Mobile welding machines

(OP)
Hello everbody,
I need some fundamental information about mobile welding machines. They run from small rechargable battery and are capable of doing small welding jobs requiring 4-5 electrodes without using main power.  

Thanks in advance

RE: Mobile welding machines

welders that run off batteries? sounds interesting. i use a miller maxstar 200sd (inverter TIG). FWIW, it only weighs about 35lbs and is extremely portable.

RE: Mobile welding machines

The first stick welding was done with banks of batteries.  They also sell kits so you can do it with your vehicle.  It should work as it has been done before, but I wouldn't know what kind of arc characteristics they have.  It could be much more difficult than a regular welding machine.

RE: Mobile welding machines

The only portable welding "machines" I am aware of require a source of constant power, i.e. generator. If a welder operates on stored power,battery,the arc will become increasingly unstable as the stored power is diminished.
By "4-5 electrodes", I assume you mean SMAW (stick)welding, consumable electrodes, which requires a dependable,constant potential power source to produce a sound weld.
