R-Tech 202 Digital 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
Trigger / Pedal mode

The machine will set main amperage power and post flow gas time required. Just press trigger / press foot pedal and you are welding.

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.

In TIG Manual mode, you have full control of machine settings including.

Standard TIG settings

HF / Lift Start
Pre-flow and post flow gas time  0 - 25 seconds - Ideal for stainless purging
Start / End amps 3A to max.
Up / downslope time  0 - 10 seconds

Pulse mode settings

Pulse frequency 0.1 - 500 Hz 
Pulse Amperage 5 - 95 %
Pulse width 5 - 95 %

Tack weld settings

Tack time 10ms - 250ms
Stitch time 10ms - 250ms

Spot weld settings

Spot time 0.1s - 10s
Stitch time 0.1s - 5s

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.

All of our machines include everything to get you welding as quickly as possible, at no additional cost. All you need to do is add your selected filler wire and gas to get going.

All of our TFT DC TIG welders include the following, in the box, at no additional cost.

• 4M WP26 Air Cooled Torch
• Earth Lead
• MMA Lead
• Gas Hose
• Mains Cable
• Argon Regulator
• Owners Manual
• Torch Consumables, Including Tungstens

Additional items such as a Foot Pedal and/or Trolley can be purchased as an optional extra, in the drop down menus.

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?? 

R-Tech provide you with high quality welding equipment with easy useable features, at exceptional value with un-rivalled direct customer support.

All our machines are robustly built using the latest ultra reliable IGBT inverter power components sourced from Siemens Infineon in Germany & USA.

We give a 5 year collect and return warranty on all our R-Tech machines, a true no quibble warranty. We pay for and arrange collection, repair and return to you. General turn-around is 3-4 days, Can you current supplier offer such fast service?

We also offer a free loan machine service to get you back welding quickly and if arranged before 3pm, this can be delivered next working day for UK mainland.

10 year duty of care on spare parts - We keep a large stock of spares in our Tewkesbury premises.

We build our machines in a modular basis which ensures any future repair bills are kept to a minimum, unlike some manufacturers who build the internals of their machines on just one or two P.C.B's. We ensure ours are designed to have internal components easily replaced ensuring cost effective repairs.

All orders for R-Tech welding equipment received by 3PM will normally be despatched the same day for next day delivery to the UK mainland, UK Isles may take 48hrs.

Once your order has been placed, will will email you an order confirmation, then a despatch confirmation with tracking number so you can track your order. We mainly use DHL who will often provide a 1 hour delivery time to you.

Simply order on-line or by phone on 01452 733933.

If you require any advice on which welding machine will best suit your requirements, please give us a all and one of our friendly sales/technical team will answer your questions

R-Tech offer a 5 year collect and return warranty on the R-Tech TIG162DC

Our warranty is a no-quibble collect and return service, it means that in the unlikely event of failure we will arrange collection at our expense, fix the fault (normally turned around within 48 hours) and ship it back to you at our expense. 

No other UK welding supplier offers this high level of service. Ask yourself if your current supplier would give you this kind of support. 

As we are engineer's ourselves, we understand the hassle and cost of machine downtime so we always provide a very quick turn-around of all repairs thus reducing your downtime.

Some manufacturer's can take over a month to complete warranty repairs which we feel is ridiculous.
