Hi Folks
Please allow me to introduce myself. I'm Rob and I'm the world's worst welder. So for a bit of fun I bolted an old mig torch to a cnc milling machine to see what results I'd get as the table zig-zagged it's way forward.
The results are better than expected and I think it will enable ourselves to do more in-house work during these difficult times.
I have a few questions:
1) Consider welding, say, a 3" dia bar to a piece of flat and weld is required down the length of the bar. The shrouds/nozzles I've seen (tapered and conical MB25?'s) don't allow the electrode tip to get close enough 'under' to the root of the 'fillet' weld. Are there any special shrouds available to help here?
2) If I have to somehow make my own shrouds for the this problem will bare copper give problems compared to chrome plated shrouds?
3) I haven't been able to determine the welding current that relates to the wire-feed speeds. Will a clamp-on ammeter give sensible, comparible results?
4) The set-up I have is a bit restrictive in that the welding is in only one plane but with the correct jigs it is quite versatile. I'm not ISO9000 registered. Do you think there's any chance of picking up some sub-contract work for small parts requiring some simple, neat, bench welding at a fraction of the price of that done by Panasonics / Fanucs etc.? Anyone out there wanting to act as Principal on this?
Thanks
