R-Tech 250 Amp Industrial Inverter Mig Welder (240v)

The MIG 250 is compatible with spool sizes up to 15KG. This makes the machine perfect for any industrial use without the worry of running out of wire in a hurry!. 

You can use both 0.8mm and 1.0mm diamters in the R-Tech MIG  250. We get excellent results when we use the follwing -

For anything 6mm and below, such as car chassis work or steel structures, we would recommend 0.8mm wire thickness. This is because the wire requires a much lower amperage to achieve briliiant penetration and prevents burning holes in the work piece.

For anything 6mm and above, such as digger buckets or RSJ's, we would recommend 1.0mm wire thickness. This wire thickness is a fantastic all rounder as it suites many of the users requirements.

If you want to weld any really thin material, such as car body panels or sheet metal, we do stock the 0.6mm rollers for the MIG 250. The machine works extremely well at low amperages!. 

Our machines are fitted with a double grooved roller to suite both 0.8mm and 1.0mm wire. Simply unscrew the retaining screw from roller, turn the roller around to match the wire diameter and re-install the retaining screw.

We reccomend using a gas that contains 95% Argon and 5% Carbon Dioxide for any welding less than 6mm. If you are welding anything more than 6mm, we would suggest an 85% Argon and 15% Carbon Dioxide mixed gas.

Yes you can. We highly reccomend using a spool gun when welding aluminium as this prevents any snags and birds nests found when using just a teflon liner in the torch. Our MIG 180, 250 and MTS 255 come spool gun ready, keeping the process nice and simple. Just plug the spool gun into the R-Tech machine and away you go!.

Note - Pure argon gas is required when welding aluminium.

Yes you can, the MIG 250 is fitted with stick welding functionality and will comfortably burn rods up to 4.0mm smoothly. This makes the MIG 180 suitable for agricutural welding jobs such as digger buckets, railings and gates posts.

We recommend setting your flow rate between 12 to 15 litres per minute (LPM) when MIG Welding. You can do this on the regulator supplied with the machine however, we suggest getting a flow meter for more precise tuning.

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 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 qelding 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 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.

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.

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.
