Except for the AC ones, like that one that lives somewhere in the far east
A photo of the rating plate, or better still of the insides would confirm for sure.
I dont know how but i cant upload a pic in this forum.. then i will follow your advise to use that multimeter.. that mig of mine doest have logo... or company name to it.. its red colour.. and have stick and mig. Let say 2 in 1 mig machine...A very few MIGs are AC, they are sold as very cheap hobby machines and don't work very well at all. As we don't know the make & model of the machine in question there's no point in guessing.
As PDG says - could you post some photos? Show us the inside and front panels and logos and markings on the outside.
The giveaway would be the presence of a rectifier, this will most likely be in the form of an aluminium heatsink.
If it's a gas/no gas type with the facility to swap polarity it will be DC.
If you have an old-school analogue multimeter set it to DC and the highest range, pull the trigger and work down the voltage ranges to the 100v range. If you get a reading the output is DC, if you don't then it's AC.
Yup i do... mybe my file to large then...When uploading photos are you useing the upload a file button, next to the post reply button?
Its mig inverter 175i colour red. 2 in 1 sticjk and mig.If it's an inverter that does stick and mig then surely it's dc?

It is not second hand... and this thing are surely from chinaIt's an inverter MIG with the option of switching over to MMA. It will be DC output. Below the Euro Torch connector there's lettering saying MIG INV - I can't see the rest but I assume it says MIG INVERTER. Inside there's a DINSE socket for changing between earth +ve and earth -ve which is needed for using the machine with gas and using gasless flux cored wire.
I don't know what the 36V socket on the back is for. It may be to run the machine of 36V AC which is a safety mains in some parts of the world.
There are AC output inverters, but they are expensive and have an extra stage to convert the DC output into AC and they are used for TIG welding aluminium.
That welder looks a lot like this one, sold by IFL in the UK, but it will be a Chinese design sold under several names.

I find it strange that there isn't a data plate on yours giving duty cycles, mains input voltage and the rest. Is it second hand? If so the plate could have come off and it would explain why there appear to be a couple of screws missing on the back.
