Can I Modify Lower Amperage

[rodbox5]

I have a MIG Welder which currently has an output range of 40 - 160 Amps over 4 switch settings

For thinner metal work, I would really like to be able to have a lower setting of around 25 - 30 Amps.

Is it possible/viable to have a technician modify the welder's components to achieve output at this level?

Not unless they are willing to add windings to the transformer.

I was thinking more along the lines of upgrading the whole transformer - there are quite a few good salvaged units available here.

The question is how labour intensive and technically difficult is it to fit them?

It would probably be cheaper to fix the "salvaged units" you refer to (I don't see any )

Here as in Perth Western Australia.

The industrial recyclers strip them down and sell the spare parts.
