R-Tech 211 TFT Digital AC/DC TIG Welder 240v

R-Tech Easy mode takes the guesswork out of TIG welding. You normally had to enter all weld settings before beginning to weld on manual welders, we have done this for you.

You simply select the following from easy to understand screen.

Tungsten size
Material thickness
Filler rod material in AC (4043 or 5356)
Material type in DC (Mild or Stainless)
Type of joint - Butt - Lap - Corner - Tee - Edge
Pulse Off/On
Trigger / Pedal mode

The machine will set main amperage power , post flow gas time required and also advise on the recommended gas flow in LPM and ceramic cup size for torch.

Easy-set is ideal for all users - the beginner / occasional / proffesional welder as you can get welding - no need for charts / remembered settings etc as it's all built in for you.

You also have 10A trim +/- of recommended amperage, simply turn knob to decrease / increase amperage.
This is to allow fine tuning to personal preferences like travel speed, weld bead appearance.

Our TFT machines have advanced features to control the fan and water cooler.

Fan control system

The machine has 3 fan control modes.

ON - Fan on all the time.

MODE1 - Fan by thermal sensor.
The fan will stay off until the inverter temperature monitoring system switches on the fan to cool the machine down and stop when cooling has been sufficient.

This saves on power consumption and also gives a quieter working environment.

MODE2 - Fan on arc ignition.
The machine will start the fan as soon as an arc has been established, it will continue to run for 1 minute after you have finished welding - giving a quieter work enviroment and saving power.

Water cooler control system

The machine has 3 water cooler control modes.

OFF - No power to rear 240V aux power outlet.

ON - Water cooler on all the time
The machine will give 240V continuous output to rear power outlet.

MODE1 - Water cooler on demand
Water cooler is turned on when the arc is started, it will continue to run for 1 minute after you have finished welding to cool torch down and then turn off  - giving a quieter work enviroment and saving power.

On the TFT range of machines we added many new advanced functions compared to our previous digital machines. SPOT and TACK weld were two of these additions.

TACK welding allows you to product one single fast tack weld for a selected time when trigger is pressed. You can also set a stitch time which will then set a delay time after first tack and then another tack weld will be started and this will be repeated for as long as trigger is pressed.

Ideal for quick tacking of a job before the main welds are done, each tack will be excatly the same.

Tack time is adjustable between 10ms - 250ms, stitch time 10ms - 250ms

SPOT welding allows you to product one single spot weld for a selected time when trigger is pressed. You can also set a stitch time which will then set a delay time after first spot and then another spot weld will be started and this will be repeated for as long as trigger is pressed.

This is setup in same way as tack weld screen, however spot time is between 0.1s and 10s and the stitch time is 0 - 5s.

This allows you to control the amperage when actually welding which is very beneficial especially when welding aluminium or exotic steels / alloys. It acts like a car throttle controlling the amperage.

You simply unplug the torch switch plug from machine and plug in the foot pedal.

You then set the main control amperage on machine front panel to the maximum you wish the foot pedal to go to on a maximum depression. So if you set the main amperage control to 100amps, when fully depressed the foot pedal will give 100amps. If set to 40 amps, it will go from minimum amps to 40amps allowing fine control of amperage. 

Note: Some competitors foot pedals have the maximum amperage knob on the side of the foot pedal, so it can be hard to see what the maximum has been set and also easily knocked as on floor, this is quite an old fashioned way (we changed to machine control of foot pedal max amps over 17 years ago) 

Once a weld pool is formed and you are moving along the weld as the heat transfers into the workpiece you may require less amperage as the weld pool width / penetration will get too hot, reducing the welding current with foot pedal will stop this happening.

Over a 300mm long weld, you may need 100amps at the beginning and only 80 amps at the end of weld. Using a foot pedal will give you a uniform weld bead size.

It also allows you to back off the heat from weld if you need to reposition torch / get new filler rod but don't want to stop the weld I.E When doing pipework etc which requires one continuous weld.

Most experienced tig welders prefer to use a foot pedal especially on aluminium and exotic steels / alloys, unless the welding is not being done at a workbench i.e. working on a car etc.

Duty Cycle refers to how long a machine will operate for before it automatically stops the welding ARC to protect its components from overheating.

A 60% duty cycle at 200 amps would mean that you are able to weld at 200 amps for a maximum of 6 minutes out of 10 before the machine shuts off to cool down.

Higher duty cycles at higher amperage indicate a machine is made from more high quality components, built to withstand the stresses welding places on them.

