The PRO 100 is suitable for .035" aluminum wire and
.030" stainless wire. Refer to Table B.1 for recom- mended procedure settings. (Requires
CAUTION
It is important when changing between welding with steel wire and aluminum to exchange feeding components due to the lubricant applied to steel wire. Failure to do so may result in contaminated welds when welding aluminum.

CHANGING MACHINE OVER TO FEED OTHER WIRE SIZES
The PRO 100 is shipped from the factory ready to feed 0.035” (0,9 mm) diameter cored wire. To operate the PRO 100 with other sizes and types of wire, it maybe necessary to change the contact tip and drive roll orientation. Refer to the MAINTENANCE section, for component configuration and replacement proce- dures.
WELDING WITH GMAW (MIG)
Shielding Gas
When using the GMAW process, obtain and install the
1.For CO2, open the cylinder very slowly. For argon- mixed gas, open cylinder valve slowly a fraction of a turn. When the cylinder pressure gauge pointer stops moving, open the valve fully.
2.If using a regulator with an adjustable flow meter, close the gun trigger and adjust the flow to give 15
–20 cubic ft per hour (CFH) (7 – 10 I/min) [use 20
–25 CFH (10 – 12 I/min) when welding out of
position or in a drafty location for CO2]. For argon mixed gas, trigger to release gas pressure, and turn off the adjust the flow to give 25 – 30 CFH (12 – 14 I/min).
3.Keep the cylinder valve closed, except when using the PRO 100. When finished welding:
a) Close the cylinder valve to stop gas flow.
b) Depress the gun trigger briefly to release the pressure in the gas hose.
c) Turn off the PRO 100.
OVERLOAD PROTECTION
Output Overload
The PRO 100 is equipped with a circuit breaker and a thermostat which protects the machine from damage if maximum output is exceeded. The circuit breaker but- ton will extend out when tripped. The circuit breaker must be manually reset.
Thermal Protection
The PRO 100 has a rated output duty cycle of 20%. If the duty cycle is exceeded, a thermal protector will shut off the output until the machine cools to a reason- able operating temperature. This is an automatic func- tion of the PRO 100 and does not require user inter- vention. The fan continues to run during cooling.
