Welding current
Pulse MIG/MAG only has “synergic” mode, while “separate” mode is unavailable. Under “synergic”, voltage can
be adjusted with a focus on synergic voltage±9.9V.

Parameters setting
Under standard MIG/MAG, adjustable parameters include: pre-flow time; welding specification of initial segment:
welding current (or wire feed speed/board thickness), welding voltage, arc force (inductance); transition time from initial
to process; welding specification of process: welding current (or wire feed speed/board thickness), welding voltage, arc
force (inductance); transition time from process to crater; welding specification of crater segment: welding current (or
wire feed speed/board thickness), welding voltage, arc force (inductance); post-flow time.
Arc force: arc force range is -10~+10; 0 is the standard central value; adjust to the positive direction and arc will be
harder and weld bead will be narrower; if adjust to the negative direction, arc will be softer and weld bead will be
broadened; arc force can be set respectively at welding process, initial and crater.

Note: Different welding wire has different welding current range; with different welding wire, wire feed
speed differs even under the same current
