We examine the potential of the e-p → e-γ^*p → e-W-q'X (γ^* is Weizsacker-Willams photon) reaction to probe the non-standard W+W-γ couplings at the Large Hadron electron Collider (LHeC) and the Future Circular Collider-hadron electron (FCC-he). We find 95% confidence level bounds on the anomalous coupling Δκγ and λγ parameters in the view of effective Lagrangian approach with various values of the integrated luminosity. We assume center-of-mass energies of the electron-proton system √(s)= 1.30, 1.98, 7.07, 10\hspace0.8mm\rm TeV and luminosities \cal L = 10-1000 \hspace0.8mm\rm fb-1. The best limits obtained from the process e-p → e-γ^*p → e-W-q'X on the anomalous Δκγ and λγ couplings are Δκγ= |0.00069| and λγ= [-0.0099, 0.0054]. These bounds show that the process under consideration is a good prospect for the searching of the non-standard Δκγ and λγ couplings at the LHeC and the FCC-he. In addition, our results provide complementary information on other results for Δκγ and λγ couplings.
