Tip: The max point reward for answering a question is 15.
The black lead is connected to the metal you are attempting to weld, it has the silver ground clamp connected to it
The remaining red lead with the electrode holder connected to it holds the electrode
These welders are also capable of using 125 & 230 vac, 1-phase current from your mains there is usually a switchable indicator on the machine allowing you to select the input voltage
This tip is referring to welding machines using fifty foot add on sections of welding leads. Number one: Set the machine with just the stinger whip(six to eight foot long) and a fifty foot ground lead.The ground lead can be shorter. Number two: Get a piece of scrap plate the same thickness as you will be welding. Number three: Set the plate in the position you will be welding in and clamp the on ground to to plate. Number four: Turn on machine and set amperage dial to the size of rod.(if your using 1/8 rod set for 125 which is the decimal equivalent of 1/8) using decimal equivalents will get you in the ball park but depending on the coating , thick or thin you will have to adjust from there. This will work for rods like stainless that have high resistance to current. Number five: Once you have the setting that you like add five amps for every fifty foot of lead your using.This works for copper leads that are half inch thick and that all connections are tight. One more thing,if the rod is eating a crater ahead of the arc your running to hot.
Argon is an inert gas and in welding is used to produce a shield around the weld. It protects the work from impurities. The arch comes directly from amperage shorting to ground through the rod. The heat generated from this short melts the rod into the work. In short, the welder should work without the Argon and needs only Amperage in the rod and a good ground to create an arch. Double check the ground on the work. In this case, your Ring. Please rate this answer for me and feel free to write again. Thank You. Roger
Hi Kevin, Causes of poor penetration: Travel speed too fast, welding current too low, poor joint design / and or preparation, electrode diameter too large, wrong type of electrode, excessively long arc length. Solutions: Decrease travel speed, increase welding current, increase root opening or decrease rootface, use smaller electrode, use electrode with deeper penetration characteristics, reduce arc length.
1.whether it is tranformer type or Rectifiert please find.
2.If Transformer check the oil level.
2.if rectifier Please check the outlet with the meger instrument to find amps generated while you trying to weld
3.Please check earthing cable is fixed directly to the metal where you are going to weld
There are CT;s (current transformers) that the transformer output runs through and the AC outlets which sense the current flow and throttle it up from the control board. Also, Is the throttle linkage free , not jammed up??
