Hi I've spent the last few weeks making a fair bit of mess but things are starting to improve. lots of head scratching about settings on my Clarke 160TM
I can now lay a reasonable bead on 3mm flat sheet, although I am seeing rather a lot of fine brown residue which never seem to appear in any of the UT vids I have watched.
I am trying my hand at some joints T'ing 3 mm hollow square section 50mm x 50mm
On the flat surfaces I am getting reasonable results but I am having a rough time when it comes to welding up the 90 degree faces. Rather than forming a nice concave bead I am getting a huge build up of metal that can be best described as a sausage in the root of the joint.
I am running at max power as I am assuming 3mm is going towards the upper end of the 160TM range and wire feed at about 50% (sorry not around to converting the wire speed setting to meters per min, it would be helpful if Clarke and others put real unit of dials sigh) using Hobby Weld 5 and 0.8mm wire.
Where could I be going wrong?
Sorry no pics I don't have anything to take any with at the moment.
On a different topic, I am learning at this scale but want to be welding much thicker stock 10 - 20mm + as most of our need is agricultural fabrication and repair. To work at that sort of scale am going to have to make a really big jump in machine size, if so how big (I know yet another how long is a piece of string question).
Any suggestions would be appreciated.
