Just about to buy myself a welder for mainly jobs that need doing when building motorcycle specials, i used to do a fair bit of welding when i was a maintenance engineer but have never needed to since, but i have seen two welders locally and they may go fairly cheap but i need to know what they are worth and are they any good, one is a Omega 210 ac/dc tig and the other is a Kempi 1701, they are like new and seem to be nice bits of kit any ideas?
