For beginners and hobbyist that don't need to invest a lot of money
I bought this mainly to cut. On 110V it spits and putters, but it will cut. On 220V Oh My! This thing cuts anything I throw at it. Angle iron, sheet metal and even an old rusty rail road spike. I am too lazy to read, but with a few iterations I was able to get clean cuts on 24 gauge painted sheet metal from my scrapped work bench. See my pictures. I used a circle jig from a cheap off shores company. Not to shabby for a guy new to plasma cutting. This thing cuts fast and clean.I am not a good welder. Heck I am a welder only by definition. i can get 2 pieces of metal to stick together. Most of my experience is flux core with a little of stick. Most reviewers and videos on Youtube don't talk much about the TIG. This thing is a nice compared to my Harbor Freight scratch start. With high frequency starting, its a dream. With some practice I am able to get a descent bead on steel. I wasn't able to start a puddle on thin aluminum. AL isn't easy with DC, but can be done. I need to practice an read more. I have not used stick, but from the time I spent with the TIG, it should do well.I anticipated and got the same minor issues as everyone else. Leaking barb on the inlet of the chassis.After dis-assembly of the lid, the barb can't easily be replaced. It is attached to a solenoid. The best solution I could come up with is using 7mm fuel line. It's not easy to find. You find it where German cars parts/service are specialized. I had some leftover from my VW days. After all said and done, I ended up using less than 2 inches. You will need more if you use a Argon bottle.Honestly this thing takes some finessing before its good to go. Here some things to note.POWER CABLEIt comes with one permanently attached. I was expecting a twist lock that I could disassemble and use the plug on my old welder. It comes with a 6-50 and the socket in my garage is a 14-50. Well luckily the welder comes with an adapter. That adapter and another one I had I was good to go.REGULATORIt doesn't mount in a convenient spot. To low and too close to the chassis for my fat fingers. I modified the bracket to be upside down to raise the regulator. The adjustment knob is now is above the chassis.I used some old washers to space the bracket out. My jalapeno fingers now can fit. This also gives me room to hit the power button. The bracket was flimsy, so I heat treated it and painted it. The fittings, eww. I think the regulator uses metric pipe thread (BSPT), but with enough pipe tape or anaerobic sealant I was able to get 1/4” NPT to work without leaks. My first regulator leaked out the relief port. Outstanding service from Mike. A quick message to Primeweld and I was sent a new one.LEAKING INLET BARBI anticipated and got the same issue as everyone else. Leaking barb on the inlet of the chassis.After dis-assembly of the lid, the barb can't easily be replaced. It is attached to a solenoid. The best solution I could come up with is using 7mm fuel line. It's not easy to find. You find it where German cars parts/service are specialized. I had some leftover from my VW days. After all said and done, I ended up using less than 2 inches. You will need more if you use an Argon bottle.FITTINGSThe supplied fittings will do, but make it cumbersome for switching between TIG and PLASMA.I ended up using Sharkbite 1/4” NPT connections and polyethylene tubing. I prefer brass pneumatic push-to-connect connectors but Sharkbite is all I could find at my hardware store. Keep in mind. I don't think the regulator is in NPT.

5.0 out of 5 stars AWESOME machine for the money!
Reviewed in the United States on November 28, 2021
Awesome machine for the money! I literally decided on this machine ONLY because of all the great reviews on their awesome customer service. Companies that truly take care of their customers are extremely rare, yet this one does. Bought it mostly for the plasma cutter function, and it works amazing on everything I cut up to 1/8” plate steel. Haven’t gotten to try it on anything much thicker yet, but I imagine it would do fine if you were on 220v, as I cut that running on 110v household power and it blew through it pretty dang easy. Also had some heavy gauge sheet metal, and it cuts through that nearly as fast as you can draw the line! And that’s on only 20A and 30psi. Then, I went and picked up an Argon tank and flowmeter to give the TIG a try, and my lord was I surprised. I haven’t really TIG welded in nearly 20 years, but this thing made it so easy to start laying beads. I was almost certain it was gonna run like a dog, but it proved me wrong and had an extremely consistent arc and ran smooth as butter. And this was my first bead in 20 years using some rusty angle iron I hit real quick with a grinder. And I’m not an expert Tig welder, I just played around with it years ago. Do yourself a favor, and purchase the pedal if you intend on using the Tig much. It will make your life so much better. I also went ahead and purchased the $30 kit of plasma consumables, cause it only comes with one spare set, and you’ll wish you had more when the time comes to swap them out. Came with a built in PSI gauge, a regulator/drier unit that mounts to the rear (some basic assembly required), arc stinger, ground cable, #17 Tig collet-body torch with several cups and collets, plasma torch, a 110v power adapter, vinyl tubing and fittings to hook up regulator/drier, and even about a 6’ hose with gas fittings to connect an Argon tank to the machine. For the amazing price of just $500.... you’re basically robbing this company. Haha. All-in-all, I’m extremely happy with this purchase!

