Who here is using an inverter welding machine as a mobile unit? Besides using a generator,how else do you power the inverter? Do you use customer supplied power,if so how do they feel about you doing that? I ask because I am thinking of the best cost solution to me to be able to offer mobile tig welding of aluminum and s/s. Having a toyota p/u and wanting to keep initial cost low, is it even feasible to think that I can use customer supplied power?
