/B08L889WBF/?coliid=I3I0SRDZ2XW07Q&colid=3BTJ1CQT4L78V&psc=1&ref_=lv_ov_lig_dp_it

Iíll go into the reasons for my choice for anyone else considering buying one.
ē   Usage: I donít anticipate using a plasma cutter all the time. If I did, Iíd probably opt for a better one with longer warranty and more features. This could change (especially if I go the CNC route), but this lets me get my feet wet with very little expense, comparatively.
ē   The only reason I chose the FlameWeld model over the cheaper one is the torch. The cheaper model doesnít list the torch type anywhere I saw, whereas the FlameWeld states itís an AG-60P.
ē   Torches: most of the review videos I watched that got fairly good reviews were on models with either an IPT-60 or AG-60/AG-60P torch. When I compared consumable prices, the AP-60/AG-60P torch consumables were much cheaper.
ē   CNC: the PrimeWeld and Everlast plasma cutters are CNC ready and are pretty much ďPlug-N-PlayĒ with various CNC plasma cutter tables like Langmuir Systems. That said, Iíve watched a lot of videos on DIY/open source CNC plasma cutter videos. I even found a video on an open source DIY torch height controller video.

In closing, while the plasma cutter Iím considering is cheap Chinese-ium, I can buy 3 of them for the price of higher rated ones. I also realized that pretty much all of them are built in China unless one opts for a bigger name brand like Hypertherm, Miller, Hobart, ect. and I canít say for sure they arenít built there as well.
If customer service, cutting thicker material, CNC ready, and/or duty cycle are more important, then going with the better brands is the better choice (IMHO).
As for the DIY CNC potential, factors to consider:
ē   High Frequency Start vs. Blowback Start: high frequency start models have a higher chance of inducing electrical noise into CNC components and controls. They are used, but be aware extra shielding may be required.
ē   Unless you are planning on only cutting clean, unpainted material, pilot arc is a must.

Hereís where the multi-wire, pilot arc models are a better choice over the single Euro style plug, in my opinion.  Many of the DIY CNC rigs utilize these wires for torch control and torch height control. Finding and sourcing the connectors to jumper in between the torch, control box, and your CNC controller is easy. Not so much for the Euro style connector without having to connect inside the main box. For general use, non-CNC applications, I really like the Euro style plug as it seems more rugged.

I'm still considering a couple things before committing, the biggest of which is supply and timing.
Based on the Mike Festiva video listed in my OP, I'm not really set up to "Run the crap out of it" like he suggests. I also liked the looks of the BestArc model he's reviewing in that video, but they are currently unavailable everywhere I've looked and don't list a price.
With the way the supply chain is going, I'm torn between ordering now while the one I'm looking at is still available or wait until closer to spring when the weather is better and see if other models like the BestArc come back in stock. Waiting has the added advantage of possibly finding a good, used, higher end model. In the end, it's a 50/50/90 dilemma.

Whatever you decide on just keep in mind if your thinking of waiting with the inflation going on the price of stuff is only going north.   The welder I was planning to buy last fall is $300 more now!

Thanks to the looters in Los Angleses, it's going to cost more!

Saw on the news this morning where they are breaking into the containers on the trains when they come through LA and stop for the next opening to proceed on. Un freaking believable what they are doing!!!

My material handler (fork lift driver) from way back in my factory supervisor days - used to drive long haul through the states and beyond. He drove for probably 25 years before "retiring" to factory life. He used to have all kinds of stories, some of which included driving through certain areas where you just drove through red lights and stops signs because if you stopped, you'd see your trailer doors swing open. And apparently you don't dare get out of the cab...

I realise that had nothing to do with plasma cutters.

But I have been following this thread. I am curious what machines are chosen. I don't do a lot of metal shape cutting, and if I needed to, Jonathan has a unit. I think one of the higher names, but probably a lower class machine... I can't recall.. hypertherm, something like that. I can ask him about it if anyways interested in his opinion? I'd call him a "uses it to cut some shapes, then doesn't use it for months on end till he needs to make a bracket or something again" type user.

If only some of you guys knew...  and yes, there are places like that where you simply do not stop, at least not after dark, and the cops will not stop or tag you for it either. Thankfully, I do not go to those places anymore!

Another one you may want to look at if you havenít already is the Lincoln Torchmate.   I know itís beyond your current budget and objective but the cross fire pro series tables are pretty cool if you decide to go to the next level.

Iíd love to have one but plasma in a basement not happening !!!

Not sure where this search wound up - but I used a plasma cutter for the first time ever, tonight.
Holy crap! Where has this been all my life...
It's the hypertherm powemax 45xp. My understanding is it's a deplorably expensive machine, but my goodness was it a joy to use... if the cheap ones work half as well as this, then I'm not sure how you could go wrong.

For me, where this thread ended up is by the time I acquired the materials I wanted to cut, the unit I'd decided on was no longer available. Go figure, just my luck.
The reason for waiting was the advice, from multiple sources, was to use the crap out of it as soon as you received it so that any issues with the product could be quickly addressed. Especially for the cheap Chinese models ordered through Amazon.
Even a close friend of mine told me that he and his brother had ordered 2 of the same units at one time. One worked great, but the other was junk out of the box.
I'd still like to buy one, but I currently can't find one with all the features I want that's in stock.
