HTP's NEW INVERTIG 400

admin

Hi everyone, Just wanted to let you all know that HTP has officially released their new 400 amp TIG welder. We designed the all new HTP America® Invertig 400 AC/DC for heavy use in industrial settings, specifically for applications such as precision fabrication, motor sports and racing fabrication, heavy fabrication, pipe fabrication, aluminum fabrication, aerospace work and repair, along with work and repair in ship and rail yards. The Invertig 400 runs the following processes: TIG (GTAW), Pulsed TIG (GTAW-P), Stick (SMAW), and Pulsed Stick (SMAW-P). When connected to single phase 208-240V power, the Invertig 400 has the highest output of any welder on a 50 amp circuit — a full 350 amps of raw welding power. Additionally, the versatile Invertig 400 runs on 3-phase power from 208V to 575V, providing the full welding amperage range of 4 to 400 amps. The Invertig 400 features a rated output of 350 amps when run on single phase and a rated output of 400 amps, with a remarkable 100% duty cycle @ 300 amps, when run on 3-phase. If you have any questions drop them below as we would love to hear your thoughts!https://www.usaweld.com/Invertig-400...g400parent.htm Attached ImagesHTP America Inc.https://www.usaweld.com/default.asp847-357-0700Instagram: htpamerica_usaweldFacebook: HTP America - USAWELDYoutube: HTP America - USA WeldDrive a Lincoln, Drink a Miller, Weld with an HTP
Reply:So I gambled and bought one of these... just came in and feeling a little worried already. Background: I wouldn't consider myself a welder, just an ME that also welds. I recently started working at a small aerospace company that only had a Miller Multimatic 220. I've been doing a lot of thinner gage (~1/8" thick) aluminum on the side for the past few years with my Dynasty 210DX at home and also bought a 210DX at my last job. However, we needed much more capacity here for thicker aluminum parts so I was looking around at 400 amp machines. Was considering the Miller Dynasty 400, Lincoln Aspect 375, and the HTP Invertig 400. Company said go ahead and get a new welder, try to keep it under $10k. I like my Dynasty 210, but damn, $11k for the 400?! I probably should have went with the Aspect 375, but I interviewed with Lincoln fresh out of college in 2009 and they didn't hire me, so I've kind of had a chip on my shoulder since then when it comes to Lincoln. Couldn't find anything really negative about the HTP and it had an attractive price tag so I decided to give it a shot. The Millers I have bought in the past have came in fully assembled and bolted to a pallet, so I was a little surprised to see this come in with the cart/watercooler unassembled. This would normally just be a minor annoyance but the assembly instructions are crap. Really crap. The holes on the bottom rear bracket that holds the welder to the cart did not line up enough to thread the bolts into the welder, so I had to enlarge them slightly. Other than that, it went together fairly uneventfully. There are also ZERO instructions for operation of the welder itself. I also cannot find any manuals for the 400 online. I'll give additional feedback after I put some hours on it today.
Reply:That's odd, mine came fully assembled.   I didn't bother asking for a manual since I figured it all out within about 15min.  Post up your questions and I can try to answer them. 1st on WeldingWeb to have a scrolling sig!

Reply:Been welding a bit of mild steel today, seems to be doing a nice job so far. I'll have to dig some thick aluminum out and see what this thing's got. Also, I don't care how easy it is to figure out, there needs to be a manual for it, and a copy should have came with the welder. At minimum, a PDF copy should be easy to find online. I shouldn't have to post questions on a random welding forum. First question, why doesn't the amp readout change on the screen when I adjust it?
Reply:Yea, I hear ya.  Hopefully HTP takes note!  as for the amp readout on the LCD, it's because you have the pedal plugged in.  That is why it shows your minimum amps, because the foot-pedal is at it's lowest position.  If you disconnect the pedal, then the LCD display matches the red LED display right above it. 1st on WeldingWeb to have a scrolling sig!

Reply:Yea, I ended up reading through the 221 to familiarize myself with the welder terms/functions. Played around with the pulser on some thin steel tube caps which was easy to set up and worked well. First time using a Pyrex cup; I don't think I'll be able to go back! Definitely have to be more careful with the torch though as they seem to chip easily.
Reply:Originally Posted by LimitedSlip7they seem to chip easily.
Reply:Thank you for the constructive criticism. We will be making some changes to the shipping of the machine along with developing comprehensive assembly instructions. We are in the process of finishing the manual, we would like it to be as detailed at the 221 manual but this machine has many more features so it is taking longer than expected. If you have any questions or concerns please give us a call at 847-357-0700. Oscar did make a very detailed video on the functions of the 400, as that should give you a baseline. Hopefully the machine performs up to your standards and we are sorry for any inconvenience this has caused.HTP America Inc.https://www.usaweld.com/default.asp847-357-0700Instagram: htpamerica_usaweldFacebook: HTP America - USAWELDYoutube: HTP America - USA WeldDrive a Lincoln, Drink a Miller, Weld with an HTP

Reply:Originally Posted by OscarIt's ok, let him. This HTP subforum does not belong to HTP, it belongs to the whole WeldingWeb community (HTP does not moderate this forum, just the regular WW mods/admins).  There ain't gonna be deleted threads/posts like in the Everlast forum (which you won't see because they delete them, lol).
Reply:You don't know how Amazon works I guess. But oh well.  And for interrupting this thread, ask Oscar, who has connections to HTP, which they admit above with his early copy how many times he has done that to our threads. I simply made a correction to a claim that they make. Not trying to run down the product.  I'm sure it is a good product for the money. But folks like Oscar have been sure to put down our product in the past on our threads, and insert their own brand.Last edited by lugweld; 05-16-2020 at 01:51 AM.Esab Migmaster 250Lincoln SA 200Lincoln Ranger 8Smith Oxy Fuel setupEverlast PowerPlasma 80Everlast Power iMIG 160Everlast Power iMIG 205 Everlast Power iMIG 140EEverlast PowerARC 300Everlast PowerARC 140STEverlast PowerTIG 255EXT

Reply:Originally Posted by lugweldWhich is exactly what I corrected.  Because it isn't correct and a wrong statement. To be the highest output, it has to be higher than the Everlast, not equal to.  The Everlast puts out 350 amps on 47 Amps and the Stel, puts out 350 on 50A.

