OPERATION - MIG
Before starting any welding activity ensure that you have suitable eye protection and
protective clothing. Also take the necessary steps to protect any persons within the welding
area.
MIG/MAG standard welding mode
When in standard MIG mode, you can now adjust various MIG parameters such as pre & post gas flow,
burnback voltage and initial slow wire feed speed and these which are adjusted via the welding engineer
mode (WEM) function that allows the users to adjust a number of background default parameters or
functions.
To access WEM, press and hold the top adjustment knob (‘ K ’ as per previous page) for 5 seconds, after
pressing and holding this knob for 2s, the machine will show a count down from 3 seconds, at the end
of the countdown, the top display window will show the parameter number "F01" with the bottom
parameter displaying the value corresponding to that
‘ F ’ number.
By rotating the top parameter adjustment dial will allow you to select the required parameter number to
set the back
- end parameter default value or function (see pages 25 onwards for further details).
•
MIG pre - gas selection and adjusting:
To select pre flow gas time setting, rotate the top adjustment dial until F03 is displayed, by rotating
The bottom dial, you can then adjust the pre flow time shown in the bottom display window.
The pre flow adjustment range is 0 ~ 2 seconds and the factory setting is 0.1 seconds.
•
MIG post - gas selection and adjustment:
To select post flow gas time setting, rotate the top adjustment dial until F04 is displayed, by rotating
the bottom dial, you can then adjust the pre flow time shown in the bottom display window.
The pre flow adjustment range is 0 ~ 5 seconds and the factory setting is 0.5 seconds.
•
Burnback voltage adjustment:
To select and adjust downslope time, rotate the top adjustment dial until F06 is displayed. Then by
rotating the bottom dial you can then adjust the burnback voltage is shown in the bottom
display window. The burnback voltage range is 10 ~ 20 volts and the factory setting is 13 seconds.
•
Initial wire feed speed adjustment (also known as creep speed):
To select and adjust the initial ‘ slow ’ wire feed speed, rotate the top adjustment dial until F08 is
displayed. Then by rotating the bottom dial you can then turn on and adjust the initial feed rate
speed that is shown in the bottom display window.
The initial wire feed speed settings are as follows:
"0" indicates that the slow wire feed function is disabled. "1", "2" or "3" indicate that the slow wire
feed speed is 1/3, 1/2 or 2/3 of the set wire feed speed respectively. The factory setting is 1.
Once any adjustments are carried out, pressing the green button exits the welding engineers mode and
saves your settings.
MIG - Gasless
The operation method is the same as the above MIG operation except there no shielding gas is used and
the output polarity for the MIG torch and the work return lead is reversed (see page 30).
