-
06 January 2022As stated previously, I have only been getting used to the equipment and I have not used it for long periods. I will be using the equipment mainly to repair vehicle bodies, however, my wife has suggested that I could make some arches for plants to grow around in the garden. So a bit of variety. From what I have seen so far, I would suggest that it is a machine for any hobby welder or light commercial use. I was impressed with the quality of the earth clamp and the consistency of the wire supply. Time will tell about the longevity. However, I was also impressed regarding the 3 year warranty.

23 July 2018Welding a classic car needs top quality consumables, and the SIF 0.6mm wire is just that; I already use SIF rods for arc welding, and the product is a reflection of R-tech's standards, chosen to match their machines.
