I had to buy a few bits to get it to a working state but now I can use it I realise that I dont know what all the settings do.

Sealey Mighty Mig 100 Manual For It

I have contacted Sealey and have downloaded the manual for it which contains nothing about the controls on the front, I also have the parts list too in the hope that it tells you the name of the controls.

Does anyone know what they all do Or have tried and tested settings for different welds.

Some are obvious like the wire speed dial but the others dont seem to very intuative.

Current is determined by the thickness of the wire, the gas used and the distance to the work.

A 0.8mm wire with 14 gap may be 35A all with the same settings.

Like on the MightyMIG 130XT above, mine has two rocker switches labeled MinMax and 12.

Heat setting Min1 Max1 Max2 Output current 30A 75A 105A Output voltage 15.5V 17.8V 19.2V Duty cycle 100 25 15 (I hope that is clear - there are 4 columns there, the right 3 with the data.) Elsewhere ij the manual there is Recommended voltage and wire settings for thickness of metal being welded.

Number on right of slash is wire feed setting.

For 0.8mm wire: 1.2mm material, set 16 1.6mm.

Sealey Mighty Mig 100 How To Remedy Poor

Also in the manual, in discussion of how to remedy poor welding, the manual speaks of higher or lower voltagecurrentheat seemingly interchangeably.

Obviously, all things being equal, more voltage will force more current and produce more heat, so thats fair enough.

Do these manual writers assume some basic welding knowledge There is a lot of details in some places, and a bit scant in others.

I am asking this in detail because I dont think the same question was adequately answered by I just know about what to set it from experience above.

In the video the guy explains about the heat and the switches.

For my MIG welder rated at 150 Amp peak welding power, Min1 is for thin panel up to 2mm thick Min2 is for material 2 to 4 mm Max1 is for 4 to 6 mm Max2 is max power output.

I suppose these switches are selecting the different windings on the transformer secondary.
