The Oxford Multi-Arc 470 compact is a multi-process machine allowing the user to weld anything.  The Multi-Arc range is a truly adaptable machine.  Sold as a power source with integrated wire feeder, it demonstrates excellent MIG welding characteristics, with minimal spatter and infinite control of output power.  The polarity can also be reversed, making the Multi-Arc capable of running flux cored wire for gasless welding.  The Multi-Arc can be used as a powerful MMA Arc (Stick) welder or purchase a TIG torch to use it for TIG welding (lift arc).

The Oxford Multi-Arc 470 compact is built using technology previously seen on the highly acclaimed CUTMAKER PLASMA machines.  Oxford call this their hybrid technology, which uses a conventional copper wound transformer, but with Mitsubishi PWM chopper technology to give infinite and precise control of the welding output.  Chopper technology has been around for a few years but has been reserved  for the most industrial equipment.  Oxford have changed that by incorporating it into their Multi-Arc machines.  Oxford state that this hybrid technology is not to be underestimated.  Performance and efficiency is comparable to a good inverter based machine but with the reliability, ruggedness and lifespan of a conventional machine.

Oxford Multi-Arc machines are designed to weld as well as the very best inverter welders available but with the added benefit of extreme durability.  Transformer based machines tolerate real world conditions such as grinding dust, moisture, knocks, drops and voltage spikes from the power supply.  Oxford claim that this technology many times increases the lifespan of a machine when comparing to a European or American made inverter welder.  Furthermore, these machines are highly repairable unlike some of the complex inverter machines out there. 

Main features & functions

  • True MULTI-PROCESS CC/CV welding machine.
  • Infinite control of welding power allows you to get any setting.
  • Infinite control of wire speed with powerful 4 roll drive fitted.
  • MIG welding superior smooth arc with minimum spatter right from 15A to max.
  • MIG welding with reverse polarity gas less wire & special applications.
  • MIG arc start circuit built in to start the weld fast & clean without ‘machine gunning’ when you pull the trigger.
  • MIG variable inductance for fine tuning the arc to suit the job or operator.
  • MMA arc welding function welds all rods including cellulosic 6010 etc.
  • MMA anti stick circuit cuts the power if the rod becomes stuck.

Oxford Multi-Arc 470 Options

MIG Welding – exceptional arc characteristics on steel, stainless steel and aluminium.  Welding is super smooth, with minimal spatter to produce tidy welds and a low amp range of 15A, it can be used to weld anything from thin car panels right up to structural steel work.  Welding power is infinitely adjustable on the front of the Multi-Arc 470 so its possible to get the exact setting needed for any job.  The fitted wire feeder features an all metal 4 roll wire drive system, guaranteeing reliable feeding of the wire.

An easily selectable reverse polarity function allows the user to use flux cored wire, for gasless welding.  MIG welding performance is superior to a standard step voltage MIG on all materials. Variable inductance control allows you to tune the arc to suit your requirements, this is used to minimise spatter and to control the arc from crisp through to soft. Lower inductance is used with thin wires for a crisp stable arc with maximum deposition & minimum heat into the work, increasing inductance softens the arc, reduces spatter & increases heating of the work. Built in arc start circuitry gives easier starting every time you press the trigger to stop ‘machine gunning’ at the start, which is particularly advantageous on aluminium.  The arc start stops the ‘pop’ & subsequent burnback which is the problem associated with MIG welding aluminium. A spool or push pull torch/gun is also available.

MMA Arc Welding – High Open Circuit Voltage (OCV) and built in hot start guarantees fast arc up and super smooth welding with spatter free results.  Suitable for the thinnest sheet metal to heavy profiles.  Built in anti stick function cuts the current in the event of a short down to prevent the rod annealing and allows it to be made free easily.  Suitable for all types of electrode including cellulosic.

TIG Welding – The machine becomes a DC TIG welder with true lift arc start to make electrodes last well. This is ideal for stainless steel, mild steel, copper etc & can even be used reverse polarity for TIG welding thin aluminium  up to 2-3mm. The arc is super smooth right through the range & can be used for welding metal from 0.5mm thick.

Model Oxford Multi-Arc 470 Compact
Amps range 15-470
Duty cycle @ 100% 320A
Duty cycle @ 45% 470A
Input fuse (slow blow) 25A/32A
MIG wire size range 0.6 – 1.6mm
Electrode size for MMA 1.6 – 6mm +
Min. Generator Size 13 kVA*
Input Voltage 400V
Approx. weight 110kg

 

* 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 intermittant tripping & in some instances you may experience intermittant tripping if using close to maximum settings. *The min KVA rating quoted is for up to 3/4 power output, to achieve max output we suggest increase KVA by 40%.

All ratings above are based on TIG welding, when using on MMA or MIG duty cycles reduce by 15% & input power increases a little.
Compliance with with BS EN60974-1, BS EN 60974-10, RoHS, weee registered & CE marked.

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