Abstract
The Gauge Technique has been applied to QED in the quenched case with infrared subtraction. The behaviour of the fermion propagator near the threshold is then found to be S(p)\to \frac{(\gamma \cdot p+m)}{(p^{2}-m^{2})}(\frac{p^{2}-m^{2}}{% 2m^{2}})^{\zeta}\exp (-\frac{\eta \varsigma}{2}), where and this is gauge invariant except the exponential factor. We also find a spectral function in the Landau and Yennie like gauge. The propagators are expressed in terms of explicitly .The vacuum expectation value is gauge dependent . Thus dynamical mass generation does not occur.
