KNOB FUNCTIONS
Wire Speed & MMA & TIG Amperage:
In MMA mode you can adjust the output amperage. In MIG mode it adjusts
the wire speed and proportionately affects the amperage. The increase in wire speed determines the amount of weld
penetration. Too high of a wire speed will result in a burn through. It is important to correlate the welding voltage and
the wire speed to achieve the desired result. It is highly recommended that you practice on a scrap piece of metal to
determine what wire speed and voltage combination is suitable for the metal to be welded. The chart below is a good
starting point of voltage and wire speed settings that can be used in relation to the welding wire diameter.
MIG Voltage:
Adjustment of welding voltage determines the width and height of the bead. Turning the knob clockwise
increases the welding voltage. There is a correlation between the welding voltage and the arc length. A short arc
length will decrease the voltage which will result in a narrow, "ropey" bead. A longer arc length (obtained by increasing
the voltage) will produce a more flat and wider bead. An excessive arc length will yield an incredibly flat bead or an
undercutting of the weld metal. It is highly recommended that you practice on a scrap piece of metal to determine what
voltage is suitable for the metal to be welded.
Arc Force:
Adjustment of arc force is used to control the welding characteristics when MMA/Stick welding.
Adjustment of arc force is ideal when using a cellulose based rod as it can help achieve good penetration and reduce
arc sticking. It also helps to keep the weld pool fluid in situations where the voltage would normally drop resulting in an
extinguished arc. An example of this, would be welding in tight corners or in applications requiring a shorter arc length.
Decreasing the arc force setting will decrease penetration and spatter, which is ideally used for thinner material.
Increasing the arc force setting will increase penetration and spatter, which is ideally used for thicker material.
Spool Gun
: To install the spool gun you must first switch OFF the welder, remove the standard MIG torch and MIG
wire then install the Spool Gun in to the euro adapter and connect the control wire plug to the four pin receptacle on
the front panel of the welder. You must Change the Switch from MIG to Spool Gun. This will disable the drive system
of the welder and enable the Spool Gun’s drive system. Reference the owner’s manual of the Spool Gun for operating
procedures and instructions of the Spool Gun. NB: Use Argon gas for aluminium MIG welding.
