I'm sure it'd be fine for the lighter stuff and if you say 'tis well built then it may not be so bad as a DIY machine. I just can't believe they can get away with advertising a machine as 200amps if it only has a 13% D/C at that level. Is there no standard saying that the max power should be quoted at 60% D/C or something along those lines? I guess there isn't. It'd make things a lot clearer.
