OXFORD MULTI-ARC COMPACT DUAL VOLTAGE
Ex. VAT

Oxford MULTI-ARC Compact - DUAL VOLTAGE - Heavy duty CC/CV   multi-process MIG + TIG + ARC             The MULTI-ARC compact (electronic) range are a real top performing workshop machine for MIG, TIG & ARC welding. Superb welding performance on all processes & precise infinite control of output power.

Built using our highly acclaimed hybrid chopper technology which uses a copper wound transformer & Mitsubishi PWM output control to give precise electronic control of the welding output. These models offer much more than any conventional switched MIG type welding machine. Firstly on MIG you get superior welding characteristics with minimal spatter, a super smooth welding arc & infinite control of the output power. The output polarity can also be swapped for running gasless MIG & special applications. In addition you have TIG welding & MMA stick welding capability all of which perform superbly. Previously to get this sort of performance & functions you would have had to buy an inverter, but inverters are not particularly rugged or reliable. Our Oxford MULTI-ARC machines weld as well as the very best German made inverters yet tolerate real world conditions such as damp workshops, grinding dust, knocks & drops & overvoltage spikes on the supply without problems. The benefits of this hybrid chopper technology should not be underestimated, you get performance & efficiency comparable to a good inverter based machine but with the ruggedness, reliability & lifespan of a conventional machine.

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.
  • TIG welding with lift arc, welds steel, Stainless, even thin aluminium.
  • Digital meter shows output amps for easy setting & for BS EN1090 etc.
  • Very simple to set up & use, anyone can use it in seconds.
  • Built in automatic compensation for varying supply & long cables.
  • Generator friendly design (no blow up on unstable generators!).
 

MIG welding  - exceptional arc characteristics on steel, stainless steel & aluminium. The weld is really smooth & consistent with minimal spatter & can be used for welding anything from car body panels at 15A up to structural steel work. The welding power is infinitely adjustable on the front of the power source so you can get the exact setting needed for any job. An all metal 4 roll wire drive system is fitted to guarantee reliable feeding of the wire. The output polarity can be easily changed to allow self shielding gasless MIG welding. MIG welding performance is superior to any standard 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 this is designed to stop ‘machine gunning’ at the start, this is particularly advantageous on aluminium welding as it stops the ‘pop’ & subsequent burnback which is the problem associated with MIG welding aluminium. We also offer a spool gun & push pull gun to fit.

 

MMA ARC welding The high OCV & built in hot start guarantees fast arc up & the welding is super smooth & spatter free from the thinnest sheet metal right up to heavy profiles. Built in anti-stick cuts the current in the event of a short down to prevent the electrode annealing & allow it to free off easily. All electrodes can be used even cellulosic rods which most machines will not touch!

 

DC TIG welding with true lift arc start so your 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.

* Min generator rating is for up to 75% output power, for full welding power we suggest increase KVA rating by 40% Size approx. all models (excludes width of rear wheels but includes length of bottle carrier) W=360mm, H=660mm, L=820mm All ratings above are based on MIG welding, when using on MMA duty cycles reduce slightly, when using on TIG duty cycle increases slightly & input power reduces. Compliance with with BS EN60974-1, BS EN 60974-10, RoHS, weee registered & CE marked.
As standard every machine comes with a 3M input lead, 3M work lead & 1.5M gas hose.
