Thread: welding question

Tweet

Okay well the hammer and dolly Idea won't work since there won't be any room on the inside to put the dolly ... the wood will be in the way... I saw a good video on setting the welder up.. it said to use what would be a good heat setting then turn the feed all the way down pull the trigger and turn the feed up till you get a good sizzle, then check to see if the penitration is good ... adjust heat if needed then the feed to get the good sizzle.. which I did and the welds came out much better.. I also found if h two pieces are butted up together you need more heat than if there is a little gap between the pieces... is this true? I feel a lot more comfortable about welding now... so If I do 1/2 welds and cool with a wet rag right away and move from side to side the warpage should be minimal? or should I just use thousands of tack welds? I am using a ribbed roof I hope that it will help with keeping the warpage down... any more pointers would be great !!!!

thanks
