CRATER FILL current and voltage control knob
These are for the crater current and crater voltage control. Set them to the optimum crater fill
conditions.
PULSE ARC CONTROL knob
Normally, use in the “
” position (standard). It adjusts the pulse arc stability. If it is adjusted to
the “RIGID” side for low current operation or the “SOFT” for high current operation, the best
result will be obtained. In case of using extended welding cable (if total length is more than 60ft.
(20mm)), adjust to the “RIGID” side to obtain the best result in normal operation.
Cooling method of torch (
“
”
Set to proper position according to torch type.
Gas switch (
“
”
Set it in “GAS CHECK” position to check gas.
Set it in “WELD” position to weld.
Even when welding with the gas switch set to “GAS CHECK” side, the gas solenoid valve is still
controlled according to the welding procedure. This ensures that even if switch is left in “GAS
CHECK” side, no wasteful gas flows when welding is stopped.
After welding with the gas switch set to “GAS CHECK” side and then performing gas check
again, return the gas switch to “WELD” side and then set to “GAS CHECK” side.
CONSTANT PENETRATION switch
Set to “
” position when using penetration control.
The penetration control functions only during main welding. Note that even if setting the switch
for penetration control to “
”, the penetration control does not function during crater fill.
CURR.VOLT. CONTROL switch
Select a method of curr. / volt. setting.
Refer to “5.2 Remote control box”.
PROGRAM switch for changing welding process / wire size
According to welding process / wire size used, select the appropriate number to press [
] or
[
] button. The assignment table for the number and the welding process / wire size is shown in
table 5.1 of next page. (Do not set a number other than those of in table 5.1).
CRATER FILL switch
Crater fill functin will work in “
(W/O PULSE)” or “
(W/PULSE)” position.
Power lamp
This lamp comes on when the input power to the welding power source is allowable whether
power switch is ON or OFF.
WARNING lamp and temperature lamp (“ ”)
When these lamps come on, output stops automatically.
Refer to “11.APPLIED FUNCTION” to reset the system.
Power switch
When turned on this switch, the fan starts rotating and the machine becomes ready to use.
WAVE PULSE knob (option)
When wave pulse welding (option), adjust the knob according to welding procedure to obtain
favorable bead appearance.
