Our brand new RAZOR MULTI 230 AC/DC 4-in-1 is here. As the latest and greatest addition to our RAZOR line, this machine can do any kind of welding you need it to. MIG, High-Frequency AC & DC TIG, as well as STICK, no matter what you’ve got planned, the RAZOR MULTI 230 AC/DC can do it.

Please note that due to the size of this item, the free delivery is to the Australian capital city metro areas.  If you are outside of the metro area, please contact us for a freight quote. 

Key Features:

  • Dual Plug Compatibility (10A & 15A) - Connect to any 10A or 15A outlet for even greater versatility. 10A mode limits the output of the machine to 200A, whereas 15A mode allows use of the full 230A in MIG.
  • Smart Fan Smart Fan diminishes noise, saves power, helps reduce energy costs, and minimises the number of contaminants being pulled through the machine.
  • Power Factor Correction (PFC) PFC gives you maximum electrical efficiency and automatically compensates for any voltage fluctuation.
  • Job Memory The job memory function allows you to enter and store weld parameter settings under job numbers. Weld parameters can be further adjusted and stored as required. A total of 20 Jobs can be memorised and stored for recall.
  • 5” Colour LCD Screen Change settings with ease with the intuitive screen controls and nextgeneration user interface.
  • Generator Compatible Going off the grid? The RAZOR MULTI 230 AC/DC can be connected to a generator, we recommend one with at least an 8.5kVA rating for 10A mode, 10kVA for 15A mode.
  • IP21 Rating Rated IP21, so it’s protected from touch by fingers and objects greater than 12mm, and water spray from a vertical direction.
  • Wireless Foot Control Ready This machine supports the connection of both a wired or wireless foot control for extra versatility and convenience while welding. You can adjust your amperage hands-free to avoid disrupting your torch movement, and the wireless option reduces cables and adds greater manoeuvrability as well.
  • Dual Gas Input With dual gas inputs for MIG and TIG gases, you can keep the machine setup for both processes, saving you time during setup when swapping between processes.

  • Spool Gun Connection:
  • Wired & Wireless Foot Control Connection
  • Burnback Adjustment
  • Wire Inch
  • Inductance Control
  • Crater Current Control
  • Thermal Overload Protection


MIG Features:

  • MIG Smart-Set™ Setting up for a weld has never been easier, just set your wire, gas, joint type and material thickness and you’re ready to weld!
  • Complete MIG Weld Cycle Control Get complete control over your MIG welds with a full set of adjustable parameters, such as pre- and post-gas flow, arc ignition speed, and burnback
  • Spool Gun Ready This machine is Spool Gun ready, so you have the option of attaching a Spool Gun to run softer core wires such as Aluminium MIG wire. You don’t even need to change the setup of your existing torch or drive roller. The Spool Gun lets you quickly switch over to get the job done with no downtime
  • Crater Fill Finishing a weld has never been so easy with Crater Fill. It’ll ramp your welding current and voltage down at the end of a MIG weld so you can fill it in at a lower power, eliminating craters and pinholes. End your welds as strong as they started.
  • Gas-shielded & Gasless Wires This machine supports both gas-shielded MIG and gasless MIG, meaning you can run mild steel, stainless steel, aluminium as well as flux-cored MIG wires.
  • Inductance Control Change the frequency of your short circuit MIG welds with the Inductance settings, so you can choose your preferred arc characteristics.
  • Arc Start Starting a MIG weld has never been so smooth with the Arc Start dual function. Set above 100% and the Hot Start gives you a boost in current at the start of your weld, eliminating issues with starting on cold metal, and makes welding on thicker materials easier. Set below 100% and Soft Start helps with edge arc ignition by starting at a lower current and ramping up when welding away from the edge.
  • Geared Wire Drive This machine features a geared roller drive unit, providing consistent and smooth wire feed, and it helps when using longer MIG torches.


TIG Features:

  • SpotPlus™ SpotPlus improves the spot welding mode by applying an adjustable synergic pulsed program. The program speeds up the spot tacking process and is perfect for sheet metal fitups with gaps.
  • ArcPlus™ ArcPlus keeps the volt amps constant by adjusting the welding current proportionally as the arc voltage increases or decreases during a weld. It helps give better puddle control when weaving, reduced heat input and increased side wall fusion.
  • TackPlus™ TackPlus allows you to preset a tacking procedure to reduce the time required for tack welding, and also reduces the heat input in the joint between tacks, improving the quality
  • FusionPlus™ FusionPlus is an advanced AC TIG feature that provides greater arc focus at high welding speeds, and provides deep penetration even at low AC frequencies.
  • AC/DC High Frequency TIG TIG weld aluminium without issues with AC. High Frequency TIG (H/F TIG) gives you more control when starting or stopping the arc and reduces the risk of contaminating the tungsten or the weld.
  • Full TIG Weld Cycle Control Maintain complete control over your TIG welds with the RAZOR MULTI 230 AC/DC. The high frequency AC & DC TIG welding modes come with a full set of adjustable parameters, including pre- and post-flow, up and down slopes, as well as pulse. Everything you need, right at your fingertips
  • TIG Smart-Set™ The easiest way to set up for a TIG weld, simply set your filler material, joint type and material thickness and you’re good to go!
  • Mix AC/DC Mixed AC/DC welding is the combination of TIG AC and TIG DC- in one weld. Mixed AC/DC gives you faster welding speeds, better penetration, a faster weld puddle on cold workpieces, and allows you to weld on thicker materials.
  • Tungsten Optmiser Optimises the welding arc ignition in AC TIG based on the chosen tungsten diameter.
  • Heat Control Trigger (HCT) Mode Heat Control Trigger Mode lets you set a base current, which you can switch to at any time during a weld by pressing the trigger button. Heat Control Trigger Mode is great for manual heat input control as you go.


STICK Features:

  • MMA (STICK) You’ll be able to weld anything, including cellulosic electrodes.
  • Pulse MMA (STICK) Pulse MMA (STICK) welding helps reduce spatter, improves heat control and allows for an easier removal of slag. It also improves the speed and efficiency of vertical up welds by eliminating the use of the “Christmas Tree” technique, while still maintaining root fusion.
  • Hot Start Hot Start increases the stability of your arc ignition, and prevents a lack of fusion at the start of the weld.
  • Arc Force Arc Force helps to keep the arc stabilised throughout the weld, by detecting any short circuits and increasing the peak current to prevent the arc cutting out or electrode sticking.
  • Anti Stick Anti-stick prevents your electrode from sticking to your workpiece. When the machine detects sticking, the current will shut off and unstick the electrode.

A very accomplished welder.

By: on 22 February 2024
I have been welding for a few years (1986-) I've used the other 'multiweld' units and found them lacking. Usually because they do everything but not everything well. However this unit, the Razor 4 in 1 230 really does work well in every area. I spent a long time researching 'Multi function' welders and this one came out on top, so I bought it. I'm very happy with it. The accessories are made to a professional standard, they feel right in the hand. The TIG handpiece even has a flexible neck, BONUS! The adjustments on screen are excellent, the adjustments are comprehensive. Pretty intuitive and easy to use. For anyone who is starting with theMIG, TIG or MMA the 'Smart Set' function will get you within cooee of the correct setting and then you can fine tune it. I can lay some really nice Ali welds with this on cast Ali, thick and thin Ali. I just works! I can't think of a better addition to a workshop. I had a couple of issues with the welder when I got it (it fell off the trolley). Unimig have an excellent and very professional service team in Perth who could not have been more helpfull. This gives me reassurance in the product, any issue will be dealt with personally and quickly.
