How to assemble / Install Millermatic 190

Lift the Millermatic 190 using the handles and locate it near the correct power supply.

Special installation required for areas where gasoline or volatile liquids are present. For further instructions, refer to the manual.

Read the manual carefully for connecting phase input power. Failure to meet given standards may damage the machine.

When assembling the equipment, make sure you tighten connection hardware with proper tools. A loose electrical connection will cause poor weld performance and excessive heating of the work clamp.

How to Use Millermatic 190

Adjust the voltage and wire speed by turning the controls clockwise. The over-temperature light will turn on in case of overheating.

Adjust the Voltage/Material control to appropriate settings and turn the power switch on. If the gun is on for more than three minutes without initiating the arc, it will enter jog mode.

To exit jog mode, release the gun trigger. The owner’s manual comes with a weld parameter chart. Refer to this chart to know which settings will suit you.

Is a spool gun needed to weld aluminum?

To weld aluminum successfully, you need a steady arc. A spool gun helps give you a stable, reliable feed. However, experienced welders can do it without one.

What polarity is needed to weld aluminum?

MIG welding aluminum requires reverse polarity. This can be called DCEP or direct current electrode positive.

What gas should I use for MIG welding aluminum?

100% Argon gives the best performance but you can also use 20% Carbon Dioxide or 50% Helium for MIG welding.
