The trolley is galvanized steel so make sure that you grind off the zinc coating before you weld and wear a mask or work out in the open and stay away from the fumes.
I don't really like the way you've fitted the welder into the trolley. It would be better to remove the grill and make a shelf...
Years ago I fabricated a 316 stainless exhaust system for my old Triumph Trident. I only had pure Argon so that's what I used. I know you're supposed to use an Argon Co2 mix but just for that job it wouldn't be worth buying the bottle. In the end the welding went very well and the results were...
I'm sorry if I appear to be confrontational ,not my intention at all, but I find it very hard to go against evidence. As I said there are better or ideal ways to weld 12mm plate but according to the results that I've arrived at this method has proven to be adequate. Not perfect mind.
My point exactly. I will happilly spray transfer my 12mm plate given the 200 plus amps and proper gas.I go with facts. I make a test piece, take it to a hydraulic press and bend it as far as I can. It doesn't break so it's sound. Preparation was properly done. Many professionals use the weaving...
I made a test piece to prove my point ,that is ,you can successfully weld 12mm plate with a 180 amp Mig welder. I used 0.8mm wire on straight CO2 which actually increases penetration. The test piece is not perfect because I couldn't have it bend any further on the press for lack of the correct...
I agree of course but experience and testing have taught me a thing or two.When welding 5mm plate I use about 140amps (hard to tell on the R Tech equipment) and by bevelling(rooting) I get very good integrity and penetration. When welding 12mm plate I start at the root,achieve a good deep puddle...
I don't know how you guys measure your amps but I have been making anchors out of 12mm plate that never break with my R Tech 180 Mig welder. It's how you prepare the welding and how you do the welding that counts given decent levels of power of course. Every joint is bevelled and gapped. I...
Presently it only controls the wire feed motor.When I first installed it this morning if I left the machine on for 20 mns or so the contactor would work albeit with a lot of chattering and arcing and the gas solenoid valve would also work.I managed to weld a bit after the contactor stabilized...
Thought I'd replied to your post but can't find it. I could leave the PCB in place because it's still powering and controlling the wire feed motor and install two separate relays for the contactor and gas valve. Would this be feasible?
By features what exactly do you mean? It's a simple thing.It has a spot timer,never used, and a rotary switch with 6 positions. Wire speed is controlled by a knob on the PCB which still works actually so I could probably leave that in.
