When dad sees how nice the temps hold and how little tending there is to the fire, you'll see a smile develop....you'll know he approves of your design...
As far as the welds go, look at the back of the piece of metal and see if the heat penetrated.... The weld in post #30 looks like it could use more heat..... the bead didn't flow too well into the metal.... kind of piled up in the middle...
It looks like you are using flux core.... the tip in the gun, on my MIG, protrudes about 1/8-3/16" past the end of the nozzle... I run CV (Constant Voltage) DC-, generally about 20 volts using 0.030 wire..... wire speed, when you hear a pleasant buzzing sound, you are very close...
Do you have a knob to turn up the voltage/amperage ?? 1/2-1 volt or 5 amps should do fine.... depends on if you are running CC or CV..
Not knowing what machine and wire and gas and voltage/current is making this difficult to trouble shoot.... Dave
If you changed wire size, the feed roller may or may not be gripping the wire for a smooth feed.... there should be an adjustment by the wire roll for the feed roller to grip the wire correctly.... also, the brass tip on the gun is sized for wire size.... that brass tip is what conducts the electricity to the wire or in DC- makes contact with the ground to complete the circuit.....
Looking at the welders, is this yours ??
