CLEANING TIP AND GAS NOZZLE

 

 

Keep the contact tip and nozzle clean to avoid arc bridging between them. Bridging can result in a short- ed nozzle, poor welds and an overheated gun. Hint: Anti-stick spray or gel, available from a welding suppli- er, may reduce buildup and aid in spatter removal.

CHANGING MACHINE OVER TO FEED

OTHER WIRE SIZES

The machine is shipped from the factory ready to feed 0.035” (0.9 mm) diameter wire. To operate the machine with other sizes of wire, it is necessary to change the contact tip and change the drive roll to other sizes. Refer to Changing the Contact Tip and Changing the Drive Roll in the MAINTENANCE sec- tion for specific information on these procedures.

OVERLOAD PROTECTION

THERMAL PROTECTION

The machine has a maximum 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 normal operating temperature. This is an automatic function of the machine and does not require user intervention.
