Welder review- for anyone interested.
Ended up getting a weldtech 4015mp from an outfit in Christchurch and it turned up three days later. Had been meaning to get a 15A plug sorted out but new toy, so couldn’t wait. This is a multi process machine that does stick welder, plasma cutter and tig. Big part of getting this is the days of chucking the old young model b (pictured below) in the back of the wagon when I needed to weld something out of the workshop are fading. This thing is so light in comparison, and having a plasma cutter has been on my wish list for some years.
First job was cutting out some new tilt linkages for the hedgecutter out of 10mm plate. It seemed to be approaching the limit of its capabilities as a plasma. It might be something to do with the way I’m using it (ie operator error) but I found it impossible to keep a straight cut. In the end I cut the shape slightly wider and ground the cut after to tidy it up. Was fairly slow cutting but this thing has a neat function where you can start it by depressing the trigger once and it will stay on until you lift the hand piece. After this I tried it on some 6mm plate and it cut through like butter, clean and fast. It works good enough for what I want to do, hopefully get better with practice. Next I tried out the welding function on some 10mm off cuts. Oh man, so freaking awesome, so smooth and heaps of grunt. Unfortunately at this point the 70 year old electrics in the workshop decided maybe to much grunt and the lights went out, which revealed around six power outlets in the shed were powered by a short extension cord near the toilet with going out one outlet then in another.
so that’s all good, needed to get an electrician anyways. A week later some cracks started to appear on the head of the hedgecutter so threw the welder in the wagon the next morning. I was a bit dubious about hooking off the power from the farmers shed, running out a long extension lead and welding some fairly thick steel. I set the welder on 95 amps with some 3.2 rods and went at it. Job done-no problems. Pretty stoked, yeah it’s not weld porn but the thing stopped falling in half at least.
In conclusion- this thing is pretty sweet. As a welder it’s probably the best one I’ve used. As a plasma it does what is says, but 10mm is definitely its upper limit. I’ve never done any tig welding before, for me it would have been absolutely ideal if it could be used as a mig. I asked the supplier before I got it if a spool gun type setup could be used on it, which would be adequate for my use, but they said it couldn’t be done. Bit of a shame. I may give the tig part a try one day when I have time just to satisfy my curiosity. At this stage would recommend to anyone looking for this type of machine. Hopefully it stands the test of time.
