The screen below shows all the advanced MIG manual options.
Use the middle selector to cycle though the available modes, selected mode is highlighted in red.
Use the left knob to adjust value.
For most common MIG welding we suggest setting all to zero apart from
Burnback 0.2s and post flow 0.2s.
Pre-flow gas - adjusts gas time on before weld power and wire speed activated.
Start / End - Power for start / finish of weld
Up-slope - time from start power to main power.
Inductance - 0 = softer arc with less splatter, 100 = stronger/harsher arc, more splatter.
Spot - Sets length of spot weld
Stitch - If above zero, the spot weld will be repeated after this delay.
Burnback - Time in seconds that power continues after wire stops at trigger release - This stops wire stick-
ing to workpiece. Recommended general setting is 0.2s
Down-slope - time from main power to end power setting in seconds.
Once you have set the above you can go back to main MIG screen by turning middle knob to highlight the
following icon in RED, then pressing in middle knob. There you can adjust wire speed and voltage.
