Choosing the correct replacement/filler material is critical to all field repair applications. All material should be replaced with one that meets or exceeds the strength of the parent material.

Choosing the correct replacement/filler material is critical to all field repair applications. All material should be replaced with one that meets or exceeds the strength of the parent material. 

Selecting the right machine for Stick welding is based largely on the diameter of electrodes used. A 1/8-in. electrode welds up to 145 amps, while a 5/32-in. electrode offers optimal performance at about 180 amps. Therefore, a welding generator with a 100 percent duty cycle at 250 amps (Miller's Bobcat™ 250) offers enough welding power to meet most Stick welding needs. 

Stick welding in the flat, horizontal and overhead position uses a “drag” or “backhand” welding technique. Hold the electrode perpendicular to the joint and tilt the top of the electrode in the direction of travel approximately 5 to 15 degrees. For welding vertical up, use a “push” or “forehand” technique and tilt the top of the electrode 15 degrees away from the direction of travel.
