PROTECTIVE GAS
Both argon and helium work when welding aluminum. Argon is preferred, due to its lower cost and consump- tion rate. This gas also tends to stabilize the arc, thus making it easy to operate. For some applications, how- ever, the use of helium, or

WARNING
ELECTRIC SHOCK can kill.
•Have an electrician install and service this equipment.
•Turn the input power off at the fuse box, dis- connect or unplug supply lines and allow machine to sit for five minutes minimum to allow the power capacitors to discharge before working inside this equipment.
•Do not touch electrically hot parts.
Connect the shielding gas – typically argon – using a appropriate regulator. Connect the foot amptrol, torch and work lead to the power source.
With the work cable connected to a properly grounded work piece, turn the power source on.
To change the AC Frequency, press and hold the Parameter button for 3 seconds. The AC Frequency is now selected and can be varied by the Output Control. The frequency is displayed on the digital meter. After about 5 seconds, the power source will switch back to the welding mode ready to weld with the new selected AC Frequency.
To change the AC Balance, press and hold the Parameter button for 3 seconds, AC Frequency is selected, press the Parameter button again and AC Balance is selected. Adjust the Output Control for the desired AC Balance. After about 5 seconds, the power source will switch back to the welding mode ready to weld with the new selected AC Balance.
To change the Post Flow time, repeatedly push the Parameter button until the Post Flow indicator light is on. Adjust the Output control to the desired Post Flow time as indicated on digital display.
