Big Mistake
Forgive me everyone I have made a huge mistake. I purchased a Rossi 130amp welder generator not realising the amperage cannot be adjusted. It has a 1000w generator and only weighs 25kg. I have a workshop full of welders and was hoping this little unit would allow me to do some onsite repairs and the odd bit of fencing. My generator is only a 6kva unit so not big enough to run a 140amp inverter welder so I thought this little unit would fit the bill. It will be ok for welding anything 4.8mm & over but a most of the time I will be using 2.5 rods on 2-3mm pipe etc. I want 70-80 not 130. Does anyone know if a potentiometer can be fitted or some other method of reducing current. The supplier is no help, only order takers with no technical advice. Appreciate any help

Uh. Rossi.
You could probably use a resistive load bank, usually used for simulating a load on a welder for testing purposes... but I have no experience with this.
Plus one would probs cost more than the welder/generator.
Chuck her up on gumtree for a nibble and invest in something better / suited.

Can be done, but the cost of material and labour to do so will exceed the cost of the machine. A rheostat to deal with that sort of power dissipation will be an even more costly exercise.
Like Commander said, move it along and buy something fit for purpose.
