Optional Access Operation Description - Yeswelder CT2050 Operator's Manual

BASIC KNOWLEDGE OF WELDING
The workpiece is not cut fully. This may be caused by:
The cutting current is too low.
The cutting speed is too high.
The electrode and nozzle of the torch are burned. The workpiece is too thick.
Molten slag drops from the bottom of workpiece. This may be caused by:
The cutting speed is too low.
The electrode and nozzle of the torch are burned.
The cutting current is too high.
Replacement of Electrode and Nozzle
When the phenomena below occur, the electrode and nozzle should be replaced. Otherwise, there will be strong arc in the nozzle,
which will break down the electrode and the nozzle, or even burn the torch. Nozzles of different models are different, so ensure the
nozzle is of the same model when replacing it.
1) Electrode wear＞1.5mm
2) Distortion of the nozzle
3) Cutting speed declining, arc with green flame
4) Difficult in arc ignition
5) Irregular cut

OPTIONAL ACCESS OPERATION DESCRIPTION

Pedal Remoter Operation
Pedal remoter control internal structure is composed by inching switch and sliding potentiometer (10K), as shown in below Fig 27.
The pedal controlling function is only used while it's under TIG mode.
Connect the pedal remoter to the welder front panel pedal controller interface through dedicated cable. See Fig 28
Ÿ
Switch to remote mode by the torch mode select
Ÿ
Tread the pedal control and start arc ignition. Non-contact arc ignition is the mostly applied method. Welding current will be control
Ÿ
by pedal remoter after successful arc ignition. Max output current is the preset current.
Note: Pedal remote controller is optional. Please clarify your needs before placing orders.
