Despite being 20+ years old this Kemppi RA 450 water cooled MIG welding machine is in incredible condition. The water pumps which are located internally to save space have been checked over thoroughly and flushed out with fresh de-ionised water, are as powerful as a fireman's hose and silent as a mouse.
We bought x37 of these beauties from an auction and have made some of them air cooled packages for lower amperage welding as well. We have checked and serviced them all, having blown them out and found the insides to be immaculate and in perfect condition.
The RA 450 is known for having a smooth arc characteristic due to how Kemppi made the diode bank and rectifier, and they are such a joy to weld with. We used them in our shop here at Spectrum when in-housing manufacturing our welding rotators and they weld just as good as our brand new welder inverters that we sell, and that is no exaggeration. Obviously they are slightly bigger and bulkier that the new technology welder inverters that only weigh 40kg but the RA 450 is built to last and we love them.
We have made them available to hire or to buy and fitted brand new Rival Wire x4 drive roll wire feeders with them which are very reliable.
