I know there's a few people on the board using these.
As a new owner (Woohoo!!!) I was wondering...
Has anyone done a chart for theirs with starting point wirefeed/power settings for various materials?
Might save me (and others) reinventin the wheel.

Mike, the best way to work out your settings is to "clock" your machine.
Look on your wire feed dial as a clock face. I usually start at 8 or 9 O'clock on the dial and do a trial weld on scrap metal. Start at a low power setting and increase till it's welding at its optimum for a 8 or 9 O'clock setting, Do the same for 10 O'clock, 11 O'clock etc, etc, all the time writing the O'clock settings and power settings down. ( I usually write mine in Texta on the side of the welder)
Once you've done this it's simple to go to the best power setting for any O'clock position on the wire feed dial. Sometimes the O'clock settings you wish to use may be 1/2 way through, eg: 10.30 O'clock. If this is the case try the power settings of 10 and 11 O'clock and use whichever gives the best results.
Regards Andrew.

Sorry, forgot to say. You need to clock your machine if you change wire size and any change in type of material to be welded.
eg: you need 3 different clocks to do steel, aluminium, stainless steel.

Thanks Andrew, good advice
the procraft 240 has digitally set wire speed (as a percent of max) but the same principal should apply.
I had thought that since a few people on the board had these welders they may have done it already.
If anyone is interested I'l post mine once I've done as you suggested.
