wire size?

[-matt]

i have been learning to weld using a clarke 100E mig welder. To do the engine mounts on my kit car, which will use 2mm steel.

To start with i was using the gassless 0.6mm wire that came with it and was doing ok, i was doing a really strong weld (it was a case of hitting it with a hammer for a couple of mins to break it), but was not very neat.

but that ran out and i bought some 0.9MM gassless wire, and am having problems with it.

i take it i need to slow the wire speed down with this and move slower, but i seem to be either making a weak weld or burning a hole through.

so is 0.9mm wire too thick for 2mm steel, or do i just need to practice?

cheers

Noone makes 0.6mm gasless wire, didn't you mean 0.8mm?

You would want to move faster if the wire is thicker.

I'd suggest getting some gas and normal wire.

I have a 100E as well

there is a chart in the handbook that gives reference settings for use with Gas and normal wire;

for up to 2.0mm thick on 0.6mm wire you need it set to A-2-MIN, wire speed 6/7,

for 2-3mm it suggests A-3-MAX and wire at 7/8.

for 0.8mm wire and up to 2mm the settings suggested are A-3-MAX wire 6/7, and for 2-3mm A-3-MAX wire on 8.

have you mixed up the wire sizes gas less might be .9mm and the solid core .6mm
