The Gauge Technique has been applied to QED2+1 in the quenched case with infrared subtraction. The behaviour of the fermion propagator near the threshold is then found to be S(p)→ \frac(γ⋅ p+m)(p2-m2)(\fracp2-m2% 2m2)ζexp (-(ης)/(2)), where ς=e2/(4πm) and this is gauge invariant except the exponential factor. We also find a spectral function in the Landau and Yennie like gauge. The propagators S(p) are expressed in terms of Φ(z,1,ς) explicitly .The vacuum expectation value < ψψ> is gauge dependent . Thus dynamical mass generation does not occur.
