Oxford MultiMIG 2Pulse Synergic 271CS Separate Wire Feed MIG Welder

OXFORD MULTIMIG 2 PULSE SYNERGIC 271CS MIG WELDER WITH SEPARATE WIRE FEEDER – 230V

The Oxford MultiMIG 2Pulse Synergic is a 270 Amp single phase (230V) British built inverter double pulse MIG welder. Complete with separate 4 roll wire feed unit.  Ideal for everything from thin sheet metal work to light fabrication and agricultural work.  Reverse polarity for gasless wires, digital meters and stick welding functionality now come as standard on the MultiMIG range making them truly versatile bits of kit.

While offering the same benefits and processes of the standard Oxford MultiMIG range, the 2 Pulse synergic models also feature both single pulse MIG and double pulse MIG capabilities.  In single pulse setting more stable welds are produced with a significant reduction in spatter, creating cleaner welds with a higher deposition rate.  Single pulse setting is ideal for welding aluminium truck bodies trailers, chequer plate and stainless steel.

The dual pulse setting is characterised by two distinct pulses, during the welding process with the second pulse having a very reduced heat input into the weld pool.  The second pulse provides a cooling effect allowing the weld puddle to solidify to a degree.  This is advantageous as it is ideal for creating the ‘stacked dimes’ pattern normally associated with TIG welding, as well as creating cleaner welds with a significant reduction in spatter as highlighted in the single pulse process. The double pulse function is perfect for more artistic needs, as well as thin materials and positional welding.

The Oxford MultiMIG 2Pulse 271CS Compact also has synergic capabilities, with the option to synchronise the wire feed speed to the welding power, to maintain arc length.

A separate wire feed on these models adds extra versatility by allowing the power source to be away from the welding and grinding area and all the dust.  The wire feed units  are ideal for pulling around on casters or mounting on booms to increase reach.  A wire feed  unit can be added to the MultiMIG instead of the wire feed inside the welder or as well as.  If a wire feed is in the machine and in a separate feeder, the user can have 2 different wire types installed for a quick changeover. The 4X wire feeder supplied has a 4 roll all geared drive for smooth wire feed and is fitted with a spool cover as standard.  No electronics or controls are fitted in the feeder for minimal parts and maximum reliability.

Industrial machines, the MultiMIG range will weld steel, stainless steel, duplex, hardox, aluminium and alloys.  Super smooth welding characteristics with low spatter for perfect welds and instant arc starts without popping.  Run from a generator or mains, with auto compensation even for long extension cables or poor supply where voltage drop may be an issue.

2 knobs control welding output volts and wire feed speed, which are both infinitely variable unlike their transformer, step regulated predecessors.  A stable digital display shows welding power when setting the machine and exact values during the weld.

Fairly unique to Oxford is their range of higher amperage single phase machines, a sought after specification for those welding thick materials with the constraint of only a 230V mains supply.

BRITISH BUILT

When you think of a British built welder, you automatically think Oxford.  They have been made in the UK for over 60 years and they have built a reputation as workhorses.  They are simply built to offer maximum lifespan, providing reliability and excellent welding performance.  The newer inverter machines are no exception, they are hand built using only the best quality components sourced in the UK wherever possible.  Anything that can be made in house is made right in the factory here in the UK – inverter transformers, coils and PCBs, they even daw their own copper litz wire.

Size approx. 650mm H x 330mm W + rear wheels x 840mm long.

Wire feeder case size approx. 180W x 230H x 420L (9.8KG)

* Note the input fuse size on single phase models is a result of Oxfords calculations & tests, it is possible to use any of these models on a lower fuse size at lower welding power. It is recommended always using a ‘D’ type circuit breaker to avoid intermittent tripping & in some instances you may experience intermittent tripping if using close to maximum settings.

Output amps on MMA and TIG is the same as MIG.  MMA duty cycle is reduced by 2% for the 513 and up to 6% on the 271/273.

Why accept an imported machine when you can buy a top quality British made machine for a similar price?

Please note:  Oxford machines are built to order and may take 7 – 14 working days from order to be built and dispatched.  If you place an order online, one of sales team will be in touch to confirm delivery time scales.  Also note our returns policy for these machines on our terms and conditions page.

THE TBWS VERDICT:

We have been supplying the Oxford range of machines for a very long time now. They are just simply built to last! You just know that you can go to these welders, turn them on and away you go. Oxford parts availability is some of the best out there too. Also, in the event of needing technical advice, you can talk to the people that designed and made the machine!

Their latest range of inverter based welders have been very well received, keeping to their tradition of solid built workhorses. The addition of double pulse MIG welders to their range is great for those wanting that extra arc control!

OXFORD MULTIMIG CS INVERTER POWER SOURCE

There are many models of inverter on the market today from Chinese imports, to well made EU or US machines. EU/US made machines generally perform better & are more reliable with a longer life. However, the desire to cram more and more into smaller spaces with over complex circuitry often makes these difficult & prohibitively expensive to repair. Many of the lower cost imports are simpler in construction but have a short life, particularly in harsh environments. Some are plagued by unreliability & quickly end up scrapped. Welding machines may be used hard every day, but some customers may use occasionally. Little used machines often suffer more, possibly due to damp build up etc.
There is nothing worse than buying a machine, using it for a few days or weeks over 2 or 3 years then finding its failed & you have an expensive repair or must buy again.
For the last 30+ years our Electronic Engineers have repaired almost every fault going on all makes & models, Esab, Miller, Lincoln, EWM, Lorch, Migatronic, CEA, Cebora, GYS, Fronius, Stel, Kemppi, Jasic, OTC, Panasonic etc.
Welding equipment is never used in perfect conditions, damp & dirty workshops are the norm! This alone causes many of the problems. We have seen almost every fault possible; we know what works well & lasts well. We have applied that expertise into these models to give you something different from competitors products.
Firstly, we keep things simple. No microprocessor or over complex circuitry is fitted. A cooling chamber is used to prevent ingress of debris to the electronic components. We don’t parallel 20 or 30 transistors we fit only 2 IGBT modules – minimum parts & maximum reliability!
We make everything we can ‘in house’ including inverter transformers, coils & PCBs, we even draw our own copper litz wire.
From a serviceability point our inverter machines are simple, no need for an Electronic degree! We include diagnostic LEDs & test points, all

OXFORD machines can be maintained by any competent Technician anywhere in the world.
MULTIMIG models are actually simpler to use than an old style MIG, with just one knob to set the welding power & another to set wire speed.
A stable digital display is fitted which shows set welding power prior to welding, with exact values shown during welding.
Despite the simplicity we have included features to give you superb welding characteristics, with low spatter, instant arc starting (no popping or
delays) & full control over the output inductance & arc characteristics. 4 roll drive wire feed on all models ensures consistent hour after hour reliable welding.
In addition, all offer superb MMA electrode welding & lift TIG DC (with full switched control), also torch polarity can be swapped in seconds.
From a mechanical point MULTIMIG models have a tough galvanised chassis & front panel bash protection. Apart from handles & wheels almost no plastic is used in these machines. Protection class is to IP23, these can be used outdoors with basic protection from bad weather.
