SETUP AND OPERATION
POWER SOURCE
Use only constant voltage type power sources with this circle welder machine. If using a multiple process
power source, be sure that it is set for constant voltage output as per the instructions in the manual for
the power source. Set the power source polarity switch or properly connect the electrodes and work leads
for the correct electrode polarity.
FIXTURING
All circle welders have to be fixtured in some manner from the top of the shaft. This may be achieved in
one of the following: column & boom, manipulator or carriage & monorail.
GUNS AND CABLES
All circle welders come equipped with a gun and cable assembly. It is our recommendation that at least
once a week the liner be taken out of the cable and soaked overnight in a solvent solution. To keep the
wire moving it is also recommended that a felt clip be saturated with a product like Ferro Slick and feed
through the incoming tube of the wire feeder at least once a day.
