Some time ago i said that Amazon uk was selling a Chinese/German 250 amp mig welder,that seemed identical to the R-Tech model,at less than half the R-Tech price,well i bought it and it an amazing machine,well i have lost track of that ad. Amazon no longer sells it. It got such good reviews i thought it would be an Amazon bulwark,i forget the German co.name. There is a 250 amp mig on Amazon it looks faintly similar,but does not light up the bulb,and is not German.It was 2 or 3 years ago,so i guess time moves on.Cheers.Ronnie.
