BOC EOFY Welder Run-out. Synergic MIG 175A $861, 130A MMA $208 + more, Roller Bag by Redemption

110

In short, BOC are running out current model welders to suit a range of buyers. I'd had a little experience with MIG last year & have been looking to by a synergic model, ideally a multi-process unit so I could also learn TIG & stick.

Synergic machines seem to usually sell in the $1000-$1200 range for the bottom end units, so while it's only got a 20% duty cycle at 175A, this machine looked to be a real bargain for my needs.

Safety equipment is also on sale, so pick up a new welding jacket, gloves & helmet while you're there.

  • Does anyone know if this ones okay for car body panels?

      I've not welded anything that thin before, but based on the figures on page 35 of the user manual, the answer looks like a maybe at best.
      https://www.boc.com.au/wcsstore/AU_BOC_Industrial_Store/pdf/…

      Material thickness (mm) 1–1.6
      Wire diameter (mm) 0.8–0.9
      Current (amps) 45–80
      Voltage (volts) 14–16

      Material thickness (mm) 2
      Wire diameter (mm) 0.8–0.9
      Current (amps) 60–100
      Voltage (volts) 16–17

      The 175 I bought has a minimum 50A for MIG & a rated working voltage 16.5 to 22.8 V, so borderline.

      Hopefully someone who actually knows what they're talking about can help :)

  • I am after a multi use welder like this for home hobby and Ive been trying to find as much info as I can on the 175 welder.

    The one concern I have a there is no separate control for wire speed just a percentage voltage control within the setting, is that good enough?
    as I have been staring at this welder https://gentronics.com.au/collections/mig-welders/products/l… for a long while….

    • Theory is that the synergic welders manage this for you. Certainly the downside of this model is that there's no manual settings if you don't like the synergic program & range of available adjustment. By most accounts they'll produce a better weld from us amateurs.

  • Does this just run off a 10 Amp GPO ? I thought it said in the tech sheet it was a 28Amp input but it does say single phase ? so I am confused. How many Watts is it using ? I am off grid … I have a 5000/7000/9000W inverter (5 continuous, 7 for 20 mins and 9 for startup)

    I have no idea, I am looking at getting one and then having a boilermaker mate spend some time teaching me to do quick and dirty welding .

    • The small stick welder does. The MIG I bought has a 15A plug. I'm running it through a Ampfibian (https://www.bunnings.com.au/ampfibian-mini-15a-to-10a-power-…), but only got it this weekend so haven't tried anything like a long run at full power to see how long it lasts before cutting out. Fully expecting to get a 15A point put into the garage at some point, but will just run it at lower power or shorter runs until then.

    PDF catalogue here might be easier to read.

    • Thanks for that. I could not find the catalogue on the site for some reason.
