10. OPERATION (continued)
CAUTION
For electrode stick, follow the instruction below.
٨
Keep the electrode stick in a place with low humidity.
٨
Dry the electrode stick sufficiently before using.
٨
When the gas burner is used for pre-heating or removing moisture of the base metal, be
sure to heat to 100˚C or above.
٨
Slag and fume generated when tack welding will cause wetting the part of base metal to
be welded. Remove slag and fume immediately after tack welding.
٨
When welding is performed outdoors and wind velocity exceeds 10ft/sec, use a wind
shield.
10.2
DC STICK welding
10.2.1
DC STICK welding
Set the welding process to DC STICK welding ( )
with the WELDING METHOD key [1].
The welding current setting mode is automatically selected and setting value is indicated on
the left digital display with the unit indicator LED for amperage “A” turned ON.
When switched to DC STICK welding, or when turn on the switch with DC STICK welding is
selected, no-load voltage is not provided for approx. 5 sec. for safety. 5 sec. later, the voltage
is automatically provided.
10.2.2
Welding current setting
The welding current may be set with the parameter adjusting knob [4] in the range specified
in the table shown below:
Current range is 10A-250A.
10.2.3 Internal function setting
The function listed below may be adjusted with Function selection key [10]. See Subsection
10.1.17 for internal function setting.
(1) Hazard reducing function: Function No. 8
This is a safety function that reduces risks of an electric shock by limiting no-load voltage
of welder to lower level at any time except welding period.
It is therefore recommended to utilize this function when the machine is used at high site or
in confined environment.
The factory setting of this function is [OFF]. To activate this function, set Function No. 8 to
[ON].
10.2.4
Analog remote control (K5416T)
This machine automatically recognizes the analog remote control. When the analog remote
control is connected to the machine, the only remote control is effective and the parameters
“welding current (base current)” and/or “pulse current” selected on the front panel may not be
adjusted by the parameter adjusting knob [4] on the front panel. They must be adjusted on
the analog remote control that is connected to the machine. Those set values may be
monitored on the digital display on the front panel.
When take off the remote control, setting figure disappear.
