Postalloy® 344
Postalloy® 344 is a high strength mild steel electrode offering very smooth operation coupled with superior out-of-position weldability and penetration. It is ideal for welding thin, medium, heavy and dissimilar gauge steel.
- Easy "all position" weldability
- Ideal for poor-fit work
- Low sparking
Never before has an electrode been made that offers both smooth operating features with such as outstanding ability to weld out of position. Welding positions such as vertical up and down, flat or horizontal fillets, and overhead can be easily accomplished. With Postalloy® 344 you won't have to spend time positioning the work to make a perfect joint. With its quick-freezing slag and steady arc, it will easily bridge or fill a gap. Best of all, Postalloy® 344 won't burn you up. Good penetration does not mean that the sparks have to fly and this is especially true with Postalloy® 344.

| Amps | Diameter |
|---|---|
| 40-80 | 3/32" (2.4mm) |
| 70-125 | 1/8" (3.2mm) |
| 120-175 | 5/32" (4mm) |
Welding Procedure:
Although it is best to clean the surface prior to welding, Postalloy® 344 will weld through rust, paint and other contaminants when it isnecessary. Amperages should be increased slightly. When welding thin materials, use the lowest possible amperage and maintain close arc. Postalloy® 344 may be used with a drag technique or with a gap.