5.0 out of 5 stars Great value for the money!
Reviewed in the United States on January 25, 2021
Pleasantly surprised when I opened the box. What I received must be an updated version with electronic switches, a separate argon inlet from the compressed air inlet and standard 6-50p (standard 220 welder plug) complete with 110 adapter plug. All of these things are items folks complained about in videos I have seen when deciding to purchase the primeweld unit, so it would appear that primeweld listens to the feedback. The AG60P plasma torch has a swivel ball on the cables/air hose to make it handle better. The switch is comfortable to use. The SMAW electrode holder is adequate and works well. I haven’t had a chance to get an argon bottle or tungsten to try the tig torch yet. Setup is easy and everything plugs in easily. The pilot arc plasma cutter is awesome and I have tried it on a scrap that was very rusty and paint covered. I only cleaned enough for the grounding clamp and it cut fantastically. I have cut 1/2” stick with it as well as thinner material. I even cut a brake rotor in two cleanly. I am still getting used to the settings but it cuts clean with only a little dross. With the SMAW setup I have run several beads on dcen and dcep both. The 6011 electrodes ran well once I could strike the arc. A lot of the issues are the fact I have only run mig and FCAW the last 10 years and have learned some bad habits. Like many others have said, the ground clamp is serviceable but I will likely replace it with a better ground clamp (only about $15 for a great one from HF). The leads are nice length and give plenty of room for movement. One really nice part is that you can leave the SMAW and plasma hooked up and switch back and forth. My old craftsman 20 gallon air compressor had little issue keeping up. If you are looking for a value three process unit, this one won’t disappoint. I am really glad this is the unit I selected and would buy it again.

Reviewed in the United States on September 11, 2020
Update 10/6:
Customer service has worked really hard to make it right for me and shipped the part, second day air.
At the end I feel they deserve a five star for their commitment. I would come back to them again for the future welder machine needs.
About the machine itself - I'd say say you cannot go wrong. Any tool can occasionally break, but what matters at the end is the customer support.

Update 10/1: after less than 30 days of ownership - machine broke.

About a week back, the plasma cutter stopped working - pilot arc went dead and no arc, Except if scratching.
Called support on a Saturday evening, and was told that on Monday they will ship me a new torch part

Is now Thursday evening and no indication of part being shipped to me.

Basically the thing has lasted less than one project and expected support is not what was promised.
Returned it today, despite wanting to love it.

--- Initial review ---

This is a review following my real world cutting experience of a sheet of 17FT of 1/4" steel.
This is the first plasma torch I ever used or owned. Previously I watched some youtube videos with them.

I decided to pull the trigger on this plasma cutter, when my steel supplier for a landscaping project quoted me about $500 extra to cut me two rectangular triangles of 195" x 30".

I used a 3.9 SCFM@90PSI Makita compressor and ran the current at 50A (max), using a solid 220V outlet wired directly into main panel. I used two clampmeters to measure the actual DC current going thorough plasma torch. A Fluke and a Craftsman - one said 42A, the other said 47A. Perhaps the truth was in the middle. Say 45A, while setting was at 50. Not a big deal.

I did cut in perhaps 2ft increments with a 30 sec pause in between so I can reposition myself to the plat being cut.
It took me about 20 minutes to cut the whole sheet (~17FT length), with pretty good results. My travel speed was at times a bit too fast so the cut was not completely through (user error), so I had to do a second pass at some places.

At any rate - I got the plate cut the way I need it, and next step is welding.

I am new to stick welding as well and tried the stick welding function of the the machine also. I can do decent MIG welds, but stick is yet to be mastered. I am sure I will get to a decent level with this machine as well.

Overall I am very pleased with the machine for the little time I owned it. The three year warranty shall be good enough. Just make sure you do not expose it to rain or metal dust, as this is an inverter machine more sensible than a transformer one.

Update:9/12 - Have got to the point to lay a nice stick weld bead, i used 3/32 on 120v and 1/8 on 1/8 7018, 6011. I am no welder, but I can make some plates stick together now! I burned through about 3 lbs of sticks today with no issue and without hitting the over-current limiter

Good Luck!
