Hi We have just bought a migwelder at work and having only used mma in the past are a little unsure which gas would be best suited for our purposes? We would be welding 25mm mild steel plate any help or advice would be gratefully received thanks
for 25mm arcsheild heavy or simalar if not heavyer / hotter mix. with the biggest wire that your welder will spray.
1.0mm can do 25mm but it's slow and you are going to be filling the joint up for a long time. and it''ll want good prep to get an accseptable weld. 1.2mm really is smallest wire you want to be useing imo.
if you havent got one yet i'd suggest purchaseing a watercooler and watercooled torch something like an MB501
