lower cost. A mixed gas consisting of 75 to 80% Argon and 20 to 25% CO2 is recommended for weld- ing on heavier gauge [12 gauge (2,5 mm) for exam- ple] steel.

The PRO 100 is suitable for .035" aluminum wire and

.030" stainless wire. Refer to Table B.1 for recom- mended procedure settings. (Requires K610-1 MIG Conversion Kit and K664-1 Aluminum - Stainless Feeding Kit.)

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 is necessary to change the contact tip, drive roll and cable liner configuration. Refer to the MAINTENANCE section, for component configuration and replacement procedures.

WELDING WITH GMAW (MIG)

Shielding Gas

When using the GMAW process, obtain and install the K610-1 MIG Conversion Kit and a cylinder of carbon dioxide (CO2) or argon-carbon dioxide mixed shield- ing gas. Refer to the ACCESSORIES section for more information about installing the K610-1 Kit for use with the PRO 100. Also see the MAINTENANCE section for proper contact tip, nozzle liner and drive roll config- uration.

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.

Electronic Wire Drive Motor Protection

The PRO 100 has built-in protection for wire drive motor overload.