Reply:I don’t have a 400, but I do have a 221. All I can say about HTP is they are the only company I know where I got a call on a Sunday to answer my support question!
Reply:Originally Posted by lugweldWe do have a 3 ph version available.  But I didn't correct or say anything about that, other than the erroneous claim they made.
Reply:Received the following e-mail from a potential customer inquiring about the availability of the 221 when we were our of stock:"When will the invertig 221 with water cooler be available. I do not want or need the dual voltage machine. 220v only with a water cooler.  My crappy everlast 325ext just blew the inverter up and I'm done with them. Hopefully you can help me in getting an htp as I have read it's a great machine.  Thanks for your time. Chris."I then followed up with the potential customer once we were in the position to ship welders:Sorry I had to buy something to get me up and running.  I bought a miller synchrowave 210 and not very happy with it. I may finish this project and sell it to buy the htp from you. I've used the htp and loved it.Jeff NolandDrive a LincolnDrink a MillerWeld with an HTPoh snap!    1st on WeldingWeb to have a scrolling sig!

Reply:Originally Posted by TraditionalToolworksBut this is where you're actually wrong. The welder only uses 36 amps on 3 phase, and it's able to get 400 amps and has a 100% duty cycle at 300 amps.

Reply:Originally Posted by lugweldIf you can't read what was posted, it was referring specifically to single phase 240V and at 50 amps input and 350 amps output. Even had the picture to go with it.  I cited only that claim.  Already getting messages about you guys.
Reply:Originally Posted by TraditionalToolworksAnd where is your 3 phase version? Certainly not the 350EXT you linked to, that looks like a single phase until only. Or are you saying that your 325EXT stacks up to the Ivertig 400?HTP has their unit in their warehouse and shipping, how do people get the green weenie? Do they put their best weld under their pillow and the tooth fairy brings it the next morning if the weld meets approval ?I also notice you don't include the HTP in your cross brand comparison on your 350EXT page.You guys at the green weenie factory are really deceptive. Actually they are most often their customers...I think that says something about the company in itself. Caveat Emptor.
Reply:Originally Posted by TraditionalToolworksYes, I can read, you just want to split hairs.This is what was posted.That is absolutely true, it says nothing about using the least amount of amps, it says it has the highest output of any welder. Are you trying to say that the 350EXT has a higher output? Is there a welder that can get higher output on a 50 amp single phase?And I believe their machine is able to get the highest output considering they can get 400 amps. Do you have a machine that can do that? If so, please show it.Nope, I don't think anyone missed it, Jeff is a stand up guy, IMO, unlike the green weenie crew. Had you not come in blasting your mouth off, Jeff wouldn't have posted that.And you sure earned that comment from Jeff. Are you doubting he got an email that stated that? Seems factual to me. If you use a tissue when you blow your nose, you won't end up with snot all over yourself.

Reply:I have no dog in this fight but Jeff Noland and HTP have the best customer service of any company I have ever done business with.  For the record, I do not own any HTP machines but I buy equipment and consumables from them.  I recently purchased a conversion kit for my Hobart 120 Handler with original piece maker mig gun.  I had several questions and sent an email to HTP.  Jeff answered every question I had including some of the emails I sent late at night.  In fact, I joked with him asking if he ever sleeps.  I needed some nozzles for my Bernard Q series mig gun on my Miller 252 which were available from other vendors.  I sent Jeff an email asking if they stocked them which they did not.  However, he offered to order them and the price was competitive with other vendors.  This was a small order but Jeff and his staff went out of their way to assist me as if I was their best customer....   As stated, Jeff Noland is a stand up guy who deserves my business.  Joe

Reply:Originally Posted by TraditionalToolworksJoe,I am a customer in that regard also and will even note, HTP pays shipping for all orders over $35 which is more than fair, considering that companies like Everlast don't even pay shipping if you buy a machine from them.

Reply:You can have the best customer service in the world but if you don't have a good product you don't have squat. I am an HTP customer and I am biased and I don't care. Here is the deal. My Htp MIG 240 has been going strong since 2002 and I beat the snot out of it (I think I replaced the liner once just because). My HTP micro cut 380 is still doing great since 2002 as well and all I did to that was replace the torch head last month. I hope to replace my Dyn 300DX with a Htp Invertig 400 in a year or so.www.tjsperformance.comDynasty 300 DXHTP 240HTP Microcut 380Hyperthem 85JD2 Hyd Bender and HF Hyd Ring Roller all in one =(Frankenbender)Bpt.

Reply:Since it sounds like both welders are equivalent, how about you send me a green and red to put to the test and do an honest comparison of. I have a few aluminum rod holder projects in the works I can test them on. The real comparison of the machines should be done behind a hood, not on paper.

Reply:I too went from an Everlast to an HTP221.  While I haven't used the HTP enough to comment on longevity, I am very glad I chose not to support communist China with my purchase, since they have wrecked havoc with our lives and collectively cost us trillions in damages.  My purchases going forward will be based on the same consideration.
