R-Tech 180 Amp Portable Inverter Mig Welder (240v)
- Built with class leading Siemens IGBT's - Not inferior Mosfets
- Metal wire feed assy - Provides consistent wire feed
- Infinite fine control of welding voltage/amperage - What is this?Enables you to finely control the welding power in very small steps - traditional old fashioned MIG welders only had coarse voltage settings I.E Setting 1 = too little power, 2 = too much power
- Provides very smooth low splatter welds on all steels and aluminium due to its inverter technology
- 180 Amp Output, welding range 30-180 amps
- High duty cycle - 60% @ 150 amps, 35% @ 180 amps
- 16A 240v input required for welding at 180amps , 160 amp MIG output at 13A input
- Euro style MIG torch - What is this?Euro torches can be easily removed and replaced - they give a more consistent wire feed than permanently fitted torches as found on many DIY machines
- 5 year collect and return UK warranty - What is this?in the unlikely event of machine failure, R-Tech will pay to collect, repair and return the Mig welder to you quickly- No quibble warranty
- Complete package includes, R-Tech I-MIG180 MIG Welder, 3M MB15 Air Cooled MIG Torch, Earth Lead, Gas Hose, Mains Cable, Gas Regulator, Owners Manual
- Easy welding of aluminium with optional spool on gun. Note Pure Argon gas is required for welding aluminium - See the MIG Welder Spool Gun Videos

Can I run the R-Tech MIG 180 using a standard, domestic, 13amp plug?
Yes you can. Thanks to its fantastic inverter technology, the MIG 180 will generate up to 140amps smoothly on a standard household plug. This makes the machine perfect for welding up to 4.5mm.
-
Does the MIG 180 take 5KG spools?
Although compact in size to save space in the workshop, the MIG 180 will easily accept spools up to 5KG in size.
-
Which are the best wire diameters to use in the MIG 180?
You can use both 0.6mm and 0.8mm diamters in the R-Tech MIG 180. We get excellent results when we use the follwing -
For anything 2mm and below, such as car body work or steel structures, we would recommend 0.6mm 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 3mm and above, such as chassis work, we would recommend 0.8mm wire thickness. This wire thickness is a fantastic all rounder as it suites many of the users requirements.
Our machines are fitted with a double grooved roller to suite both 0.8mm and 0.6mm wire. Simply unscrew the retaining screw from roller, turn the roller around to match the wire diameter and re-install the retaining screw.
-
Which Gas Do I Need To MIG Weld?
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.
-
Can I weld aluminium with an R-Tech MIG Welder?
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.
View our videos on how to weld aluminium with a spool on gun -
Can I Stick/MMA Weld with an R-Tech MIG 180?
Yes you can, the MIG 180 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.
-
What should I Set My Gas Flow Rate When MIG Welding?
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.
-

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.

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.
