OPERATION - PULSE 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 Pulse Welding Mode: (Continued)
Pulse Welding Control:
When in Pulse mode welding amperage (80A as shown right) control
becomes the default adjustment setting (as shown right, and the upper
rotary encoder and push button which when pressed will scroll the
operator through amperage control, wire feed speed and material
thickness.
Pulse mode allows the operator to rotate the lower left control dial
clockwise to increases not only the welding current but also the background wire feed speed and material
thickness settings and rotating the dial anticlockwise will decrease the wire feed speed ultimately
reducing welding current.
In the example shown left, when you increase current from 80A to 100A,
you will note the following settings also increases via the screen:
•
Wire feed speed increased from:
•
Material thickness increased from:
•
Welding voltage increased from:
Arc Length Control:
Arc length control gives the operator the ability to have increased or
reduced 'stick out' in synergic mode which enables further fine tuning or
trimming by adjusting arc length and voltage in smaller increments.
This allows the operator to trim and shape the weld bead profile.
You can increase or decrease arc length voltage by up to -20 to +20 % of
the programmed value. "0" is the mid point and when accessed will be
shown in the voltage value.
Turning the lower right control dial anti-clockwise to shorten the arc
length and rotating clockwise to lengthen the arc length and you can see
in the image right that increasing the trim to 7% has also increased the
welding voltage from 14.5v to 15.8v which is also noted via the slide bar
in-between the arc length control (trim) readings.
Trigger Mode:
Press the 2T/4T/Spot icon to select the 2T
torch trigger mode. On selecting 2T, only
the 2T icon will be shown as circled red
right.
See page 86 for details on MIG torch trigger
function.
