ungsten inert gas welding (TIG welding) is another welding process that uses electricity to melt and join pieces of metal. TIG welding was invented in the 1940s to meet the challenge of welding magnesium and aluminium in the Californian aerospace industry. Since then, its popularity has grown phenomenally. This is largely due to its versatility, cleanliness and minimal finishing requirement. And its suitability for welding so many different metals. Read on to learn more…

TIG welding (aka gas tungsten arc welding or GTAW) is a sub-type of gas metal arc welding (GMAW). Although equipment details have evolved since its invention, the general principles of TIG welding remain unchanged.

TIG welding isn’t the easiest welding technique to learn and master, nor is it the cheapest. However, it will reward the effort you invest in mastering it. Make no mistake; the results that can be achieved with TIG welding really are amazing.

Parweld XTM 221DI 5-in-1 Multi-Process MIG Inverter with AC/DC TIG, MMA and Plasma Cutting

XTM 211DI Parweld Multiprocess – MIG Torch, Argon Regulator and MMA Lead Set Package
The Parweld XTM 221DI is a 5 in 1 multi process inverter for MIG, AC/DC TIG, stick Welding and even plasma cutting!  With a click of the appropriate torch switch, this clever machine quickly changes to the process required.  That’s no changing of torches, polarities or gases to change process, just pull the trigger of the MIG torch for MIG welding, then pull the trigger on the plasma torch to start cutting.   Need to TIG weld Ali, no problem… Just press the TIG torch button or foot control to TIG weld with HF start.  You can have both Argon and Argon Mix and compressed air plugged into the machine and the inverter will switch between the gases automatically based on which process it detects is being used. Great for workshop use where space may be limited. A multi language, digital display is easy to set up, with minimal knowledge required.  Enter the material, type and thickness for the process being used and the machine will set itself to optimal settings which can be tweaked as required.  Rather set up manually?  This can also be done. MIG Torch supplied comes with an amperage control on the handle.  A remote control socket on the front of the machine also allows for use of a foot control for amperage control for TIG welding.
Features:
  • Auto polarity switching inside. Changing the work lead connections on the front of the machine is a thing of the past.
  • Instant swapping between MIG , TIG, MMA and Stick Welding processes available with one touch of a torch trigger, thus perfect for a versatile workshop, able to switch between any job or any part of a job with the press of a button.
  • Modern, multi-language digital user interface/display, alongside simple and intuitive selection options, allows for easy navigation through the synergic programs on board. Appropriate for workshop and sitework.
  • Save and recall job function settings for any desired process.

Parweld XTT212Di AC/DC 200A Pulsed TIG Inverter Dual Voltage

£740.00 ex.VAT

Parweld XTT 212Di AC/DC Pulsed TIG Inverter 110/230V

The Parweld XTT212Di is a dual voltage Pulsed Digital TIG inverter that can be used in both AC and DC modes for TIG or MMA welding.  As a result, this machine can weld of virtually any metal. One of our best selling AC/DC TIG machines, the Parweld XTT 212 offers plenty of features whilst being offered at a great price point.  Build quality is good and the addition of an amperage control on the TIG torch is a nice touch to get you started without having a foot control straight away. The XTT212 is a single phase machine, perfect for home or light industrial use and perfect for on site work where only 110V can be used. Supplied in the XTT 212Di P1 package is a TIG torch and regulator making you almost ready to go, with the addition of PPE, gas and some consumables. Square wave AC output and power pulsing maximises productivity whilst reducing heat output. This means you can weld fast without fear of burning through your work piece. The majority of steels can be welded in DC mode quickly using the pulse power function. The AC mode allows the welding of aluminium and magnesium alloys. The square wave output and adjustable frequency maximises the arc energy offering high welding speeds when coupled with the power pulsing function. The beauty of this machine is in its versatility, offering the benefits of a 230V workshop machine with the flexibility of 110V site machine. Compared with its cousin, the XTT202 AC/DC, the Parweld XTT212Di TIG Inverter is 40% smaller, but packs the same punch. Simple intuitive one knob control allows for rapid program setting. The XTT212 TIG inverter works with digital and analogue on torch current controls and has a foot control option.  Water cooled option also available. The P1 Package comes with a 3 Button Amperage Control as standard on the PRO26 TIG torch, eliminating the need for a foot control pedal, and putting the control at your fingertips.
INTERFACE
Featuring a highly intuitive multi language digital interface with one control knob offering Synergic TIG welding functionality.  As a result the setup process only requires material type and thickness details (while in synergic mode).  The system will then use the information supplied to set the welding parameters accordingly.  Synergic mode can also be switched which provides the option for manual input of welding parameters for the more experienced welder. Synergic TIG functionality is quite a unique and is often only found on MIG welding machines.  However it is a highly beneficial function to have on a TIG welding inverter as it makes setting your machine for the job in hand so much easier.   Parweld XTT 212 Di Pulsed AC/DC 200A Inverter Welder - Front Panel Image
