Hello,
I'm obviously new here.
I began welding alsmost 30 years ago and started with Mig Miller 130, Oxy/acetylene cutting etc. then moved up to Stick welding.
relocated to Germany from US many years ago and since then have only stick welded. I've recently aquired a used and in very good condition kemppi kempoweld 150. Starting with the Mig again felt strange after stick welding for so long. I'm starting with 2mm square tubing using 0,8mm solid, wire and cargon 18 gas set-up for a commision. And although my beeds, after tinkering with the settings and gas flow for a whole day are smooth and uniform, they seem a little too high and bulky compared to my earlier beeds with the Miller 130 on similar and thicker materials.
It then occured to me that the Gas nozzle is possibly too long for the the tip length because the tip sits a good 8 mm recessed into the nozzle. That means I have over 10mm of wire already sticking out from tip to workpiece when welding inkluding the fact that the gas release holes of the tip holder do not reach completely into the inner insolation ring inside the nozzle and begins behind the edges of the inner ring and the gas is for all intent and purposes impeded from fully going forward toward the arc to provide the schield for the right heat etc. This set-up appears to be originbal for this Kemppi welder beacause all replacement parts, as far as I've been able to find for it, have the same measurements ei. nozzle length, 61mm, tip length M6 x 28mm.
So finally to my question: Does anyone have experience with this welder? And or does this nozzle-tip-tipholder distance seem unusual or problematic?
Many thanks for any helpful repliues!
