taskmaster mig ????

hi, im brand new to welding, got myself a taskmaster 120/15 mig welder, the problem is it came with no instructions and can,t find anything on the net about it. i was going to try do some gasless flux cored welding with it but will have to rewire to reverse polarity first, question is can i do this and second question is does anyone know of the model or where i can find an instruction manual for this model.

It's a Cebora welder, and an old one at a guess - try searching the forum for Cebora or Snap On.

I suspect it will be hard wired for gas only. The gas/gasless ones have screw terminals at the ends of the power and earth leads allowing a swap. If it's all hard wired it's not practical to swap.

If it's just practice and you aren't welding nuclear power stations together just run the gasless wire in normal polarity. For thinner metal it's tricky to tell the difference polarity makes.

Post a photo of the front if you need advice on what the switches and knobs do.

thanks for the speedy reply, will have a search on those sites mentioned, was going to be using the mig for repaiing car bodywork, i have the option of using straight foodgrade co2 or going flux cored gasless, unfortunately reversing polarity would mean rewiring the machine internally however you recon id be ok using original polarity. or would co2 be better, bear in mind will be welding at awkward tight spots and all welding will take place outside in sunny scotland.

I'd prefer CO2 over gasless for bodywork mostly because you don't do bodywork in one go - it's all little bits. Also you can see what you are doing with gas shielding which is helpful for bodywork. Build a wind shield - the gas can be blown away.

But CO2 can be problematic on low settings. It doesn't support an arc on the low settings of some welders especially when you use 0.6mm wire. Go with 0.8mm wire and accept you will blow more holes.

thanks for help malcolm think im going to use co2, will give it a go with 0.6 wire of which i already have, if that doesn't work will get some 0.8. bit worried about all these holes im going to be making.
