20 years ago I bought two transport loads of Miller welders that were used at SEMA ,they were used for demo’s ,and welding classes .Most had a few minutes of use ,some no use at all ,and all of them were literally tossed onto pallets with zero care .They could not be sold to the US ,but I am a Canadian so I bought them cheap ,about $2000.00 total delivered to Buffalo .Anyways ,I sold them mostly one by one locally ,most had zero issues but probably 2 dozen needed some tlc before I would sell them .Anyways ,my son was 10 at the time ,I showed him how to weld with the little migs and he did very well straight out of the gate .Anyways ,some of the older gentleman called me up complaining the mig they bought was no good ,didn’t work etc. which I believed to be false as I literally tested each and every one of them before selling them ,and showed the customer them working at time of purchase .So when I would get the call from the complainers ,I would load my kid up ,another welder just in case ,and go see the guy .I found zero with issues ,other than the operator didn’t know what he was doing or some had small extension cords .I told the gentleman ,I bet my son could weld just fine with the welder and each of them took the bait .My son had no problem welding a nice bead ,and I collected $50.00 for them wasting my time (yes it all went to my son ) .Point is ,it’s not hard to use a mig welder ,easy enough for a 10 year old to pick up very descently in an evening .From there ,stick is an easy step right up to tig which is a little more involved .
