I'm watching a couple of Ceborea/SnapOn pocket migs on ebay as I've realized in need a mig for some motorcycle fab work. Are they any good? And what is the maximum output for them? I looks like 100 odd amps on one of the spec plates but I'm not sure. This is the item no for one of them 172463105532, the other is much closer to me but has wire feed problems, are they known to have trouble with the wire feed? I've endured a SIP before so don't want to buy another poorly designed machine!
