Further to my other thread where I wanted a comparison of Arc vs Mig in terms of speed, I thought I'd ask a related question in a new thread.
I make car ramps - big ones - either for displaying cars (or transits!), or to get them a couple of feet off the ground to work underneath.
The part of the ramp where the vehicle runs up is made of 25mm x 25mm x 3mm angle, welded crossways (at the ends) to 50mmx50mmx6mm angle.
There are 72 of these infill pieces, 4 welds (each 45mm long) to each piece - two either end, and it usually takes me about 3-4 hours to fit and weld them, probably around 60% duty cycle, possibly more.
So, I'm thinking of buying a mig welder - probably a Clarke 135A.
But... what duty cycle to weld 3mm steel?
I run the buzz box (190TE) at 90A (ish) - but I'm not sure how wire speed/voltage setting on a MIG correlates.
The 135TE says 57A at 60% duty cyle, or 115A @ 15%, so I'm thinking 30-35% @ 90A?
Would that be about right? 35% duty cycle to weld 3mm steel? or is the amperage completely different on a MIG?
