Description
ClassificationAWS A5.20 E71T-14/GS
Shielding gasNone (self-shielded)
PolarityDC- (electrode negative)
PositionsAll positions, single pass
ESAB Gas Free is an all-position self-shielded flux cored welding wire for single-pass work. Because it makes its own shielding, you don’t need a gas bottle, which makes it ideal for site work, outdoor repairs and small gasless MIG welders.
It gives a smooth arc, full slag cover that lifts off easily, and low spatter. It runs on DC electrode negative (DCEN), which keeps heat input down and reduces the risk of burning through thin sheet.
Where to use it
- Lap and fillet welds on thin gauge galvanised and mild steel, in all positions
- Thin sheet from 0.8 mm up to 5 mm, including galvanised, zinc-aluminium coated and aluminised carbon steels
- The 0.8 mm wire can be used on material as thin as 18 gauge (1.2 mm)
- Structural fabrication where there are no seismic requirements
- Single-pass welds only
