Another recommendation for RTech machine , Started using mig welder many years ago with cheapo machines , had a Clark’s one ,results hit and miss then acquired another cheapo machine on eBay and again struggled to get consistent welds , eventually bit the bullet and purchased a R Tech machine 5 years ago and what a difference easy to set up and use . Runs off 13 amp plug and never overloaded the circuit breaker . I used the larger hobbie weld Argon mix gas bottles as once deposit paid no rental and just swop them over when empty .
