Please note that we are currently sold out of our Invertig 400-new inventory should be arriving by the end of June.

We designed the HTP® America Invertig 400 AC/DC for heavy use in industrial settings; applications of use include precision fabrication, motor sports and racing 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, 208V to 240V power, the Invertig 400 features 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 of 4 to 400 amps. The Invertig 400 showcases a rated output of 350 amps when run on single-phase and a rated output of 400 amps, with a remarkable 100% duty cycle at 300 amps, when run on 3-phase. Planning to run this machine on 220-Please let us know if you have less than 218 volts.

General Features

  • Automatically adjusts for input voltage: 208-240V on single-phase and 208-575V on 3-phase
  • Meters can be calibrated for certification
  • Smart water-cooler that only turns on when needed and stops the arc when it detects a low coolant level-please let us know if you plan to use this on 220 or 480 so we can correctly set up the water cooler for you.
  • The cooling fans blow directly into heat sinks and the circuit boards are protected from grinding dust and moisture by a special lacquer coating which makes the machine IP23
  • Cooling fans work on-demand; the fans only power up when cooling is required, reducing noise and eliminating unwanted grinding dust from being pulled into the machine while the machine is idling
  • This machine has High Frequency start with the option to change to Lift-Arc Start when you work around sensitive electronics where high frequency is unwanted
  • 30 memory programs allow you to save specific welding parameters for 30 different welding jobs
  • NEW -Air Carbon Arc gouging mode.  See below.

Stick Features

  • Arc-Force (DIG): Helps reduce "sticking" of the electrode
  • Hot-Start: For easy arc strikes
  • DC and AC Stick Welding: AC frequency and balance can be adjusted in Stick mode as well
  • Pulse Stick Welding: Makes bridging gaps easier, welds out of position better, and reduces heat input
  • NEW -Air Carbon Arc gouging mode. Air carbon arc gouging is a thermal cutting process of removing or severing metal by heat from a carbon arc. The process uses a carbon/graphite electrode, power source, and compressed air. The intense heat arc produced between the tip of the electrode and the metal workpiece melts and cuts the metal.

TIG Features

  • 350 amp output on 50 amp Single-Phase Circuit
  • Asymmetric AC allows you to limit Electrode Positive or Electrode Negative amperages separately, which gives you more control over heat input on critical welds
  • AC Balance: Adjustable from 10 to 90%; allows precise control of oxide removal vs. penetration
  • AC Frequency: 20Hz to 400Hz (under 100 amps) and 20Hz to 200Hz (over 100 amps); Helps reduce or enhance heat input and focus the arc
  • Three AC Waveforms: Soft Square, Square, and Triangular

*Upgrade options available, via drop down boxes above, for additional charges.

Excellent Rivals to Lovers!!
Format: Kindle
The tension and banter between Huntyr and Wold was delectable. I absolutely love the fallen angel and all of his flaws. Huntyr is amazing too being a badass FMC with some major trauma. The world building was great and I enjoyed the training aspect of the story. The writing was immersive and was in the story the whole time. The ending had quite a twist that I hadn’t anticipated and made my jaw DROP. Excellent job! I also loved the narration. Laura is one of my fave narrators!

OUTSTANDING
Format: Kindle
This was very, very good. The world is vast and characters are complex. There is a good plot with a whole lot going on. This is well written. Good twists and turns and some heart breaking moments. You will love these characters, they have heart and loyalty. I am hoping that there will be several more books. We've yet to see anything from the Sea Court but only a mention of them here and there. The Wood Court was given a quick couple of scenes, and only as far as some warriors, we've yet to enter their court and the Shadow Court, I'm not sure if they will be a force for good or bad, but they definitely will play a much bigger role moving forward. This is primarily the Ice and Air Courts. Told in multiple views, which I loved, it gives you a chance to see things from different eyes. There's alot of political maneuvering and deception. I loved it and will pick up the next book as it becomes available. If you like The Fae and the courts, you should love this. I think the author has mucn in store for us.

Definitely worth the read!
Format: Kindle
After taking a deep breath and taking in that wicked twist of an ending, I have finally composed myself. My first thought when I started this book was that I love Reyna's character. I was intrigued by her connection with her familiar and the Ruin that is plaguing her land. It came as no surprise that she took her sister's place in an attempt to protect her. When they reach the Air Court everything slows down. This is where it was iffy for me. First of all, I like multiple POV's in books however 7 is a bit much. It starts to interrupt the story line. I felt like I was finally making progress connecting with one character, then it was switched to another person. I felt they all had necessary or pertinent information but not necessarily were they all POV worthy. The only other thing that annoyed me was that Reyna constantly was " trapped." She would rush off without thinking, only to need rescuing. She is brilliant in a fight, but she really doesn't think through anything. Lorcan is amazing. I know he might be on the "bad" list, but his background is so interesting. Eislyn(Reyna's sister) is really so sweet, but calculating. I enjoyed her and Thane's dialogue. The author did an amazing job with the imagery in this book. Everything was so detailed it was easy to fall into the scene. I love unexpected twists and while part of the ending I expected, I wasn't expecting how it took place. All in all, I found it very entertaining and I am very invested in continuing this series. Favorite quotes: "The truth may be twisted but never false." "Who was she if she was not the enemy of the Air Court? What was her purpose of she no longer has that?" "In a war-torn land, love was always a lie."

Great Read!!! Great story!!!
Format: Kindle
The series is long, but Ms. Wolfhart does a fantastic job of weaving this tale while bringing so much to the characters. Surprises and plot twists along the way to keep you intrigued. There is some graphic sex, but is no way the focal point. Grammar was excellent (a rare find with a lot of self publishers) with only a few noted errors. I rarely give 4 stars, let alone 5.

Sadly, DNF
Format: Kindle
I read this thru KU. I LOVED the synopsis. And then I began reading... and it was a DNF at 68% after picking it up and putting it down several times because I really loved the main female character. *****SPOILERS***** Pros: The world is unique, intriguing and fun. The primary female character is bad-a** but not a b*tech or a mary sue. The primary female has depth. I really want to know what happens to her even tho it's been weeks and I don't remember her name. The villains to the point I read are pretty good -- an ever present threat of mysterious and possibly many culprits. Cons: Way, way too many points of view. I stopped counting at 7. It's the prime reason why I don't care about most of the characters or remember their names even when I like them. There's just too many points of view so almost none of the characters have enough book space for the author to properly develop them. This literally killed the book for me. Actually it killed my desire to read. For weeks. The main male is more villain than hero. He agreed to marry the main female then locks her up & eschews her for her sister, all while bad mouthing her as unfit to rule when he never spent any time with her getting to know her. He is actually unfit to rule as he is blind to the woes of his own kingdom and starts off a peace mission to secure a ceasefire through marriage by murdering an inn full of people in her country for no real reason. Plus, he constantly makes promises he does not keep. And it's gross of him to pine for the sister behind the main female's back. ***** As much as I really wanted to see what happened to the main female character, it wasn't enough for me to keep trying to slog thru this book. There was a lot of potential here that just fell short. Hence, 3 stars.
