  • How long have R-Tech been established?

    R-Tech have been in the welding equipment industry for over 25 years, firstly providing a welding equipment repair service including warranty repairs for most major manufacturers and manufacturing custom welding machines for bespoke applications. 

    R-Tech Welding Equipment became a Ltd Company in 2007, we were previously known as Industrial Plant Repairs (I.P.R) and RJW Industrial Repairs. 

    We have used our experience & knowledge as welding equipment repairers for distributors and manufacturers to provide you with welding equipment designed for welders.

  • Why should I buy a R-Tech Machine ?

    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 in Germany & USA.

    We give a 5 year collect and return warranty on all our R-Tech machines, a true no quibble warranty.

    Fast turnaround of warranty and non-warranty repairs.

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

  • How long will it take to get my machine delivered?

    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.


    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 call and one of our friendly sales/technical team will answer your questions.

  • How does R-Tech achieve such good value for money?

    R-Tech sell direct to you so no need for "middle men". This also gives you direct fast and free support.

  • How are R-Tech welding machines built?

    As with all major manufacturers of welding equipment, the R-Tech range uses components originating from several countries. 

    The main part of our inverter range utilise 'Eupec (Infineon)' IGBT & power modules produced by American and German companies providing very high duty cycles with great reliability. With other components sourced from the Europe (internals) and the Far East (chassis and case components) from tried and tested high quality sources. 

    All final quality testing is carried out at our premises in Gloucester, UK.

  • How do R-tech achieve such high duty cycles

    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! 


    Competitors 200Amp Tig Welder with 60% duty cycle @140Amps.. So what is the duty cycle @ 200Amps?? 

    R-Tech Tig201 - 200Amps at 60% duty cycle - maximum output 200Amps!

  • What do I do if I need help setting up my machine?

    Simply call us and speak to one of our R-Tech experienced technicians on 01452 733933 who can help you with any aspect of your welding equipment from installation to final setup. 

    We also have many how to weld videos available below.

  • What is an Inverter Welder and what are the benefits?

    Inverter welders use new silicon based technology to produce their welding power compared to older style welders that use heavy copper/aluminium transformers and rectifiers. 

    • Inverters use much smaller transformers, so they are a lot smaller, lighter and more portable.


    • Inverters use a lot less input power to get the same output power than the older transformer type machines, so they consume a lot less electricity and therefore are greener to run.


    • Because Inverters output power is controlled electronically, you have infinite power adjustment from 0 - 100% so you can really fine tune these to you needs. On MIG welders sometimes setting 2 is not enough power, but setting 3 is too much. You won't get this problem with infinite power control.

    Aren't inverter welders unrealiable?

    • No. When inverter welders first came out many years ago, like any new technology they did have their problems. Nowadays inverter technology is very reliable, cost effective and has many benefits over traditional welders.

      At R-Tech we use ultra-reliable Eupec Infineon IGBT Power Modules and power produced by American/German companies which are ultra reliable and allow us produce high duty cycle welding equipment. To learn more about our power modules and to read more about why we use them please see the information page on Inverter Welders
