The torch switch must be pressed thoroughly to perform its three functions: gas
flow, wire feed and welding current.) Start welding and decrease the wire speed gradually.
Continue to decrease the wire speed and listen to the sound. The sound will change from a
crackling noise to a regular and strong buzzing (similar to the sound of frying bacon). This
buzzing sound indicates the correct wire speed for the workpiece being welded. When the
current regulation is changed, reset the wire speed. ALWAYS start from a higher wire speed.
This operation prevents damage to the contact tip during welding. During welding, keep the
torch at a 45º angle from the workpiece. Keep the nozzle 1/4” to 1/2” from the workpiece.
