Is your R Tech an inverter type?.This morning I installed a new reel of wire on my 250-1 mig, and according to my records this is the 67th 15kg roll or 1000kg/1 ton of 0.8mm A18 wire that I have installed into my welder since I purchased it a little over 2 years ago or about one reel consumed every 8-10 working days.
My 250-1 has also pushed 75kg of 1.0mm A.18, about 10kg O.6mm A18 and a single 15kg reel of 316 stainless steel during this period making about 1100kgs of wire in total
