Lightweight Aluminum DesignAluminum Air Compressor | Generator | Welder | Battery Booster | Battery Charger

The Air N Arc® 250-L features an aluminum reciprocating air end, base, and sheet metal to reduce the weight of a standard steel skid mount system by 30%. The Air N Arc 250-L still offers all the advantages you expect from an ALL-IN-ONE Power System® including five forms of power in a single machine, increased availability of valuable bed space, reduced spending costs on purchasing multiple machines, and reduced truck idle time by turning off the truck. Be ready any time, by having all your necessary power sources on board, all of the time!
