Welding Preparation
• Attach the ground clamp to the bare metal to be welded, making sure of good contact;
• Make sure that the wire-roller groove in the roller corresponds to the diameter of the wire
being used.
• Plug the machine into a suitable outlet.
• Completely open the gas cylinder valve. Adjust the gas pressure regulator to the correct
flow rate.
Factors to Consider for Best Welding Results
Some experience is required to adjust and use a MIG welder. In MIG welding two parameters are
fundamental: the welding voltage and the wire speed. The resulting welding current is a result of these
two settings.
• Set the voltage and wire feed controls to positions suitable for the thickness of the material
to be welded. Welding current varies in relationship to wire feed speed. For low welding
current output, the wire feed speed potentiometer should be set at the low end of the wire
feed speed scale. Turning the wire feed speed control potentiometer clockwise will result
in increased wire feed speed and welding current. Welding voltage is adjusted to match
the wire feed speed (welding current). Progressively select higher voltage positions while
increasing wire speed.
