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.

Please note: Other upgrade options may be available. Please contact Customer Service at (847) 357-0700 to discuss your upgrade options.

Warranty Information: The Invertig 400 welder (machine only) includes a 3 year warranty, the Smart water cooler has an 18 month warranty, and the TIG welding torches are warrantied for a period of 90 days against defects in material and workmanship. 

IMPORTANT INFORMATION REGARDING TRUCK FREIGHT SHIPMENTS

The Invertig 400 SHIPS to any business/commercial address with access to a forklift in the Contiguous United States for a flat rate fee that will be applied at check out. If you choose to ship the machine to your residence, accessorial fees will apply (a residential delivery fee, a lift-gate service fee, and possibly a limited access fee). Accessorial fees vary by ship to location and by freight carrier. You may place your order online, but you will be contacted by Customer Service to arrange and pay for any applicable accessorial fees. To avoid additional accessorial fees, we can also ship the machine to your nearest freight terminal, where the carrier will hold your machine for you to pick-up. **Please note that if you have indicated that you do not need lift gate at time of delivery and the carrier drops the lift gate, you will be contacted to pay the additional charge for this service. **

Also, if your ship to address is in Alaska, Guam, Hawaii, Puerto Rico, or any other U.S. Territory outside of the Contiguous United States, additional shipping charges will apply and accessorial fees may apply. You may still place your order online, but you will be contacted by Customer Service to arrange and pay for partial shipping along with any applicable accessorial fees.


IMPORTANT INFORMATION REGARDING TRUCK FREIGHT SHIPMENTS AND LOST OR DAMAGED GOODS

KEEP ALL SHIPPING CARTONS AND PACKAGING MATERIALS!

Your truck freight shipment leaves our facility and is accepted by the freight carrier in good condition. The material becomes your property when signed for by the freight carrier. Our responsibility for the shipment ceases when signed for and removed from our facility by the freight carrier.

Inspect your shipment thoroughly as soon as received. If possible, unpack the shipment in the presence of the driver. If this is a "HOLD ON DOCK FOR PICK-UP" shipment, inspect the shipment prior to leaving the freight terminal. If you do not inspect the shipment for loss or damage prior to signing for and leaving the freight terminal with the shipment, then the freight carrier will claim that you damaged the shipment bringing it home. If you notice loss or damage, then you must note this on the freight bill.

We are willing to assist you in every possible manner in the collections of claims for loss or damage, but this willingness does not make us responsible for such collection of claims or replacement of materials.

Well made sandals
Nice sandal that works well for me, feet sit comfortably in the shoes. I’m a quadriplegic that needs someone to wrestle my legs while putting my shoes on for me. These go on fairly easily. I have short legs and the extra height of the sandals helps to reduce the pressure on the back of my legs while my feet are on the legrests. Also my ankles tend to buckle and cause my feet and shoes to roll over onto the side of my foot. The soles of the UGG Goldenglow are wide and flat, substantially reducing this tendency. As far as comfort and function while walking, I can’t speak to that.

So comfortable but only lasted 5 months…
Size: 9, Color: Sea Salt, Size: 9, Color: Sea Salt
I was hesitant to buy these without being able to try them on, but I’m so glad I did! They are incredibly comfortable. I am on my feet for a large portion of the day as a school principal and these feel amazing all day. They’re very adjustable so if you have feet that swell (or just fatter feet like me) these should be able to accommodate you. They are clunky but really cute! They’re also easy to clean. I’ve worn mine just about every day since I received them and can easily wipe them down with a wet paper towel to make them look new. They will occasionally trip you up if you’re not careful, the same way Ugg boots can do, but that hasn’t been a big problem for me. They’re very lightweight and versatile. Love them! Update: I probably just wore these too hard because today I was walking the school hallway and the shoe just snapped. One of the sides was completely unattached and within 30 minutes they were only on my foot by one strap. Super disappointed!! But I loved them enough that I ordered another pair to get me through until boot weather.

Great shoe, room for improvement
Size: 7, Color: Bison Brown
I wore these to a 2 day music festival and my feet were so comfortable dancing and walking all day. Got a little sore by the end of the night, but the only thing that would have been more comfortable would be athletic sneakers so that pretty good for such a cool looking sandal. Sizing is off tho. I am a 7-7.5, and I ordered a 7. Length wise theyre good, but maybe I have skinny feet because I had to strap the 3 Velcro straps as tight as they could go, especially the heel one. Maybe I would have been better going down a size because I want to have my feet feel super snug and secure in sandals, especially if I’m dancing. But overall great sandals and honestly I’d buy them again
