How to MIG Weld a Lower Unit
Metal inert gas, or MIG, welding guns join two pieces of metal together, using a point-and-click method. MIG welding guns can reach temperatures of up to 10.000 degrees F, making them effective tools to weld metal. When you are welding a lower unit, you need to check on the materials of the upper units. Only MIG welds the lower unit if the upper units are made of non-flammable materials. Does this Spark an idea?
