The following summary provides a brief overview of the front switch panel (see
Fig.4
). If you have any additional questions relating
to the equipment please contact your nearest Jefferson Dealer before using the equipment.
6.1. “ON/OFF” switch
When the switch is in the “OFF” position it means power has been shut off to the welder, when the switch is in the ”ON”
position it means power is supplied to the main transformer and control circuit.
6.2. “MIN/MAX” switch
The “MIN/MAX” and "1/2" switches are on the front panel of the machine. Each have two settings. You can choose different
setting combinations of the two switches according to the metal thickness.
6.3. Wire speed control knob
Used to control the wire speed: turn clockwise to increase the wire speed or counter-clockwise to decrease the wire
speed. The numbers (0-10) around the knob show the wire feed speed. The rated wire feed speed for this equipment is
1.8m/min ~ 11.4m/min.
6.4. Overload light
If you are welding with a large current for a long time and exceed the duty cycle, the overload lamp will light (yellow), and
the welder will automatically shut down until it cools down. If this happens, you must stop welding and wait
approximately
5 minutes,
before the unit will reset and allow you to continue welding.
