INSTALLATION, OPERATION AND SETUP 3-18 Manual 0-5241
Description
The CIGWELD 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
Cigweld 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 connection, align the keyway, insert the plug, and rotate the threaded collar fully clockwise.
Foot Control Operation
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, although this can be adjusted while
you are welding.
With the foot control connected, the power source will only display minimum preview Amps until the foot
control 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 determined 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: The foot control will only work correctly when power source trigger mode 2T (Normal) is selected.
