Description
The Tweco Foot Control is a foot operated switch and potentiometer which starts and stops the welding process and controls welding
current through operation of the foot pedal. Refer to list below for compatible Tweco power sources.
Installation
Attach the 8-pin connector on the end of the cable to the 8-pin receptacle on the front of the welding machine. To complete the con-
nection, align the keyway, insert the plug, and rotate the threaded collar fully clockwise.
Foot Control Operation
The foot control listed above Part Number W4013200 foot control will allow you to adjust the maximum output preset amperage. Other
8 pin remote's used with some of our other welders will function as below.
Press the foot pedal to start the machine output functions. The foot control potentiometer controls the welding current up to the level
set on the welding power source. Note that the maximum current must be set on the power source by the operator
prior
to the foot
control being connected. With the foot control connected, the power source will only display minimum preview Amps until the foot con-
trol is depressed then it displays actual welding current when welding. Pressing the pedal to increases the welding current; letting up
on the pedal decreases the welding current. Releasing the pedal completely extinguishes the arc and initiates the post-flow shielding
gas timer (where fitted).
Note that some power sources may require the remote/local switch set to remote, the maximum setting of the power source will be de-
termined by the respective front panel control, irrespective of the remote control device setting. As an example, if the output current on
the power source front panel is set to 50% of the available current and the remote control device is set to 100% output or maximum,
the maximum achievable output from the unit will be 50%. Should 100% output be required, the respective front panel control must be
set to 100% or maximum, in which case the remote device will then be able to control between 1-100% output.
NOTE!
Note 1: Some power sources other than specified as above may not function with the foot control.
Note 2: The foot control will only work correctly when power source trigger mode 2T (Normal) is selected.
