5.Inch the electrode through the gun and cable and then cut the electrode within approximately 3/8 inch (9.5 mm) of the end of the contact tip [3/4 inch (19 mm) for Outershield® electrodes].
6.If welding gas is to be used, turn on the gas sup- ply and set the required flow rate [typically
7.When using Innershield® electrode, the gas noz- zle may be removed from the insulation on the end of the gun and replaced with the gasless noz- zle. This will give improved visibility and eliminate the possibility of the gas nozzle overheating.
8.Connect work clamp to metal to be welded. Work clamp must make good electrical contact to the work. The work must also be grounded as stated in “Arc Welding Safety Precautions”.
WARNING
When using an open arc process, it is necessary to use correct eye, head, and body protection.
9.Position electrode over joint. End of electrode may be lightly touching the work.
10.Lower welding helmet, close gun trigger, and begin welding. Hold the gun so the contact tip to work distance is about 3/8 inch (9.5 mm), [3/4 inch (19 mm) for Outershield electrodes].
11.To stop welding, release the gun trigger and then pull the gun away from the work after the arc goes out.
