SameI thought it was based on a 10 minute weld cycle, so you'd get 6 minutes out of it before it overheated, you'd have to do a pretty long weld to be going 6 mins nonstop!

You'd be surprised at how much welding 60% is... Also at 40degC ambient, which is rare for the UK unless in hot plant rooms etc. Granted SIP aren't a "premier" welding machine brand, but if user experience checks out... all good.250a @60% will mean you’ll be constantly hitting the thermal cutout if you’re doing long runs. Not good for the machine or your caffeine intake.
The very early SIPs and one or two of their "industrial grade" later machines were decent, but in general, and especially on this Forum, SIPs have a bad reputation. This includes their recent hobby-level inverter machines, which are overpriced rebranded generic imports, with typical reliability issues.Just on a side note I know the sip machines are generally not too well regarded I'm pretty impressed with my very heavy double drive rollers and 60% duty cycle at full 250amps is much better than most comparative machines in its category so I'm quite happy with it. I may end u buy a 2nd machine on the 2nd hand market
Yeah no problem I'll take some photos in the next few daysThe very early SIPs and one or two of their "industrial grade" later machines were decent, but in general, and especially on this Forum, SIPs have a bad reputation.

However, this HG3000 looks like a different beast. Any inverter with a 4-roll feeder and weighing 48kg must have something going for it. If you ever need to take the covers off, some internal photos would be appreciated.
I'm not that experienced when it comes to different machine specs, but that seems a really high duty cycle at max amps60% duty cycle at full 250amps is much better than most comparative machines in its category so I'm quite happy with it.
I seen one of those for sale the other day. Is yours still single phase and what's the duty cycle? What are the benefits of the separate wire feederI have the same machine with a separate wire feed and it's been great. Blow holes in 6mm when going full chit and dips in and out of spray with light gas. I'm getting universal next.
I've got a sip hg2600a MMA inverter and it's the same duty cycle 250amp at 60% I was using it this Saturday on 20mm plate with 4mm rods at 190amps and it ran rod after rod for an hour so I can believe the duty cycle.The very early SIPs and one or two of their "industrial grade" later machines were decent, but in general, and especially on this Forum, SIPs have a bad reputation.

Hi Henry thanks for the info I had never considered the heat would cause issues with wire feed. Its all starting to make sense now I know why some of the industrial welders I've seen have water coolers. I ultimately will need to do some test plates I plan on trying .8mm wire with the light gas (doubt it will have the penetratation on 12mm plate) in spray as this might be useful on 6mm plate that I usually just dip weld. I will also try spray with 1.0mm wire and light gas. Then I'll switch to a bottle of universal and try to repeat the above I might even post some pics of the individual samples on here as it might help someone in the future and all the folks on here can give there feedback.My two cents worth. If you want to get into spray, at lower amps use .8mm wire. If you are prepared to do multi runs then that is a solution. I use light gas for everything. In my training the technical college used light and we had to weld all test samples with it. I make some playground equipment using 10mm steel plate, on my 350amp machine that goes to 380amps on 1.2mm wire using light gas without any dramas.
I believe that your machine will give you spray on 1.0mm solid wire and you can fill quite a fillet with that, however progress will be slow. My 350amp machine (peaks at 380amps) now that I have gotten used to running at those settings is still a bit slow (horses for courses). My machine is 50% duty cycle at 350amps and has never stopped on thermal and I have tried. Even on hot days here doing 800mm long runs (on a rotator) 10 items one completed next in still no stop . Two problems, the heat, gloves get a roasting and the torch. I have had to resort to water cooled torches to get out the production that is required. I believe that you will have torch problems prior to having thermal problems. Once the torch gets hot you start having feeding issues. The up side is there will be no thermal issues . I have a 270amp machine which I have put a MB36 binzel gun on it and on longer runs still have feeding issues, using .8mm wire. Fitted the water cooled gun feed issues went away. There is a sweet spot for wire diameters, you can go outside those recommendations and still get a satisfactory result. Ultimately it depends upon what works for you
Thats a handy setup with the swinging arm and door track when I get a bigger work shop I'll be doing something similar. Do u do structural steel fab? Those are some seriously heavy stands in the backgroundView attachment 339730
Here's mine with separate wire feed and yes it will spray 0.8 wire with light gas
That looks identical to my Cros Arc 291cHere's a few pics of my machine for anyone interested.

They're quite a bit different to look at...?That looks identical to my Cros Arc 291c
Case, wire feed motor/gears/ quick wire feed switches look much the same to me, maybe same frock with different knickers?They're quite a bit different to look at...?
