Clarke 90 "Poping" Issue

[the_big_1]

Hi Guys,

I tried welding so 2.6mm box section today. According to the mig manual, all settings to max, wire speed high. I have a Argon / CO2 mix gas set between 4 & 5.

When I tried to weld, it was poping in and off. I turned the speed up but it didnt help.

All the metal was cleaned up etc. Sometimes when it did fuzz, the weld was huge.

Any pointers?

try slowing down the wire speed

gas set between 4 & 5 what ? litres per minute ? do you have a flow gauge, if so set to around 10 lpm

Sounds like your wire was bouncing off the weld to me...too fast.

Not hot enough or poor return contact. Has this set the grunt required?

Hard to diagnose from description

sounds like the set hasn't enough power to weld it,
slow the wire feed down first
big welds sitting on top means not enough amps to penetrate the parent metal
you need to put some pictures up
