cars that accompanied the product look more attractive spg, spg this could explain the benefits of the car, this car was designed  with mig welding. She explained The   primary advantage of MIG welding is that it allows metal to be welded   much quicker than traditional welding "stick welding" techniques. This   makes it ideal for welding softer metals such as aluminum. When MIG   welding was first developed, the cost of the inert gas (i.e., argon)   made the process too expensive for welding steel. However, over the   years, the MIG welding process has evolved and semi inert gases such as   carbon dioxide can now be used to provide the shielding function which   makes MIG welding cost effective for welding steel.
