Signed up to some evening classes at the local college, last week was just paperwork, this week got to strike an arc
So never welded before, so just getting to grips with the machine really. Here are a couple of photos of my work
So ignore the lap joint, I was just using the flat section of steel below it. Starting on top right with a smooth weld, then another 2 smooth welds along beside it, then a coupe of runs of small zig zags without a pause at the points. Then a couple runs or loops. Finally 2 rows of zig zags with a longer pause and bit wider with final weld, probably too wide. That was done on a bit of 6mm steel
So with the final weld on that sheet a bit wide and flat, chose to put the welder up 1 click of voltage, and do smaller loops, as they seemed to make the best looking beads so far
So again, started on top right with a leftward push, first run was smooth and quite fast just to get something down to line the 2nd weld against, top edge of this 8mm steel was just cut with a torch. 2nd run was just small loops again, weld appeared a nice width. 3rd weld was a bit of a different noise, and felt like wire was hitting back of pool, so turned the wire speed down half a digit, 4th weld sounded even more different and sounded like machine was struggling to keep up, and about an inch from the left the arc stopped and realised the wire had welded to the tip, cue about 30mins and running fresh wire through the gun 3 times. Didnt initially realise why the welding wasnt as smooth, but when i put the feed rate higher everything was going well again. so bottom 2 runs on the flat are with the same setting. Thet both looked nice and straight so thought i'd try a T weld the 8mm down onto a bit of 5mm, managed the first 2 inches but then time was up, but i'm quite impressed with the weld considering its my first lesson with the welder.
