Well I've been gone & dunnit .
I'm now the owner of an GYS Pearl 200 - 2 ( from Weld equip ) . Have Co2 argon mix & an argon cylinder
I think I've re learnt how to arc weld with it found it strange at first especially in computer mode . Made a work bench of sorts , the welds got better to the end of things as I tweaked things related to fine control .. something my old buzz box turbo never had .
This afternoon I've been exploring Mig side of steel welding 1.5 mm thin electro galvanized tubes ....square & round , using the synergy settings.
It's a darn good job it came with a hand book of sorts for I was totally clueless .
It seems strange having to set the welder and do several test pieces to see if it needs individual parameters adjusting to get a better weld .It's nothing like the ancient Clarke EN90 thing I borrowed and almost instantly I handed back to its owner.
Eventually I got it to stop spitting & jumping about .. .( having the C02 turned on at the cylinder helps ) . I was able to lay several caterpillars of weld on top of the scrap test piece , getting a bit more confident on each run till eventually i turned the thickness figure up from 1.5 mm ( the measured wall is 1.56 mm ) to 1.8 mm and finally got the better laid in fused weld i was after . This also involved having to set the flow Co2 Argon mix gauge at 8 litres per min ,up from the six I'd started with .
Now getting big headed and a bit over confident I decided to try and do some of the jobs that I'd purchased the welder for.
They involve welding a slightly crushed end of round tube ( don't have a notcher for this task so did the obvious to get it a better fit ) with a wall of 1.5 mm at right angles on to a round tube at 90 degree to the vertical .
I then found that I need help for you guys for my welds were at first terrible like hemorrhoids on a tube .
I now realise that trying to MIG join two round surfaces of thin wall gives forth lots of problems , mainy I suspect the gas flow & mini gas thermal currents etc.
I've tried welding at just over 30 degrees from the vertical tube on to the horizontal one , every now & then I blew a small hole in the horizontal tube . ( they filled in well )
Would increasing the gas flow to say 10 litres per min help in keeping then weld cooler or is it over kill ?
Is the angle I'm welding at about right ?
There is a setting referred to as Spot I'm not 100 % sure what it is for . if I turn the control knob for it, It appears to affect the length of the time I keep an arc going . Am I correct in assuming that doing MIG with this type of welder you ought to weld in short bursts to keep heat down ( It can be set from 0 to 10 seconds )
