MIG Welding aluminium is slightly different to MIG welding mild steel as aluminium has different welding properties. When welding aluminium it is important that the following issues are addressed with your MIG welder.
After making all the necessary changes to your MIG welder set up you are ready to MIG weld that aluminium welding project. Remember to keep in mind Aluminium is a great conductor of heat and soaks up a lot of your MIG machines capacity in dispersed heat and you will only get approximately half the relative penetration of weld compared to the same current(output)settings as those for steel
remember aluminium when hot does not look hot and always be cautious when handling freshly welded aluminium as it can look deceptively cold
