HTP® Invertig™ 251 DV AC/DC - Miller® (Dual Voltage 110/220):
The HTP Invertig™ line up has now been elevated to the next level!
This package is for customers who want the brand new HTP® Invertig™ 251 DV but would like to use their existing Miller® accessories -torch, ground clamp, foot pedal (14pin) and existing gas hose and flowmeter (please note that your Miller TIG torch will need the 35 Dinse connection with the side gas connection, if your torch is flow thru you will need a new dinse connection). When you order this package in the dual voltage option you get the Invertig 251DV welder, two adapters to convert the 5/8-18 gas fittings to 1/4BSP, and the 110/220 adapter cord.
Meet the HTP Invertig™ 251DV AC/DC – Americas most advanced AC/DC tig welding machine.
This is the one that broke the mold. HTP (High Technology Products) is continuing its legacy setting the standard in the welding industry once again. The new HTP® Invertig™ 251 AC/DC is the machine you have been waiting for! Of course, this machine is also Made in Italy just like all previous and current HTP® Invertig machines, excellent build quality and arc dynamic, packed with features that other manufactures have not even heard of yet. It features 1 amp starting and 250 amps max output and it comes with an easy to navigate menu displayed on a 5.1” Hi definition LCD Color Screen.
If you are serious about high end welding, you want outstanding results, you weld exotic or reactive metals, look no further. The HTP® Invertig™ 251 AC/DC has multiple ways to start the arc, you can use it with foot pedals, sliders, rotary hand controls, the TIG Button™. Thanks to our new Dynamic Power™ option you don’t really need a foot pedal anymore. You can vary your amperage simply by how close or how far you hold your torch to the workpiece. If you previously owned a blue welder of course all your accessories including your wireless pedal, cold wire feeder, orbital welding machine, etc. ALL those accessories are a direct fit, no electrical adapters or switching over of any kind needed.
In DC you now have options you never had before. If course you can weld regular DC TIG, nothing special, and you can pulse DC TIG, most machines can do that too, but now you have a Soft Pulse option also where you can pulse DC TIG without the annoying sound. Those exotic or reactive metals I was talking about earlier, don’t you wish there was an easier way to weld Titanium and Stainless? Well, now there is: DC double pulse. You have a high-speed pulse overlaid with a low-speed pulse, helping you to reduce heat input, HAZ, distortion and increase travel speed. We also revolutionized the way how you can hold parts in place with our new Fast-Tack technology.
In AC you have all the options you have ever wanted. You can choose from different AC wave forms, then you can “mix and match” choose one wave shape for the positive side of the wave and another one for the negative side of the wave. Of course, you can still adjust your balance and frequency to 400Hz (100 amps and less) and 200Hz (101-250 amps) and you have asymmetric AC as well, but now you can choose your zero-crossing current. This makes you puddle more stable and less aggressive. If you are looking to weld BIG stuff with this machine, we know how much heat it can take to weld thick aluminum and no matter if you use 100% Argon or AR/HE mixes we added a Mix AC/DC feature that will allow you to mix DC into the AC welding arc and help you with tremendous amounts of additional penetration.
