  • Can the wire feed be moved from the machine?

    The wire feed comes away from the main body of the machine making it perfect for jobs in tight areas or at height. Wire speed and amperage can be controlled directly from this section of the machine, preventing the need to have to go back to the main unit to make adjustments. 

  • Can I change the length of the interconnecting cable?

    As standard, the machine is fitted with a 5m interconnecting cable. You can double this to 10 meters that greatly improves the reachability of the wire feed unit. This combined with a 4m torch would allow you to work upto 14 meters away from the machine. 

  • How Long Will It Take To Get My MTS450SWF?

    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

  • Why should I buy a MTS450 MIG welder from R-Tech?

    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 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 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.

  • 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.

    Are inverter welders realiable?

    • Yes. 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.

  • 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 Tewkesbury, UK.
