Longer time will cause waste of gas; shorter time will cause air hole during crater filler period
- P05 Initial period
Special 4-step mode and set the percentage between initial period and preset parameters. When adjust the initial period,
press F2 and then adjust dial (1), make correction of the arc length of the initial period. Press F2 again to exit.
- P06 Crater filler period
4-sept or special 4-step mode, set the percentage between crater filler period and preset parameters. When adjust the
crater filler, press F2 and then adjust dial (1), make correction of arc length of the crater filler. Press F2 again to exit.
- P07 Transitional period
During the special 4-step mode, the time cost from starting current to normal welding current and then to post current
- P08 Spot welding time
Choose spot welding process and set the welding time
- P09 Digital/Analog signal selection
In ON mode, welding parameters can be adjusted by welding machine control panel, digital wire feeder control panel; in
OFF mode, welding parameters can be adjusted by analog controller.
- P10 Water cooling selection
OFF: gas cooled mode, choose gas cooled torch, no water shortage protection;
ON: water cooled mode, choose water cooled torch, there is water shortage protection.
- P16 Fan-on demand cooling time
Set the time that fan continues to work after power source stops welding.
- P17 Arc start time
On special 2-step mode, time for start period. When choose at number, it is time for start period, when reach to this time,
will turn to welding standard; when choose at OFF, the function closes.
- P18 Arc stop time
On special 2-step mode, time for crater filler time. When choose at number, it is time for crater filler, when reach to this
time, will turn to stop welding standard; when choose at OFF, the function closes.
- P19 Separate adjustment mode
In OFF mode, current and voltage is synergic adjusted; in ON mode, current and voltage is separately adjusted.
- P22 Pulse current when start arc
Too small will cause wire touches with work piece, and arc start fails. Too large will cause large energy when start arc, and
arc has defect.
- P23 Pulse time when start arc
Too short will cause difficult to start arc; too long will cause large energy when start arc, and arc has defect.
- P24 Short circuit rise rate
The higher the short circuit current rise rate is, the harder the arc is, and the large spatter is; otherwise, arc will be softer,
spatter will be lesser. Too small will cause unstable welding.
- P25 Short circuit rise knee point
The higher the short circuit rise knee point is, the harder the arc is; otherwise, the softer the arc is. Recommend to use
factory setting parameter value.
- P26 Arcing peak value
The higher the arcing peak value is, the longer the arc length is, the stronger the directivity is; otherwise the shorter the arc
is, the weaker the arc directivity is. Too low value of this parameter will cause unstable welding.
- P27 Arcing peak time
The longer the arcing peak time is, then the larger arc energy is, the larger welding heat affected zone is; otherwise, the
smaller arc energy is, the smaller welding heat affected zone is. Too low value of this parameter will cause deformed weld.
- P30 Inch wire feeding speed
Set manual wire feeding speed.
- P31 Molten drop transition time 1
This parameter is used together with P32, the longer the time is, the larger arc energy is, the longer droplet transfer time is,
the softer arc is; otherwise, the smaller arc energy is, the shorter droplet transfer time is, the harder arc is. Recommend to
use factory setting parameter value.
- P32 Molten drop transition time 2
This parameter is used together with P31, the longer the time is, the larger arc energy is, the longer droplet transfer time is,
