Mig Welding Aluminum is just more difficult than mig welding steel.
Why? Because everything that can go wrong on Steel, is just magnified when you mig weld aluminum. Even something as simple as the argon flow rate makes a big difference. A slight tweak of the wire feed speed changes things up big time. Even a [...]

WHAT IS STAINLESS STEEL?
Austenitic, Martensenitic and Ferritic Stainless Steels Austenitic Stainless Steels are the ones we are most familiar with. These chrome nickel steels, in contrast to lower cost stainless have more alloys and are “non magnetic” (Exception, types 310 – 330) Austenitic Facts: Austenitic grades typically contain a minimum of 18% chrome – [...]
IDLE ROLL PRESSURE SETTING
The idle roll pressure is set at the factory backed out two turns from full pressure. This is an approximate setting. For small wire sizes and aluminum wire, the optimum idle roll pressure varies with type of wire, surface condition, lubrication and hardness. The optimum idle roll setting can be determined as follows:
1. Press end of gun against a solid object that is electrically isolated from the welder output. Press the gun trigger for several seconds.
2. If the wire “bird nests,” jams or breaks at the drive roll, the idle roll pressure is too great. Back the pressure setting out 1⁄2 turn, run new wire through gun, and repeat above steps.
3. If the only result is drive roll slippage, shut off the power source, then loosen the gun cable clamping screw in the gearbox conductor block and pull the gun cable forward about six inches. There should be a slight waviness in the exposed wire. If there is no waviness, the pressure is too low. Increase the pressure setting 1⁄4 turn, lock the guncable in place and repeat the above steps.
