This is an electric arc welding process which fuses together
the parts to be welded by heating them with an arc between a continuous flux filled electrode wire and the
work. Shielding is obtained through decomposition of the flux within the tubular wire. Additional shielding
may or may not be obtained from an externally supplied gas or gas mixture. The process is normally applied
semi automatically; however, the process may be applied automatically or by machine. It is commonly used
to weld large diameter electrodes in the flat and horizontal position and small electrode diameters in all
position. The process is used to a lesser degree for welding stainless steel and for overlay work.
Weld at a Steady Pace do not weave the arc, neither forward, backward, of sideways remove slag with the
Chipping Hammer to expose weld for Horizontal Weld Joins.
Remember: Drag if there's Slag, Refer to manual for Troubleshooting Poor Weld Quality.
ATTENTION - IN CASE OF USING GAS, CHECK THAT THERE ARE NO LEAKS
At initial set up and at regular intervals we recommend to check for gas leakage.
Recommended procedure is as follows:
1. Connect the regulator and gas hose assembly and tighten all connectors and clamps.
2. Slowly open the cylinder valve.
3. Set the flow rate on the regulator to approximately 8-10L/min.
4. Close the cylinder valve and pay attention to the needle indicator of the contents pressure gauge on the
regulator, if the needle drops away towards zero there is a gas leak. Sometime a gas leak can be slow and to
identify it will require leaving the gas pressure in the regulator and line for an extended time period. In this
situation it is recommended to open the cylinder valve, set the flow rate to 8-10L/min, close the cylinder
valve and check after a minimum of 15 minutes.
5. If there is a gas loss then check all connectors and clamps for leakage by brushing or spraying with soapy
water, bubbles will appear at the leakage point.
6. Tighten clamps or fittings to eliminate gas leakage.
We strongly recommend that you check for gas leakage prior to operation of your machine. We recommend
that you close the cylinder valve when the machine is not in use.
7. Do not pull the welding gun back when the arc is established. This will create excessive wire extension
(stick-out) and make a very poor weld.
Preselected variables depend upon the type of material being welded, the thickness of the material, the
welding position, the deposition rate and the mechanical properties.
These variables are:
1. Type of electrode wire
2. Size of electrode wire
3. Type of gas (not applicable to self-shielding wires FCAW)
4. Gas flow rate (not applicable to self-shielding wires FCAW)
Adjustable Variables
1. Stick-out (distance between the end of the contact tube (tip) and the end of the electrode wire). Maintain
at about 10mm stick-out.
2. Wire Feed Speed. Increase in wire feed speed increases weld current, Decrease in wire feed
speed decreases weld current.
