Tweco 210 MIG Thermal Arc Fabricator - Manual (Page 40)

FABRICATOR 210
OPERATION 4-2 Manual No. 0-4855
ON / OFF Power Switch
The indicator light is provided to indicate when the Fabricator 210 is connected to the Input Power Supply Voltage.
With the switch in the Standby position, the auxiliary power and the fan are turned off and the switch is illuminated.
WARNING
When the light is lit, the machine is connected to the Mains supply voltage and the internal electrical
components are at Mains voltage potential.
Thermal Overload
The critical component for thermal protection are the rectifier stack and the transformer, which are fitted with
thermal overload cut out devices. If the overload is activated then the machine should be left to cool for approximately
15 minutes before resuming welding. If the Power Source is operated within its duty cycle, the thermal overload
will not activate. Refer to section 2.09 for an explanation of duty cycle and section 2.10 for the power supply
specifications.
Wirespeed Control
The Wirespeed Control knob controls the welding current via the electrode wire feed rate, i.e. the speed of the wire
feed motor. The wire speed is variable from 80 to 800IPM (2-20 m/min).
Coarse Voltage Switch Selector
The Coarse Voltage Switch Selector sets the voltage level to the welding terminals as it switches from 1 to 4.
Fine Voltage Switch Selector
The Fine Voltage Switch Selector increases the voltage (in smaller increments than the Coarse switch) as it switches
from 1 to 4.
CAUTION
The Coarse & Fine Voltage Switch Selectors MUST NOT BE SWITCHED during the welding process.