We believe on a minimum of 35% duty cycle, most of our machines are 60% at maximum amperage. Built to last, ideal for all users -  Industrial, D.I.Y, Home workshop. 

At R-Tech we believe in building machines to last, with minimum down time to our customers, so we fit the most reliable power modules and IGBT's available coupled with oversized heatsinks. Therefore our machines are able to work harder for longer! 

We also quote our duty cycles at machines MAXIMUM amperage unlike some manufacturers who sneakily quote duty cycles NOT at maximum amperage which can be quite misleading! Duty cycle is very important, 20% is not an industrial duty cycle.

I.E Competitors state on thier 200amp machine, 60% duty cycle @140Amps.. So what is the duty cycle @ 200Amps?? 

Welding Aluminum - When welding aluminum, you will be using AC mode.  We suggest using a foot pedal when TIG welding aluminum as it greatly increases your control over the arc. Easy-Setup you can quickly get welding by just entering thickness and type of joint and the machine sets it all for you, including the correct post flow gas time. Just set and go. In manual mode you have full contol of all parameters.

Welding Stainless Steel - You use DC mode to weld steel and stainless steel on this machine, using Easy-Setup you can quickly get welding by just entering thickness and type of joint and the machine sets it all for you, including the correct post flow gas time. Just set and go. In manual mode you have full contol of all parameters.

ARC Control -  This can be done via the torch switch or with a foot pedal so you can vary the amperage whilst welding, you have much more control  than you would have over a MIG welder. 

It also has many torch switching options, 2T, 4T, 4TS (ideal for pipe welding where you need to keep arc established whilst moving workpiece or getting new filler rod)

A Great All-Rounder - If you use a lanthanated tungsten, you should find it very straight forward to go from welding mild to stainless steel and then over to aluminum without changing a single consumable. Not only is a TIG welder versatile in the material it can weld, it is extremely versatile in the positions you are able to weld in, be this flat on a bench, vertically and horizontally.

Cleanliness - Welds produced by a TIG welder are extremely clean and should require no cleaning, this makes whatever it is your are working on, ready to go as soon as the weld is completed. As TIG welding produces no sparks, so no spatter. 

A Digital TFT machine will do everything an Analogue machine can do in terms of welding capability however they come with extra features to really fine tune your set up and increase productivity. These extra features include the following -

Memory Function -
All TFT digital models come with a 20 job memory function, this allows the user to save multiple pre-sets into the machine. This feature is particularly useful for the welder who finds themselves welding different materials and thicknesses on a continual basis. You simply choose the pre-set you have saved and away you go, no more remembering which position you had a particular dial in.

Easy Setup - On TFT AC/DC TIG Welders
We have released the R-Tech EASY SETUP in November 2023 - With over 200 programs built in - getting welding is the easiest it has ever been. No more looking at charts, videos for help or tiral and error, it's all built in for you.

SImply enter tungsten size, material type, material thickness & joint type (corner, butt, lap, tee or edge and the machine will setup correct amperage, post flow gas time and advise cermaic cup size and gas flow required. It is extremely easy to get great welding results quickly - no more guesswork - Ideal for both the beginner welding and experienced looking for quick setup and excellent results.

Colour HD TFT screen -
The most easist navigation system using colour screen, all options on traditional machines had ALL the machine setting on one panel which could be confusing. Now only thr equired parameters needed for weld selected are shown, making it quick and simpler to setup machine.

Power Factor Correction -
Gives lower running costs, it is a more energy efficient welding machine, cleans noisy power supplies & is 100% generator friendly increasing the portability of the AC/DC TIG Welder.

Lift Start And HF Start - 
Lift, which also known as scratch, start is a useful feature when welding close to sensitive electrical components such as ECU's, where HF (high frequency) can potentially damage these components.

Lower Range Amperages - 
Depending on the model of machine, amperages could start as low as 3amps in the DC process and 5 in AC. There isn't much out there which would require you to be welding at these extremely low amperages however, it works particularly well when pulse welding.

Fine Tuning Of Settings - 
With all digital machines, you can precisely dial in your amperages, pulse settings, slopes and frequencies. This is all displayed on the digital readout located on the machine. With analogue machines, you only have the dials and indicators to rely on.

5 AC Waveforms -
Advanced Square Wave, Soft Square wave, Triangular wave & Sine wave can be selected on the digital machines. By changing the amperage waves, you are changing how the amperages fluctuate and behave during the process
